If you want extra safety add ground wire to the Aluminium heat-bed or to adjusting screw and connect it to the ground directly or on the power-supply ground terminal or on ground pin on the main AC plug switch.
Also for even more extra safety install Anycubic Ultrabase(that's what i did after this video) and don't use paper clamps. I'am afraid that using paper clamps over and over for long period of time may damage the heatpad and expose main wires.
Thank you!
Nexi Tech can you show us how to put marlin on to try and get higher temperatures? Thanks
You should not have used common transparent tape to isolate the mains cables! Each cable should be individually isolated with heatshrink tubing (very cheap from the hardware store).
guillep2k What transparent tape? Where did I used it? Yes I know what is the heat-shrink I have the full box of it in different colors.
4:44 over the thermistor wire. You shouldn't have used any kind of tape because a) tape dries with time and becomes a liability and 2) the one you used looks like very easy to puncture. In other comments you say you don't worry about the connector because the amperage will be less (which is correct) but the problem is voltage: some ambient humidity and you could have your mains voltage creep to the case; that's why someone suggested you put a ground connection to the case and the bed. And those connectors are typically rated for low voltage with a dielectric strength of 250 Vrms (not enough for your safety). I sincerely recommend you to add heat-shrink inside the connectors (both male and female).
guillep2k Can't you see that I just use that tape to stick thermistor wires to another cable so I can drag them thru the cable housing?! You didn't even look video carefully. Over connector wires there is electrical black tape and there is plastic thick transparent ring over it inside the connector. Like I said in the comments use this video as idea or reference and do this updgrade it in your way.
Thank you for such a well done step by step video. I read what Peter has said, but the reality is that the only possible valid criticism is that a ground would be a good idea. Everything else is nicely thought out and implemented and even the ground is debatable. I love that your “rebuttal” had such good answers. This is why it is important for viewers to ask questions rather than jumping to conclusions. You are not an idiot, and IMO viewers should show more respect to people such as yourself who do us such a good service.
At the same time, we need Peters to raise questions that the less knowledgeable need to be aware of. Awesome that no flaming went on and communications persisted to a conclusion. I was just admiring both of you. It all added to the depth of this video in the end.
Your instruction is awesome! It’s amazing how fast the bed heats up now. Only thing I did different was ground the printer chassis and took out the aviation connector completely.
I'm digging the new intro! Keep the great videos coming, it's always interesting to see what you're up-to.
Thanks for posting this, I bought a 1000w heater for my CR10S S4...with the stock heater it was taking 25 minutes to get to 60 degrees...I followed your example and everything went perfectly. Now my heatbed hits 100 degrees easily in just a couple of minutes. Very pleased with it and very pleased you posted this.
Heya. Still happy? It felt to me like less hassle to buy secondary 24V power supply. I also did not like how long it took to get at 60 degrees. Now its fast, and at 24.2V, it goes to 120 degrees in reasonable 12 minutes, to not overstress the stock bed. 60 degrees is very fast, 85 very nice, 100, fine. Almost no work, 50 dollars for the supply.
Update? Is it still working?
I did this mod to my CR-10 today. I had bought in advance a breaker for the heating mat. In the process of the modification I noticed that the socket for the power cord has an AC fuse built into it and since the tap for the AC power is downstream of the fuse, a separate breaker is not needed. That said, the mod works beautifully. Thank you "Nexi Tech" for posting this video!
Although you have done that, I suggest putting a ground wire. Just a suggestion, it's your choice though. I put the ground wire though
Amazing. Thank you! I was wiring my SSR wrong. This helped a lot.
I stupidly tried setting mine up by guessing. Was sure I fried my board (you know the smell), but once I got it hooked up like yours, I'm back baby!!! Thanks for taking the time to make this. And props for thoroughness and safety.
just got my 110V heated pad - I noticed that the wires were a bit shorter for power... oh well - I will splice them up! Thanks for the great video!!
Any long term problems to report?
Thanks for the guide! Bed heats up for PLA in less than a minute now!
This is the best mod to my CR10 I’ve done to date. The speed at which the heated bed reaches temp is outstanding!
Thomas Love I agree :) P.S. I installed stepper motor dampers. OMG what the difference in the sound and vibrations! It's like night and day! So much silent.
Is it still working? Any problems?
Easy upgrade 👍. Great tip, solder and pull through the new wires. Genius 👍
I got it figured out. Using a multimeter I was able to locate the correct pins to connect to the SSR. It's time for reassembly. Thanks so much for the best guide on this heater upgrade.
Good work my friend! I'm glad that it worked for you. Thanks for stopping by,
Thanks a lot... Followed the instructions and worked perfectly. Bed goes to 100C in less than 2 min
I actually just found this bed a couple days ago since my heated bed died. Wasn't sure if I wanted to get it because it wasn't wired in directly but with this! Super awesome
Is it still working?
Great video, just finished installing my new heater and it's sooo fast.
Followed your instructions, using 110VAC pad, 115 C in minutes now, thanks for the great video.
did you try get 120c or more with the upgrade?
What 110 pad did you use?
Is it still working?
Magic! That's how you are going to make it heat that quick LOL, nice work.
Thanks!! Exactly what I needed. Got this pad in 120V edition. Installing it now. Thanks again!
Excellent tutorial! Although I will not be doing this I sure do like your informative videos!
Finally got around to doing this, and wish I had done it sooner. Was a little nervous as I am not an electrical expert, however following this video closely resulted in highly successful results. Thank you sir!
Is it still working? Any hazards?
In a sea of mass confusion, your instructional video was very refreshing. Whoever manufacturers that SSR and heated bed should be paying you for boosting sales.
Thanks man, I just installed my new heating pad and I have no idea how to get it to work lol. I just purchased an ssr and soldering gun and will do the wiring next weekend. Hopefully I can get my printer up and running then 👍
Phew I'm glad others have mentioned adding some earthing to increase electrical safety!
Thank you so much, followed your instruction step by step and worked like a charm!
I'm glad it worked for you as well :)
Nice work. As a professional technician it's nice to see a guy work with care.
Great thanks for this! Can you also please do a video upgrading the hotend for high temp filaments such as ABS ?
Hi Nexi, good instructional video as usual. Be careful with this one though. There is now 220v A.C. on a machine chassis that was purposed for 24v. There does not seem to be additional grounding on the printer for the 220v circuit. Just a heads up on regulation in case someone decides to flag.
Thanks for detailed manual.
Very good step-by-step guide. Thanks!
Thanks for this great job, much appreciated. It's a shame there are so many negative commenters, if they know better then why not be positive and demonstrate a better way of doing it if they are able to.
I have now implemented this upgrade and it's working well, many thanks.
Just to help others with CR-10S, there is a capacitor upgrade for the heatbed temp contol on the mainboard, covered by Tim Hoogland at TH3D, to stabilise temp fluctuations caused by voltage ripple, well worth looking at.
Still working? Any problems?
Firmware upgrade - how to do?
Yesterday i bought a second-hand CR-10 - S4 printer. It's manufacture date must be late 2017 according to the labels inside it. I have a CR-10S - S3 bought in Oct. 2018 (new) and it's firmware is very different from this one.
Below a few issues you should consider when owning and using a 3D printer:
I was actually surprised how much maintenance is needed when I bought my first printer. However it's essential to get a good print quality.
The printer I bought had not had proper maintenance during it's use. It did, however, have a lot of expensive upgrades, but the basics had been neglected.
I have found several screws that were not tightened, the Z-axis motor would climb up the rail when activated instead of moving the Z-axis. Both retainers for the Z-axis screws were loose and didn't help much with precision movement. Both belts were out of alignment and severely worn.
So far I have spent approximately €50 for spare parts. These are parts that I had in stock for my old printer, but I think I'll have to spend €50 more. Luckily I got it very cheap as nobody else had responded to the add.
Really useful guide, thank you!
Worked perfectly. This is really the way it should be from the factory.
I find it warps up my magnetic bed until the whole surface equalizes.. Something that didn't happen before because it was so incredibly slow.
Not a deal breaker, but something to keep in mind for some who aren't using glass.
thanks, i was wondering about that, my thermistor went out a while back so im gonna do this. how long did it take for the magnetic cover to equalize? this might be a concern if the print is interrupted but maybe a broken filament or other unplanned event.. especially when using exotic plastics.
@@SteveHabermacher Not too long. A few minutes, but it's something to take into consideration.. I find if I preheat the bed before I run the print, it's usually figured itself out and sitting flat again.
I've taken to using a pop up vinyl grow tent as an enclosure to keep things nice and toasty around the print anyway, so this preheating makes sense to warm the enclosure too.
Fyi... followed this great video to add a 1200w heater to my cr10-s5. Worked great but due to the increased power, I started blowing fuses. Bumped the AC fuse up to 15A and for safety I replaced all the AC wires in the control box with 14 gauge. I was pulling a steady 13A when the heater cycled on. Thanks again for this! Hope my comment helps anyone installing a larger heater.
Awesome! Thanks for info and feedback. Wish you a great day! Good luck with your S5 monster 3D printer :)
I have a cr10-s5 and have been wanting to do this upgrade to a 1200w heater as well other than the fuse and replacing the wiring wich i will be doing do you have any other suggestions and how is yours working out
Very nice video looked everywhere on youtube and it wasn't explained yet. The only thing I would do different is adding a fuse in series.
marko rodriguez Thank you. I fact I was thinking to add fuse the heater on AC line but there is a fuse on the back of control box already where AC plug are and it's 10A rated. 10A x 220V= 2200w. I think it's enough for whole 3D printer with this upgrade. It's maybe good think to add ground somewhere but there is glass over aluminium heatbed and whole heatbed is rolling on plastic so it's isolated from rest of printer. Even if something short out fuse in control box will blow and cut main AC.
I followed along with this video and it worked perfectly. Thanks!!
You're welcome!
thx for this!
did the same upgrade and now my bed need exactly 23 mins to reach 100°C .
best upgrade ever :)
Was it really the same upgrade? Your time doesn't match his at all.
@@lapidations maybe he's plugged in a 110v
needs proper earthing + fuse to be added for protection though its a great idea thx for sharing ,
Thanks bro!
I've did forgot the name of the "Mosfet" that we can use on 120V to plug my new silicone 120v 750w hotbed mat.
Alex from Québec, Canada
Alexandre Valiquette It's called solid state relay. You have link in video description. Add the ground wire too man! Never be to safe :)
I completed this upgrade today. I followed this video step by step along with a couple others and combined them. I had a few minor differences. my mother board heat bed connectors 1 black ground and one red positive were connected to connector 5 and 6 labeled as hot bed not 3 and 4 on my creality CR10s 2.1 motherboard and i kept it the same with the new heat bed connections. I ran a ground from the bed base to frame and frame to control box. I also put a 133c thermo fuse between the bed and insulation inline on the power wire that runs to number #1 pin on the plug. I also updated the thermistor type, max bed temp, and with more power comes along with more responsibility so I updated the thermo runout settings in marlin 2.0.9.3 firmware, compiled and uploaded perfectly. Finally set the bed temp to 100c and hit 100c in 2 minutes 10 seconds and 110c at 2 minutes 34 seconds with no heat error whats so ever. I am happy with this upgrade that cost roughly 70 dollars ordering all parts on amazon. The only problem I still have is that Octoprint still reports power supply under voltage to my raspberry pi and I really thought that would be resolved with this upgrade with the powersupply not being used to heat the bed anymore. I seriously give up on the undervoltage issue as it does not affect printing at all and I have tried everything except buy a new power supply and still get undervoltage warning from octoprint even after isolating the number 1, 5v pin in the usb plug with electrical tape as recommended on the gethub website. I never had this problem until upgrading my octoprint 1.7.2 and PI OS to 0.18.0. it seems they are always screwing up something with octoprint daily and I wish they would leave it alone and stop creating more problems with each update!!!! If anyone has had this same problem and has been able to resole it, please let me know how you resolved it, otherwise Cheers to a great heat bed upgrade video that will work perfectly if followed correctly and thank you so much for your time and effort!
Again other excelent vídeo. Thanks @Nexi Tech.
Damn good tutorial. Straight to the point. Thank you.
Thanks, excellent info. I like this machine.
Dears, I just bought a CR10S - Thanks to Nexi's videos - Really useful and well done videos - OK I really wanted to make those modifications and I'm not a rookie regarding electronics stuff but reading all those comments below I don't know whose is right and/or wrong.
The point is if the heatbed is enought insulated from the rest of chassis and build plate there are reasons to have fault ... but I'm maybe wrong ...
There is maybe one thing, is it possible Nexi please to add a clear diagram for wiring in the power supply ? it would be really helpful for me !
And @ the end maybe we just have to make some holes in chassis and build plate and put them @ the ground no ???
Many thanks for your feedbacks guys, because I really want to make this upgrade safely.
Thanks for sharing this content. It's awesome.
EDIT: SOLVED just add a ground wire!
Recently I bought a E3D heated bed (E-BED-HT-300-300-240V-KIT). After installing it following your excellent video, the test worked fine. 135 degrees (according to the controlbox) within no time and I could see the relay do it's work. Nice.
But the I felt a little tingle when I touched the heated bed (when it wasn't warm anymore). I examined the edge of the heated bed...it was smooth. Then I found out that the tingling was only the case when I touched the heated bed and the control unit of the printer...oops. I got out my volt meter and started to measure on the control unit trying to find the point where I f*cked up. Everyting was connected according to the video and shielded properly. And there was no current on places where it shouldn't.
Then I pointed my research on the heated bed. Holding my volt meter between the heated bed and the ground pin of a wall socket it happily showed 230 volts. Is there a flaw in the video? I looked at the wiring. The neutral of the power supply went to the connector of the heated bed. Turning the wall plug 180 degrees (that's possible with dutch wall plugs) There wasn't any current on the heated bed anymore. Problem solved?
No not really. First of all I don't want to pull out my volt meter every time when I plug my printer into the wall socket to see if I have to turn the plug to not get electrocuted. Secondly I think it is strange that the heated bed itself gets current. I would expect that only the heating element in the rubber mat beneath it should get current.
By the way, even when the heated bed is electrically completely isolated from the printer but only connected with the wires of the heated bed to the control unit the tingling occurs.
Hi! I appreciate very much your work and your passion, I make this improvement too and I have to ask something else: in my opinion the y-axis stepper motor is undersized for the structure and weight that have to move and often with hours and hours of printing, can you make a tutorial for substitute it and the needed vref modification ? Or at last which motor can you suggest me/us for that improvement? Thanks!!!
Nexi, tks a lot for the help you provide with your videos. A few month ago i made the same improvement on my CR-.10, following your steps. Now, I am thinking about improving my printer with one of those boards, the Duet wifi. Can you help me with this? I manage to do some tecnical things but i dont think i have the knoledge to do something like this. I wold like to install the duet wifi and preserve this bed heating system on my printer. Do you know if it is possible to do this or do you sugest other way to get 32 bits working on the printer? Tks a lot. Love your work.
Great Video!! Keep em coming
While the idea of this upgrade is a good one and improves the operation of the 3D printer quite significantly and you look like your quite capable in what your doing, it is not a safe implementation for the following reasons
1 Your connector on the back of the case will expose 220V if the plug is not connected, this is a NO NO.
2 There is no fuse in the circuit, most countries dont have a fuse in the plug, you really should have one.
3 The frame of the 3D printer or at least the bed should be grounded, just in case of a fault occurring.
4 I am not sure of cutting holes in those heat mats is a good idea, you can easily expose the mains powered wiring inside or even cut it altogether making the mat useless.
5 Using the same color wiring as the 12V system in the case can cause someone going in their later to think it is the same voltage as every thing else aka 12V and you know what that can mean....
6 The plug and socket is not rated for 220V as another viewer has mentioned.
7 Not using correct termination techniques on the wiring is not a good practice, stuffing the wire under the spade terminal is just bad. you should crimp on additional spade terminals to do the job properly.
8 Not enough warning to viewers who may attempt to copy this upgrade was given, this can be extremely dangerous if performed by an inexperienced person.
Peter Oakes
1) I don't see any reason why would be somebody who is done this upgrade ever screw out safety ring in the plug and then disconnect the plug and stick finger on pins in plug (220V) when printer is on?
2) Yes, there is fuse in the sistem inside main AC plug and powersupply and the solid state relay is connected to it. it's 10A rated (10x220V is 2200W so it's fine).
3) If AC heater silicone pad ever catch short circuit fuse(AC) in control box will burn out and cut AC main voltage (small chance that AC heater will ever get damaged because of much lower temps that CR10/S will ever use sense is 135 max in firmware and 260C is max rated temps for AC silicon heater.
3. There is no point to ground the whole frame sense heated bed is isolated from printer frame(Plastic on rollers bearings) but I can agree that extra safety is always welcomed so adding extra ground wire is good idea and I might do follow up video.
4. I didn't cut or drill any holes on AC heater(am not crazy) holes are already pre cut and made by manufacturer. This silicon heater is made for CR10/S and have holes on right place.
5. And other AC wires in the control box, power supply and on AC switch and fuse are what color? The are the same red and black... Look again. All wires colors on AC and DC was the same color even before this upgrade.
6. I can't agreed on this one because amps that going though the connector now is 3.4A and before was 18A that's way less heat and stress on this plug then before.
7. I pull every wire hard to make sure they will not fall out. It's holding very strong. Adding two spade terminal on single screw will luckily be ever worse because of bulky plastic insulation on the spade terminals can push each other out or not be able to hold strong as is now..
8 Ok I will will add disclaimer in video description and on video that this can be dangerous if performs of unskilled and inexperienced person who don't know that AC voltage can be dangerous.
9. Only thing I can see that may be issue here is the paper clamps and I don't like them near AC heated and I recommend installation of ANYCUBIC ULTRABASE and no longer paper clamps. I will add that in description and on video.
Hi there, I appreciate the response and clarification for many of the points I raised, some of which are based on a general view rather than country specific (I did not see what plug you were using for instance, most countries do not have fuses in plugs (UK is the only one I am sure of)
So in rebuttal to your rebuttal (All Good I assure you)
1. Doing it for your self is your risk, but others may copy and either way it is not a recommended way of wiring mains (That's why sockets are on the wall and plugs are on the appliance :)
2. Good to know but my point is still valid for countries where this is not so.
3. yes, with fuse in place, this is ok
4. Good to hear, I have a pad exactly like this but without the holes, I was not aware you had one special for your printer
5. It is good to know your not making the wiring worse but it is bad in the first place when these are not clearly distinguished from low volts and mains, this is not your doing for sure, it is the manufacturer, but if I was in there doing this, I would have taken the time to improve things. You certainly did not make them any worse so that;'s good.,
6. Yes, you have significantly improved the current load through the connector but it also has a voltage rating, this is what is now being exceeded, this may be fine for years but it is things like the insulation breakdown, the clearance between pins etc that is now being violated based on codes etc. Will it work, sure but is it to code.. probably not.
8. Excellent, thank you.
9. I did not raise that point but it is a good thing to mention and fix.
To clarify and on the positive side, I do feel you made a great video and it is a good upgrade, my feedback is only intended to help people who may follow in your foot steps but with lesser understanding or skills, when I make my videos this is something I always try to cover when dealing with mains especially, here in Canada i have the drawback of only having 110V mains, yes less volts but twice the current to make up for it for the same power so wiring always has to be so much thinker, just one of the things I miss from living in the UK :)
You are right - a more appropriate work around with the socket would be to use separate, soldered, lower gauge (for safety) cables for the 220v, eg. drill a hole in the side of the box to accommodate this with added 220/120v fuse coupler. 750w through that gauge of cable concerns me more than anything, the cable under load will heat up with the current demand and if the connector does not have a perfect connection, the connector will physically heat up due to the resistance. Can it (the cable harness) handle it - yeah for short bursts but a constant long term load will (should) heat up the harness eventually. The exposed soldered terminals on the connector should at least be shrink wrapped with glue impregnated wrap in case the connector gets bent and you have a short (look out!). The tape over the spliced wires is bad. Another location to use electrical shrink wrap ...just some thoughts.... This video does at least show how to approach this installation properly enough though.
There is nothing wrong with the connector. I been test it with 30+ hour print with heat-bed ON and I monitor everything with thermal camera and it was no heat and no issues and then I upload this video.
Right now It have over 120 hours on this setup and all of them is with heat bed ON. Again no heat, no issues. And connector is on metal case that is also huge heat sink in some way...
About the tape on the socket no: I used white insulation tape to get extra safety but if you look at 5:45 there is plastic insulation ring covering whole connector. Over connection there is safety ring and there is no way that this connector ever have bad connection..
Now about the power(amps) going through the connector. If you do calculation in amps on the connector. Before it was 18A x 12V =~220W now is 3.4A x220W =~ 750W that's 5.2 times less stress in amps on the connector. And there is again no heat ever that i found in my testing with the help of thermal camera and with one more infra red temp sensor and with my hand.
Why would I use thinner wires on 220V when there is a fuse in control box on 220V? Power-supply and Solid state relay is connected to that fuse. Its 10A fuse 10A x 220V = 2200W. Thin wires will add more stress and more heat to the system.
And if you guys ever want to do this upgrade then please do it in your way and use this video as idea or reference how to do it or at least just for compering results etc heat up time...
P.S.
I add disclaimer in video description.
The problem is that it's possible, and Murphy tells us that anything that is possible will happen. One day the heating will stop working for some reason, diagnosing starts, people might die.
For anyone wanting to know, I was able to do this with a CR10 S5! Just keep in mind when connecting the SSR to the motherboard to connect the negative side to where the small black cable from the heating bed port and the positive side to where the red cable was on the motherboard. I also couldn't get the end off of the cable so I just saudered the original cable with the new one. Works pretty good but doesn't look great lol. Thanks for this video too! 😊
What do you mean? Your comment is unclear. According to the video, the ports 3 and 4 on the ssr go to the mainboard.. are you saying to ensure each one is lined up with the -/+ on the board as it is shown on the ssr?
great video. you are a genius maker. thanks.
You are awesome, thanks so much. You deserved more views and subs.
Thank you so much! :)
Sweet upgrade😁
Very nice video and very informative. I was wondering if anything had to be done to the firmware to make this work?
Excellent explanation and simple to understand. I have not much electrical background. WOuld like to understand, why we don't use MOS FET, but rather go with AC SSR? The original heater was heated by 12V voltage, but the new bed is heated by 240V voltage. The existing mosfet is not designed to handle that voltage or what? Also using 240V to heat the heatbed, not dangerous? Like a shortcircuit or so? What about using a fuse or two in the setup? And the last one, what if SSR stops switching even the current stops on the input side? It will continue passing 240V across the silicone heater. As a protection we can have two SSRs lined up in series to avoid this functionality problem? Because in original heater, even the heater is on continuously it does not go abot 110-115 degree, at least in my case. But it this modified case it will. Again, I don't have electrical background, but just trying to understand?
Just did this upgrade on my cr-10s. Thanks so much for the awesome tutorial.
I was thinking of getting the tevo tornado because of its ac heat bed but now i don't have to!
So to fix all the issues people have highlighted:
1, replace the aviation connector with a reverse 5pin 250v rated one, so no ac exposed back of control unit
2, run a ground wire on the extra pin to the aluminum plate
3, put a 5amp inline fuse before the relay
4, use spade connectors to connect to PSU AC and relay.
Does that about cover it.
Curious how did you attach the ground to the bed? Have a link to the connector you used ?
Thank you for the note, very helpful.
@@LCSRacing there is no good or up to code way to do that, so these mods are always dodgy
Best possible would be another countersunk hole but thats not possible with the silicone mat.
Workaround is applying a counter nut on one of the screws and having a ring terminal with counternut below the leveling knob. (but this needs to be undone every time you twist it)
@@anxiousmerchant4129 You don't really need to ground the heated bed directly. You just ground the mount plate underneath. Be worth checking resistance between the two before you count on it but it should be fine.
@@uglyduckling81 On most printers the bed carrier is isolated form the bed and electrical contact is coincidental if a screw touches the hole wall
ofcourse you have to ground the plate directly. If you give electrical advice on the internet, do it factual correct or be silent
If the diy'ed contraption misfunctions and safety fails, guess who's liable
@@anxiousmerchant4129 no one is going to go hold you liable for a dumb youtube comment.
hello nexi
nice tutorial, thank you
i am doing the upgrade
but i am doing the cables myself
since my heated bed came like yours
with almost same wire colors
my AC cables are both red
and the thermistor cable is black
with 2 cables , 1 red and 1 black
how do i know whats the + and the - AC cable?
i think for the thermistor it does not matter
just let me know
thank you
great !! i do on my CR10S
and all it's ok! TANKSS
Great intro
perfect video just tune the PID of the bed!
Thank you! I might do that to make even better.
Another great video on upgrades, Nexi clean crisp and to the point...Best Regards buddy and Happy Extruding !
The Happy Extruder Thanks buddy!
Best Regards(Extruding) :)

@Nexi Tech Hey mate, I am planning to use an EZABL device in combination with the Keenovo 1000w AC heater. I read on th3d website that 'cheaper' SSRs 'leak' current and therefor mess with the accuracy of the device. Do you use an EZABL? And if so which SSR do you use for that?
Great job, thank you. Are you aware of a 110VAC heater for US users?
Nice video! Also I love your intro animation
Theo Stephen Thanks :)
Dude...this is the most complete video I've found so far. I was wondering about the thermistor and connections to the plug.
Great work.
UPDAET:
HOT DIGGITY DAMN, it works! About to do a PID test but the bed works!
Thanks for sharing this with such clear and easy to understand detail. I see a lot of negative comments from the peanut gallery, but such is the way with youtube... Bunch of professional keyboard critics lacking in the testicular fortitude or electrical experience to do what you have done, nothing more. I for one appreciate your work, clean work space, clearly worded instructions, and well put together piece of education. Happy printing!
Very nice instruction video. May I ask, why are you sticking the Silicon Heater on the old heater? Thanks for sharing.
The original heater is very thin, and there's no obvious way to remove it!
v2.1 board requires you to use the "Hot Bed" connectors on the board. These are the two connectors that the wire from the mosfet run to.
This helped. I worked for the 2.0 as well. Not sure if it's because I updated firmware.
The wiring etc here for the heated bed is it the same for the X5S. I have ordered everything from your X5S upgrade list as well as the printer but want to make sure that I am understanding this particular area of the wiring. I ordered the mosfet as well but looks like its not necessary Thanks
The upgrade works awesomely
Is your bed still working? Any problems?
@@TheRainHarvester Yes it still works perfectly.
@@trevorlynch6549 thank you!
I'm trying to build a diy 12x12" , but finding a 12v heated bed seems impossible. I only have 110v wall outlets. I'm not sure if I could use an adapter. Also the bigger heat beds are 750w!! That would heat my room!!
@@TheRainHarvester There is a 120v option on the link that he shares in the description. There is no plug you wire it up to a relay to control temperature.
@@trevorlynch6549 yes, but the relay relays the required 220v. So I was wondering if connecting that 220v relay input, to a 110v plug that goes to a 110v-to-220v-adapter would work.
Hi Nexi!
Great idea. Love it! And going to do the same! But there is a quesion: after upgrading heat bed time for bed plate upgrade :) So what do you recommend? Glass, mirror, LokBild? Please keep in mind that having a opportunity to head a bed to higher temperature there is possibility to finally use ABS etc.. Have you ever concerned turning your plate into magnetic one? Is that possible with high temperature without loosing neodimium strength?Which magnets to choose for that bed upgrade?? Another problem is isolation cotton which decrease magnet's power (so in that case should use again bigger and stronger).I've seen that people used to stick it on the bottom, but how to glue it to cotton :)? Any idea regarding perfect bed for that upgrade?
Hi Nexi!
It's been a little while .. but finally I have done it! :) In big shortcut: your idea but with my personal improvements such as:
-LokBild,
-0,5mm alloy sheet (previosuly I have bought very expensive spring steel! which doesn't affect magnets :)))) - so any of you whos wondering - don't make my mistake ;)
-added another aluminium 4mm cnc drilled sheet as base for magnets as well as heated top platform,
-special 60pcs magnets (which are fine till 380 C degree),
- instead of 1 isolation cotton sheet, I have used 3 of them (it was solled in pack of 4..), but 3 here are important in my design- it prevent thermister and heater from smashing and squishing ),
-bottom platform I have left orginal one as support for cotton which isn't glued,
-each wires were equipped in connector,
-I have left orginal lenght of new calbes (never knows when it might be needed)
-Lenght of screws 4x50 or 55 works better (60mm might be too long).
Pros:
-It's work like a charm! :) Always wanted to have such possibility.
-heating bad to 60C - after improving time drasticly droped from 15-18min to 1 min 10sec in my case! 15 tmes faster! Madness!
-Despite the fact than somebody has described that metod as "unsafety" a few times, calling others idiots and other unpleasent words.. As long as I exactly know what i'm doing - I hardly believe it's pretty safe! Person who disagree, seems has a lack of knowledge or experience... ?
-Availability to print immidiatelly after turning on printer, which is really cool!
-Possibility of using other materials (those which require high temperature).
Cons:
-It not a cheap modification (especially if you own S4 or S5) -approximately it costed me somewhere around half of S4 :) Sick! :)) But I don't regret!
-On your film all job took a few minutes - in my case I've losted a half day (got more tasks to complete )
-Despite the fact that bad is immidiately heated up it's good practice to give it another minute or two to heat bad evenly.
Thank you for sharing your mod!
Great stuff...watched it several time and ordered the new heat bed and relay but when using your link to the insulation material you glued to heater. Were finding it's unavailable. What are the white squares made up off? Is there a substitute? Does it need to be some fire retardant material etc.?? Hope you can reply will keep checking back as we wait for our parts. Thanks a million I have been wanting to do this and with your video decided we could thank again!
Hi Rob! Im glad that I can help and that you found mu video useful. That is heat resistant cotton which can withstand very high temperature without releasing any toxic fumes in the room. I just updated all links in the video description, please check them again. Just one tip you can use also silicone glue to hold the cotton it in the place. Remember it takes time to cure. Cheers!
Thanks for your video.
Just one thing. At 8:40 in this video you connecting wires in to heater0 in the middle it was wrong for me. It was start working when connect them to heated bed first two beside.
Thanks
Yes I found exactly the same on my CR10-S. The heatbed relay wires need to be connected to the two terminals at the bottom of that connector block as shown on the video. It is is extremely important that the polarity of the wires is correct or the relay will not function.
Otherwise a flawless video and many thanks!!!
Then make sure you EARTH/GROUND your Heatbed and Printer Frame to EARTH/GROUND running an EARTH/GROUND Cable to the the correct connection inside your 3D Printer's PSU.
I followed a guide on the TEVO Tornado on how to make it safer/grounding/earthing. Please use Google or TH-cam.
This is an extremely important safety feature and if you are going to all this trouble to upgrade your 3D printer, PLEASE DO THIS AT YOUR EARLIEST CONVENIENCE!
Thanks

I installed a 24V 500W silicon heater. I also installed a circuit to isolate the 24V from the printer using an optocoupler. I later found out that this is NOT NEEDED, because the CR-10S already has one on its MOSFET module... DANG.
The bed heats up much faster now, BUT because of the thermal characteristics of the whole bed (heater, glue, aluminum, air, glass) there is a lag in the heating of the glass itself.
When I heat up to 90c the glass is just at 70 and takes about 3 minutes to reach the temperature measured at the NTC. Take this into consideration people...
Everything has a 'thermal constant', i.e. it's ability to conduct heat. Plastic has a very high thermal constant. Aluminium and brass have a very low thermal constant. Glass is somewhere in between.
New intro, nice👍
Karlson Chee Thank you
Will this work with the CR10-5S ? I bought a 500mmx500mm version of what you show and it comes with it's own temp control, but it's WAY off... like 10C off and the heater doesn't kick on until it's almost 20C below where I set it (in this case 70C). Right now I have the factory bed heater plugged in because it won't run without it plugged in. I just quickly tune the bed for the project to 0C so it doesn't heat up. But super janky set up. I want to do it your way, but am not an electrical engineer. I just need to know what parts to get. and then your instructions for set up seem pretty straight forward.
The SSR DC input is polarized. You need to make sure it is connected correctly or it won't work.
Muito obrigado, funcionou muito bem, acredito que pessoas como você vieram ao mundo pra fazer o bem, fique com Deus, e muito obrigado.
Hey, this is awesome! Could you make a video where you´re printing ABS or Nylon. It would be really nice, to check the quality of the print.
You still need an enclosure really. This is a great step though. Keeps everything toasty.
After reading all the comments and reviewing the video I have to agree with the gang on one this, GROUND THE FRAME> I am an Electrical Engineer and that is the only way to be safe. The rest of the set up looks fair. Just run a ground to the frame and into the control box and ground to the input power ground. that should make it safe. Great video and I plan to do this in 120v as soon as I get my CR10s next week. Thanks for posting.
morgoth62 Thanks man I agree on the ground wire and I already wrote it my "pin comment" right after posting this video on extra safety. Recently I install this upgrade on my Tronxy X5SA and it's works great as well. I will post video on that soon when I finish with other upgrades. Still waiting for some parts to arrive.
Regards
Nexi
great job thanks for the video
No problem. Thanks for stopping by.
He is a genius!
:D
Knowing my electrician skills, I'd probably goof this thing up at every step.
Is there a (relatively low cost) printer model that comes fully equiped out of the box to print nylon and polycarbonate ?
Just did this, worked great. Clean install. Don't listen to these guys that say this is dangerous, the cr10 bed underside is potted and isolated from the bare aluminium, it won't conduct. The only time the you'll get shocked by the bare connector is if you have the machine on, running bed temperature command and have the connector disconnected.... don't ever see that happening.
Great Guide, I cant quite make out where you have connected the 2 wires that control the relay on and off. Can I connect it to the same place where the 2 small wires from the heater bed moffet connected to on the motherboard? This is also where 40mm fan that cools the mother board is located.
Fluke752 Yes that's right. Where two wires(heat bed) connect to mosfet. You can use that two wires just cut conector and connect them to relay.
Great video bud, one question though. Where should I connect the cables from the SSR's control side? Should I connect it to where the motherboard connects to the MOSFET (removing the mosfet connections too)? Do I need to change anything in the firmware as well? I have version 2.0 of the Creality motherboard and the connections in the video don't match up (the 3rd and 4th screw down connections on the motherboard are connected to the extruder on my board). Thank you!
Matthew Moorhead Yes, SSR control you should connect on the motherboard where the heatbed or heatbed mosfet is connected to. You can use same wires from mosfet just cut them if they are long enough. No you don't need to change anything in firmware for this upgrade to work. Regards

Hi friends. This a DIY guide. If you don't feel comfortable, then don't do it. But stop criticizing the author. This is a very good example of what TH-cam can do for you. It can help you improve the product you've bought.
I'm a qualified electronics technician and I usually don't work with more than 48 V AC or DC, but I'm not afraid of 230 VAC. I know how to it make it safe for my kids and my wife (maybe not for my wife - she's got a good insurance).
Please use your common sense.
For roughly 25% more money, you can buy the same Keenovo heat bed that has it's own external controller. This eliminates having to connect it to the CR10 control box if you are not very comfortable with wiring. You will still have to de-solder the old heat bed though.
Why not, that's good idea. I will place that option in video description as well. Thanks
Another great video :)
Thank you ;)
it's great except... that upgrade isn't cheap by any means.... but it is awesome = ) thanks for the video
True, but it helps so much with ABS prints. You welcome :)
It's cheaper than the alternative... Which is, if you want to print ABS, selling your cr10 and buying another printer that can get to 110C.
If you havent done so already, you should make a video on ways to make your printer more safe. Something on the lines of how people make tevo tornados safer.
Great video as always, but is that connector on the black cable to the heated bed rated for mains voltage?
Yep, my question exactly. But I think that it should be enough.
It's not a problem because load in amps is way to lower then before upgrade. Before was 20A on the connector and now is 3.4A
Steven Bacon Also there seems to be a metal outer sleeve just separated from mains wire by a layer of tape/small gap. If plug were damaged eg crushed or dropped then there's the possibility of it going live. While it may work I don't think I'd personally risk doing this mod. Any faults with the wiring could result in a live plate/frame which is afaik unearthed. If you are tempted by this mod, consult a qualified electrician.
freeyourinnertube If you pause video and look close on 3:59 you can see that tape is just extra protection over plastic cover. That plastic part is inside of plug and I add tape just to get extra safety.
Nexi Tech Hi. I saw the tube on disassembly. On reassembly at 5:45 you mention it but you don't see it being replaced. I like your channel but worry about this upgrade as it has the potential to go seriously wrong. As shown you don't use upgraded connectors, (cables, and power supply), the chasis isn't earthed, and the heated bed is only protected by the appliance fuse, a smaller fuse could be added for the heated bed alone. Ive done a number of printer mods that you've done, but will not be going near this one.
Awesome video!
I know you are looking into doing the same thing with your TRONXY X5SA and since you have both these machines, what heating element would you recommend for the TRONXY X5SA?
Can wait for the TRONXY heatbed upgrade; need to order parts before mine gets here.
Thanks man!
The Looking Glass Thanks man! Well at the beginning I was thinking to go only with 12V 30A heatbed mosfet and insulation for my Tronxy X5SA but power is not enough. I measure only 17.5A(210W) pull from the 30A mosfet and 30A power supply and that's because of 0.8ohm resistance of the heated bed. Not quite enough. Then I was thinking to add one more 12V power supply or replace it by 24V powersupply and run whole printer or heated bed only on 24V. In that case Heatbed would pull around 30A (700w) but then we need to replace heatbed 16Awg wires with 12Awg silicone wires add one more 12V or 24V powersupply, we need Heat-sinks for borh power-supply as they would run at maximum power when heatbed is on and 24V heatbed mosfet. I think I might go with AC 600W-750W silicone heater and SSR as it's much simplier to install and possibly cheaper.
P.S. You have all Tronxy X5SA upgrade parts listed under It's review video.
Cool! I too think that going with 220Vac is the best, cheapest and above all safest way to go. All I need to find now if the largest heat mat I can find.
That´s where my question comes in: what is the CD of the holes on the TRONXY bed? Will also ask in the forum see if anybody knows.
It would be a good idea to heatshrink the AC terminal in the plug. An earth for the bed would also be a good idea.
I agree. Why not it can only be better. Ground can be added on one level adjusting screw for example.
@Nexi Tech Can I use same parts(relay etc) as you did with a 1000w heater? Thanks for the great video!
aerospaceTUdelft Yes you can. You welcome mate! :)
You are awesome!
Really great video, very good detail :) I'm looking for a high quality version for the CR10 S5, can you point me in the right direction please??
Thank you, Yes sure, have look on my CR10 Max review - th-cam.com/video/lE9i1-DX1aI/w-d-xo.html
