SKR Mini E3 - The best Ender 3 upgrade from stock?
ฝัง
- เผยแพร่เมื่อ 11 พ.ค. 2024
- I’ve made videos on Ender 3 mainboard upgrades, but this one has been highly requested. The SKR Mini E3 from Bigtreetech is a drop in replacement board that also comes with pre-made firmware. For the price, I consider this incredible value. Mine had one hitch but my free firmware files below will prevent that happening to you.
This upgrade is so great because:
It negates the need to spend time, effort and money on a bootloader.
It updates your printer to the newest Marlin with all safety features enabled.
It has a more powerful 32bit processor
It is more exapandle: No pin27 board needed for BLtouch and support for touch screens, UPS and PSU relays.
Integrated TMC2209s mean no more zebra stripes and no need to spend money on TL smoothers
TMC2209s mean much quieter, no need to spend money on stepper dampers
Plug and plug plus affordable
One thing I should add is that you can switch between stealthchop and spreadcycle by simply switching a jumper.
These boards were sent to me free of charge for the purpose of making this video. I also ordered the same set of three boards with my own money, but these ones came first. All opinions expressed are my own.

Michael, Thanks a million. I assembled my Ender 3 and was up and running in a matter of hours thanks to your videos. I think that the SRK mini 1.3 will be the next upgrade as it solves all the issues that I intended to fix on my 3d printer. One of the features that I liked about the SRK mini was the addition of the BL Touch without the need to cut wires. Great video. Keep the content coming!
-Michael
I received my Mini E3 two days ago and even before I had time to try to install it you posted this video. Thank you very much!!! It will be much easier now.
Awesome, thanks man! I just ordered my Ender 3 last week after the engineering company I was at bought one. Me and the coworker in the design department spent around two weeks playing around with it. I also watched most of your videos regarding it in addition to the other major 3d printing youtubers so I think I´m set and confident. This is a really cool addition that saves me a lot of trouble, I´m lucky I saw it.
you are the best dude, ty so much for all the hard work you do. my ender 3 experience would not be the same without you!
You never cease to amaze me, Michael.
I will get my hands on those for my print farm.
You're one of the greatests assets of the community.
ohh my god... so i jumped the gun thanks to your video, you are NOT KIDDING about with the noise difference, i actually giggled like a school girl, i cant get over how quiet it is...!
Just received mine, a v1.2 board. Only 2 weeks from order to delivery in UK. I followed your instructions and was up and working inside of 30 mins. I'm really enjoying the near silence and so far print quality seems noticeably better. Really great instructional video (like all of your content), thanks very much Michael.
Thank you for the precompiled upgraded version. I have one of these boards and a stock ender 3 waiting just haven't had time. now i can throw it all in under 10 min. i have the skr pro, and the skr 1.3 boards both with 2130's in my other printers. love the boards and stealthchop 2. great video as usual.
So let's talk about the duck. It's actually a programmer's friend. Whenever you're trying to fix a bug and can't seem to find the problem, you talk it out to the duck. If it's a difficult or persistent issue, you gather a council of ducks to work on the problem. Since talking out the issue often helps, and a rubber ducky will never get horribly confused or bored, this little ducky can be your helper friend. If all else fails, you have something squishy to hurl across the room.
Thanks Michael, I was going to buy the SKR 1.3 but kept putting it off. Now thanks to your video I have just ordered the E3 board. Your channel is an asset to our community. Cheers mate
Curious if you'll get it soon .. the AliExpress store (official BigTree) just updated that they're having supply issues with the 2209 and won't ship until mid-October.
My sentiments also :)
kylek29 Have been told 9 days
But we will see.
Received mine today 9th Oct,
First of all - thank you so much!
Recommendation and tutorial are great.
This is literally the best upgrade I've done to my Ender3. I've installed SKR 1.3 alongside with Noctua fans, and boom - it's now so quiet, I could print in the bedroom at night if I wanted to.
II just outfitted my printer with this board and I cannot believe how much quieter it has made the motors. I was a little skeptical but very willing to make the printer quieter, as its set up in my bedroom, and I could not be happier about the result! Thank you SO much for this guide.
You got the sub when I saw the Ayrton Senna jacket! This tutorial is awesome!
Thanks Michael. Great video! I've learned a lot watching your videos along with others. I've had my Ender 3 for over a year now and have made many upgrades.
When I found this video I had a SKR E3 DIP on the way with tmc2208 setup for UART. I was wondering if you're planning on doing a video about the DIP board with UART setup. If so, great. If not, I'm sure I'll be able to get it setup without much trouble. Thanks.
This is an excellent video. I just installed my new board and am amazed at how quiet it is. Thank you for such a descriptive explanation!
Going to have to look In to this. Great job as always Michael!
Great video. I'd love to see this in a Tarantula Pro. I might order one.
The perfect gateway drug into serious upgrades
What would those be?
Bought this board along with a BLTouch as my first hardware-related upgrades to my printer. The diagrams were very useful for the swap, I appreciate it
Thank you SO Much Michael. I've just recently purchased a SKR Mini E3 V1.2 Board as i was recommended to buy it over the upgraded Creality 1.1.5 Silent Board and just Wow. I'm so happy that I'm now able to use my Bltouch and My old Z end stop as a filament run out sensor both at the same time thanks to your excellent programming of the firmware and the fact that this board has a 32 bit processor and loads more space than the creality one.
thank you once again for all the time your have taken to get this right for the people who with use it and thank you for releasing your version of the BTT Firmware Pre Compiled it has really helped me get off to an amazing start with this new board. KUDOS to you my friend and well deserved at that.
keep up the excellent work because you don't get enough credit for what you are doing
That’s a badass hoodie right there.
The ONLY reason I am pondering making this upgrade is because my printer is working so absolutely brilliantly as a result of all the other changes I have made from Michael's Videos I just don't want to go one tiny step backwards. Literally from the test cube I have from my first print, to now is night and day different. My latest cube almost resembles an injection molded model!! You are changing the game Michael, please keep them coming. (I will undoubtedly do more).
Thanks buddy that is extremely kind. Glad to hear your printer is doing so well.
Teaching Tech question whilst I have you.... any chance you can share your test print ‘X’ looked for something similar on thingiverse but couldn’t find anything. Assume I could make something easy but if you’re willing to share, thought I’d ask.
I just installed this board in your rear enclosure and wow, so far very impressive and I love how the printer looks with everything in the back. It is so quiet now I notice the fan noise so much more! One thing I did notice is that when installing the mini E3 in your enclosure my z stop wire is just barely long enough. in fact I had to bend the pins a little on the switch to ease some tension. I might see if I can buy a slightly longer cable or just simply cut and extend this one. Thanks for your enclosure design and your videos!
Thanks Michael! I ordered 3 Mini E3 boards and it took 13 day to get them to Tennessee USA (Late October 2019.) Followed your instructions and all went well.
Finally the upgrade I have been wanting for. This one looks EASY! 😀
Great! Was looking for this video to be made! :-)
Awesome. I've been putting off ordering the skr 1.3 then came this board with little information. Seems straight forward. Will order today
thank you for your videos. thanks to them i took a dive, ordered skr mini, put it in my ender 3 in place of stock mainboard, using your wiring diagrams, and everything works perfectly from the get-go. this is my first 3d printer and without your videos i'd probably keep being afraid of upgrading.
Next you need to do a tutorial for installing auto-leveling sensors on the mini E3
Welp, with that review I'm in for one. And a BLTouch.
Same, ordered it right after:)
I haven't even received my e3pro but after hearing the difference in noise I might just order one of these boards immediately XD love all your videos super helpful!
First off, thanks. Awesome tutorial. Second, not sure if anyone else had the same experience as I did but in performing the board swap-over just now, every single one of my connections on the original Creality board were hot glued into place. Took way longer than 15min... but works like a dream now.
Definitely puts the Creality upgrade board to shame. By far the better value offer.
I know right?
When I saw that they charge you over $50 just for stepper motor IC upgrade I immediatelly ignored it.
They should sell it without trying to make a profit, they already made a profit on the sale of the printer.
@@Arek_R. No, they can make a profit. Just a reasonable one, in relation to the price of the printer. The Creality products just offer too little value and features for the price compared to the competition.
Like, when they try to sell some bog standard cheap spatulas as "special print removal tools" for over $30 for a set of 3.
Sure, quality is an important factor, but in the end, it's all made in China.
Installed the SKR E3 Mini on my Ender 3 Pro over the weekend. Can't believe it's so quiet!! Thank you Michael for this vid and your diagrams. Can you now please do a vid on adding BL Touch and filament run-out sensor to this new version (1.3) of the board?
Did you ever have any luck? I'm stuck!
@@craigstannard3391 I didn't get round to it, to much to print ;) Just got a 2nd E3P and am in the process of building it. I might try adding the BLT to it as I build.
@@tlclstuff cool. Thanks for the response!
Ordered shortly after this video was posted. Just got my board today & finished installing it.
HOLY CRAP! Virtually zero stepper motor noise!! *Very* satisfying, if a bit unusual after hearing stepper motor noise for dozens and dozens of hours. Easy swap, came with Marlin 2.0 bugfix right out of the box, prints perfectly with no tweaks.
Looking forward to trying linear advance and some of the other things I couldn't previously use.
Thank very much you Michael, this ill be one of the most valuable videos for a lot of newbies that wanna upgrade the board. Looking forward to see what you gonna do with the other skr board. :)
Could you make a marlin 2.0 in depth tutorial for the Ender 3 SKR Mini E3 board?
have you ever found one?
Great video, finally I think it's worth upgrading my Ender 3.
Can you please make video of you adding *TFT35 V2.0* display to it?
It's available on their store.
i have to say im not all that impressed with the Screen they do, its literally plug and play in to the TFT marked headers , no firmware changes or anything which is great for ease of use, but theres a few problems ive had which ill get in to later...
from what i understand (forgive me if i get this wrong then feel free to correct me) it seems to piggy back on the serial connection as if it was plugged in to the USB port. here lies my first conflicts with the screen and octoprint which again ill get in to soon.
if you've used octoprint (who dosent..?) you know the annoyance of trying to cancel a print or change temperature while its pre-heating, either you wait a few mins depending on your material and temperatures or you switch it of at the plug and back on if your home/by it. if you try and change the temperature while its heating up you cant! you have to wait till its finished heating up before you change or use the STOCK LCD with your printer.
so.. same deal, the printer sends the same busy commands too the TFT locking it out of any changes at all until its finished heating, of coruce you can use the m108/EMERGENCY_PARSER commands with octoprint but the e3 mini firmware screams at me if i try and enable this saying its not supported yet, and there dosent seem to be a easy way of adding these to the TFT firmware Evan if i had it enabled, but i could be wrong..
another annoying thing i've bumped in to twice now in my few weeks of owner ship is that because the TFT seems to share the same serial as octoprint, i've had octoprint error out of my a few times just disconnecting saying something along the lines of "timeout" "too many connections" again not exactly what is said but my memory is shot today hah,
and the layout is kinda boring and poor for a COLOR screen
now don't get me wrong its very handy for changing a temperature quickly if you want to do some testing before a print or to change it AFTER heat up, but for the time in between when you think "oh crap wrong temperature" you find your self having to use the stock screen, so then your left with using both, probably not the upgrade solution others and me included was expecting
so to summarize
seems to share this serial connection the screen also has the same limitations
seems to conflict with octoprint causing disconnects and then failed/unfinished prints
poor layout and use of a color screen
and i am i no way trying to say its crap, as the main board it bloody amazing, but the screen.. eh.. i dunno id stay away from it, maybe instead get your self a screen for your PI and set up touch UI for octoprint, and have a much better UI experience and hopefully no serial conflicts, i mean you probably have your pi right next to the printer anyway right?..
i think that's the route i'm going to take next..
Probably not worth it, the board is a literal nightmare to install due to the lack of documentation and photos. The support staff seem helpful, but for something that's allegedly plug and play, it's way too hard to get working. Having proper photos of the board with the relevant wires rather than a wiring diagram would go miles towards making the process real. As would having real documentation about how the firmware is supposed to work, including video of the procedure as it's far more difficult than just loading the firmware onto an SD card and powering on the machine.
Yer a good teacher. You explain alot of technical things in a very user friendly way. Were someone is up on all the technical terms and components and your still able to understand and grasp what is needed to be done and how it all works.not an easy task.
I installed the SKR Mini E3 1.2 into my E3 Pro. Works ok. Needs tuning and needs a new Marlin build that includes Mesh manual bed leveling. Now trying to learn VS code and platform IO without success so far. But I am new to all this. Thanks for all the great content!
I just bought a a Creality 1.1.4 board a month ago, and I'm going to buy this right now.
Same here. But a shame the SKR isn't available right now. It's a 'Pre-purchase' for when they're manufactured due to a shortage of 2209 stepper driver IC's.
The best and most intelligent channel for 3D printers. Thank you very much.
no - just no. Tom Sanladerer, CNC Kitchen, Tech2C, ....
Hi Michael, nicely done and well structured video. ✨😃
Looks like they won't be shipping any until at least mid-September due to a shortage of 2209's. I will definitely pick one up, I had been researching it before this video so perfect timing!
Some FAQs from the comments:
1. -There are notes in the github about having to emulate EEPROM for this board with a file on the SD card. When compiling from Marlin 2.0, I only uncommented auto init eeprom and it worked without any problems. It made it's own EEPROM.DAT file on the sd card. EEPROM is verified working for me. Only downside is having to have the SD card in when you boot or try to save settings.-
UPDATE: Thanks to my Patron Glen Roe for keeping me up to date. Marlin 2.0 has now been patched to avoid the need for the EEPROM data to be stored on the SD card. All of the downloads above been updated.
2. There are a few spare pins free for things like filament runout sensor, plus dedicated ports for RGB LED. It also support the new BIQU TFT24 touch screen. I plan to make a follow up covering these.
3. This board connects like usual to Octoprint or PC via USB.
4. If you've already upgraded to the SKR V1.3, don't despair! It's a more powerful board with more extend-ability. Only real downside is needing to print new case to fit it.
5. I purchased the Senna hoodie at the Aus GP this year. I'm sorry but I don't have an online link :)
Could you post the Configuration.h and Configuration_adv.h files too? You have a great base line to work off of!
@@lexus30 All already in the description.
Teaching Tech I completely missed it! Thank you sir!
I notice an EEPRoM.DAT file is created on the SD, so the FW must be using the SD as virtual EEPROM.
You might want to pin this :p
You forgot to mention that the board will be available at mid October because there is a shortage at stepper drivers TMC2209
Thanks for the info on the SKR mini E3. I just built my Ender 3, and the board that came with it had a bad Z axis driver. So there is a SKR mini E3 on the way.
Thanks for this video Wow what happened to my ender 3 I can't even hear it working no no vibration that I noticed all around great board
Just installed one on my ender 3 had the same problem with the homing but fix it with latest update everything teaching tech said is true just buy one now best upgrade for your ender
I'm having the same issue but cant find the latest fix for it :-(
I'm technically challenged when it comes to editing marlin.. would someone have a firmware.bin for the v1.2 board? Or can someone confirm if the firmware.bin file that Michael has works without losing any new features?
BigMoike01 hi just just go to the github skr mini e3 page and download the firmware v1.2 put it on your sd card and power cycle the printer hope this helps
Ahh.. ok.. I actually just downloaded that an pit it on the sd card... the the auto home fix is in that bin file?
Humm, how do you know that the firmware has updated? I rebooted the E3 and the screen was blue, so I am assuming that it was loading... I have waited a bit now, but screen is still blue.. wondering if I now have to power down, remove sd card and power up??
BigMoike01 not sure? It’s about 10 seconds to load the firmware double check you got firmware for v1.2 board
DONT GET CAUGHT OUT LIKE ME
For anyone that has JUST revieced the v1.2 E3 MINI board and are trying to get your bltouch working on the default firmware but follow teaching tech's excellent video, Although Michael mentions about reversing the ground and +5v pins/ the UPDATED board is wired entierly different on the SERVO port i.e Gnd,+5V,PA1
Did you get the bltouch to work? After many hours of trying and reading commits for marlin 2.0 it seems like there is an bug in the code as they have changed the way auto bed levelling works. My machine doesn’t calculates the probe area correctly and goes off the build plate. If you have any tips I would be greatly appreciative. Cheers
Also this comment should be pinned as my pins were different like you said
Myles C ensure you’re using the dedicated firmware from big tree’s github page for the 1.2v only, all the bed settings are correct within the version of marlin so shouldn’t need to play around too much although by default it’s a 7x7 grid for bl touch , don’t be shy to read the config file for marlin there is soo many new cool features and most of settings have an explanation about the settings above them
George McCann yeah I did use their version first but I think it’s in a recent update that might be causing an issue. My bltouch works fine it’s just the bed levelling. I have gone through every line of the config and read all the documentation I could find. The issue seems to be with the probe locations which is based on the new probe offset syntax NOZZLE_TO_PROBE_OFFSET. Is your version using that?
Myles C I cannot even find that setting within config or config_adv
If you’d like I can copy my entire config settings and put them in a text file for you?
I had been looking at the SKR board this week, but was put off by the the major difference in layout from the Creality board. Finding out that the SKR Mini E3 is a drop in replacement I ordered it straight away. Thanks again Michael for another great video...and for your uncanny knack for knowing what I'm thinking about buying next for my Ender-3
Oh, and I went with the TMC2208 V2.1 stepper driver boards. Not the top of the line, but I figure an improvement of the stock drivers and acceptable at $30 (USD) for a pack of 5
I just bought too the E3 board. I will be using the stock board of the ender 3 for my mpcnc. I hope my E3 will came quickly, It said that they do not have tmc2209 drivers in their house, and they will get those about two weeks from now. Hope I will get it within a month or a 6weeks. Thanks for the video!
Hi, since im using RPi with klipper would i have any advantage in changing Ender 3 board to this one? Im asking becouse i found that when printing some parts e have problems i til this day i cant find if it is mechanical or software. By the way, great jacket ;)
Waited for this video, I would not buy this unless you approve it :) Great video! Will you show how to add filament runout sensor and RGB LEDs?
Have mine all up and running with BLtouch, filament runout and linear advance enabled. All running great thanks :)
Thanks for the Video, because i am in Love with this Board not only for the Ender 3, but also for my Ender 5.
Seems you recognized my comment on the mks gen l Video to inspire you on this Board. ;-)
WHYYY! are you first telling me this 2 weeks after i got my regular SKR 😊
hehe, same here :)
Same here as well!
SKR V1.3 is a superior board, don't worry. This one is just easier.
@@TeachingTech Cool, cause i'm following your teaching 100% here, without your video guides i would have been lost!!! Gonna try a "hybrid" setup with 3x TMC2208 and a regular DRV8825 for the extruder.
Will show you some love when i get all the holes cover being unemployed for 1½ left :) BTW you really need some merc we can buy. Doesn't have to be anything fancy, sticks, t-shirts and maybe something like a custom made mini toolset with your logo on, from china ;)
@@TeachingTech BTW just re-watched the video and figured i may have something interesting for you. I'm a toolmaker, 12 years experience. A new thing we've stated using in the industri these past couple of years are: *vacuum "tables"* for cutting thin plades. I made one 500x800mm table for an old CNC 2 years ago, got both the CAD and the CAM files (was made in Solidworks 2016 and CAM was mastercam). Let me know if you want them, was a "personal time" project so i rightfully own them :)
Regarding the routers power, i just got a couple of DC regulator from china, 30A max input 42v. With the mods i've seen (and copied) on the ender 3, you already know what i'm talking about ;)
I followed Micheal'advice and bought the new SKR min E3 v1.2. I'm reading from dozens of comments that many viewers are wondering just like me how to install BLtouch and filament runout sensor with this new board. Sadly Micheal is not answering any of those comments. Could someone please help us?
Skynetmod3d has a firmware for his sensors that works with this board, it's a version of Tim's firmware that's been modified to work with the SKR mini 1.2.
Michael just installed the SKR MINI E3 v.1.2 mainboard and I must agree that in terms of the noise level over the stock stepper motor drivers is night and day! When homing or printing, the stepper motors bearly make any noise at all! Now if I could just find a more quiet mainboard cooling fan and hot end cooling fan I would be in business! Definitely worth the money! Great video, keep the content coming!
As always another great informative video, thanks
You might want to see the "BigTreeTech SKR Mini E3 5V Regulator Failing - 12A 24V Load" video from TH3D Studio. Hope it's not an everyday use problem...
Hi Michael,
Amazing video! I was wondering if there are enough expansion pins for a bl touch and a filament runout sensor. I was planning to use the sensor you made a video about with a micro switch. Thanks!
Michael, can you point us toward which pins to put the runout sensor on. I guessing everything else will be the same as the stock BLT and runout setup. Thanks
@@tinkeringwithelectronics Not sure if this is useful or not but the TFT35 V3.0 display has connections for a runout sensor. It also has a connection for machine power shut-down once a print is finished.
Thank you for the information. I ordered the mini E3. :)
I just install a SKR Mini E3-DIp with 3xTMC2208 + 1xA4988 a month ago. Working great! On my original Creality v1.1.2 the stepper motor driver of the extruder died so I needed a new board anyway.
Ok, now I'm ready to install the skr mini e3 :D
How to plug cables for Z end stop - black and white when there is the Z axis plug [installing bltouch]?
The diagram is in the video and linked in the description.
When installing a BLTouch you remove and discard your Z end stop switch, it is no longer required as the BLTouch acts as your Z-axis end stop. You can remove the switch from the side of the printer and remove the old wire completely from the motherboard compartment.
I agree except I leave my microswitch in place for videos I make without ABL. Including the next one where the BLtouch is in the way..
Oh great....video comes out the day after I get in my MKS gen L to upgrade my Ender 3. I have it in and everything, all I need to do is upload the firmware.....Thank's Mike!
MKS Gen L is still a good mainboard!
If you have an Gen L, you might upgrade to an SKR 1.3 which has same formfactor. It has a CPU with EEPROM, so no need to emulate it on SD as on the STM32 boards.
As you already have the stepper drivers, going 32bit is less than 20$.
Also on SKR 1.3 you can use smoothieware.
@@oleurgast730 I Think I'm going to have to try the SKR 1.3 because for the life of me I cannot get the GEN L to work. I might have fried it. It accepts firmware but it does nothing and my MKS touchscreen does nothing. The temps show 0 across the board. The touchscreen is working but the buttons do nothing...
EDIT: Just wanted to say that I can control the printer when I connect through Pronterface via usb. No control with panel so at least I know the board is good and firmware loaded. Just need to figure out this darn touchscreen!
Thanks, Michael! Great video as always! I was hoping for a 32-bit board that would fit into the stock Ender 3 Pro. You are the best!
Hey I only made the video, not the board.
@@TeachingTech Yes but I didn't know it existed! :)
I just ordered it from BigTreeTech
Dude, i love that TT in the back. I got a bag of 100 RGB leds, lots of solder, wires, heatshrink, a 3D printer and plenty of filament. It's a HARD must to make my own like that from scratch with my own logo. Hell i even got a nano board and a spare chip so i can probably make a wave-program for the leds. Being a maker with printers is sick, thanks for the info and being inspiring. That goes to all these informative printer channels too!
Hey Michael, I bit the bullet and bought a CR-10 S5. Would a board like this be beneficial? Cheers, JAYTEE
I just finished putting one in my S5, it was a massive difference, quieter and no layer shift anymore.
@@originaltrilogy1 Thanks for the info 👍
Worth noting that the latest SKR mini E3 now has a new revision board (V1.2) which is not compatible with the V1.1 board firmware.
Check which version you have before flashing teachingtech's firmware.
info on the new revision here on bigtreetech's official aliexpress store:
" Dear customer,
On September 29 start sending version is BTT SKR mini E3 V1.2, only this firmware is currently supported:
github.com/bigtreetech/BIGTREETECH-SKR-mini-E3/tree/master/hardware/BTT%20SKR%20MINI%20E3%20V1.2"
www.aliexpress.com/item/33042554065.html?spm=a2g0s.9042311.0.0.4f494c4dfyWDdg
From the comparison of schematic V1.0 and V1.2 looks like previous version doesn't have UART communication with TMC2209 at all. In V1.2 they scarified RGB pins and enabled UART. Now, instead of RGB they use Neopixel (one wire interface)
glad I waited for this before upgrading
Great video I ordered it when you posted this, it has arrived now I've installed it, I didn't need to update it as Marlin on it was updated and Auto home was working out of the box.
What can I say it is so quiet it's unbelievable now I just need to update my fans.
Wonder if we'll see vendors fitting these as standard to their ender 3 clones. I'd pay an extra £30 for an ender 3 with one pre-installed.
There's ender 3 clones?
I've only had problems with this board, BLtouch has so many problems with this board.
Did you connect it as shown or with the 'probe' port?
@@TeachingTech Yes, it's connected to the Z-Stop Im on marlin 2.0-Bugfix. It's a V3.0 BLtouch and I've read so far alot of people have this problem with the board. And when they switch to the original Creality board the BLtouch works just fine. This is a video of the problem we are all having (i.imgur.com/BEdxRFO.mp4) So while probing it randomly fails, you see the BLtouch led becoming red but the trigger is not registerd by the board.

That looks like a firmware problem, but could be a marginal signal. Is it only the BLTouch version 3 affected? If so, perhaps the hardware fix for the original Melzi boards would work?
@@TeachingTech Reddit has lots of problem comments about the mini and the DIP boards including dead drivers and BL touch sending nozzle into bed or model.
@@YpsilonTM Interesting, I have been running this board and a BL-Touch version 3 and haven't had that problem.
Works great on the original CR-10, too! Just use a nylon screw in the mounting hole near the center of the original mini E3 board as there is a resistor very near the hole. Nice drop in replacement!
Top Man Micheal! Ive been holding out upgrading as i felt something better would come along, Just ordered mine for a mere £19.28 with all ali express codes, im sure ill forget about it until it comes...... till then, i never miss your videos! keep at it. Always watching :)
ANd BTT are saying there is a shortage of 2209 chips, and they wont have them in until mid september...
Mid October now... Ordered the normal one with 2208 just hours ago 😁
They seem to have the dip version available for immediate shipping.
@@Waltkat most of the problems people have been having on reddit have been with the dip board. I would avoid that one personally. I went ahead and ordered the non-dip version and figure I'll just wait, and when it arrives it'll be like a surprise present.
Just be mindful of the center mounting hole on the E3 boards. It’s dangerously close to a resistor that can be crushed by a screw head, so it’s best to leave that screw out.
Great tip, thanks Keith. Thanks for all your work with Marlin too!
I was looking at the SKR 1.3 and a set of 2209, but for this price/convenience, I think I'll do this. Thanks so much!
You might prefer the SKR 1.3 as it has an other CPU. The SKR 1.3 can be used with smoothieware, which is more advanced than marlin 2.0.x. Marlin 2.0.x is alpha. Until 07-30-19 even the HAL for the STM32 was defect, as soon as you went aside from stock configuration, strange things happened (like activating the probe input to use a simple film probe or a piezo, all endstops where deactivated).
The CPU on the SKR1.3 is much better supported, as its the same as on smoothieboard - the STM32F1-series is relative new for 3d-controllboards.
Also the STM32F1... have no EEPROM. Marlin emulates EEPROM on Micro-SD. Can give some trouble if changing the SD-Card...
(because of one of your vids) i got the regular SKR 1.3 and added TMC2130/DRV8825 to a cheap TronXY XY-2. its an amazing printer
Sorry to ask but would you be able to make a config file for the SD card for a ender 5?
Have you find an answer? Been busting around and can't find a clear how-to (at least for my understanding) on how to install it. When I followed his guide for the SKR 1.3 and changed the settings I found for the Ender 5 (board, port, etc) I keep getting an compile error ... very frustrating for a below average user :-)
@@GertGybels yes, I found a Reddit post where someone made up the configs and you just drop it into Vs code will link
Search google for reddit skr mini E3 ender 5, should be first result post from sky8000.
Just a warning tho mine worked I got one good print out and then the firmware broke down, and it no longer talks to the hardware. But this post is updated
Feel free to pm me on Reddit I use the 8-bit_infidel
@@8bitInfidel Thx alot, so it happens I ran into the reddit post a while ago and downloaded his repository from github but was for the v1.0 and not the v1.2. I did took some of his settings but compiling still hot messed up. Maybe tomorrow at the office I'll dive into it. Thx for your help!
@@GertGybels I am having the same issues keeps giving out errors now, I'm in the middle of recompiling I will reply if I have any luck and will uplaod for all
Actually, the Cheetah is less expensive than any version of the SKR, and also carries on board trinamic drivers, yummy isn't it ? 😉
I looked into it but there seemed to be some persistent bugs. I'm sure they will get them sorted though.
@@TeachingTech well, I guess it's fixed for now as it works as a charm here on 3 printers 😉
Just got my Ender 3 Pro and a few accessories (upgrades), including this board. Your installation diagrams are great! Having built numerous computers, this board would have been only a few minutes to change, EXCEPT for the insane procedure that Creality appears to use in which they HOT GLUE all of the connectors in place. It took me almost 40 minutes to get all of the hot glue off to the point where I was confident I could pull the connectors without yanking the sockets off of the PCB. It's a good thing I wasn't saving the original board, because despite my best efforts, some small amount of hot glue remained on the hot end thermistor socket which was enough to cause the socket to pull partially out of the PCB as I was removing the connector. Who does this? Anyway, GREAT content and I'm learning TONS from you!
Really nice to see a drop in board for the Ender 3. It would be extremely nice to see a video of this board with one of the touch screens. That's the main reason I want to upgrade.
I tried a few touch screens and thought they were a waste of money, you can change everything from stock lcd with marlin 2 on 32bit board, the touch screens run their own arm cpu and interface and talk to the printer over a serial connection. The lcd is much faster
RIP Ayrton Senna, I am still sad 25 years later
Looks like they are sold out :(
I think the 2209s are the hold up. Expecting to be shipping in a fortnight or so according to what I've read.
I loved your blouse, Grettings from Brazil
Patience is a virtue! I had been 'humming and harring' about a mainboard upgrade since owning my E3. Almost bought GEN L and then the SKR 1.3 a few times but wasn't quite happy with the set up and alterations needed. Thank you so much as this seems to be the way to go. A straight swap and possible minor issues that are easily resolved to provide a decent upgrade. Excellent!
Now do the skr pro!
Trying to decide what printer, got one ready. Maybe the CR10 Max but I need alarge LCD to go with it.
Sold out till October due to 2209 shortage :-(

I ordered one on 7th July, shipped 15th, and it arrived 29th August. That’s pretty slow for most things, and I suspect they are having problems meeting demand.
Hi,
Thanks for a great summary video of that board. It will help a lot people to get started with what I also consider the best board for the Ender 3.
Your video however show the mini ups as an extension available for this board but this mini ups deliver 12v and the ender 3 is 24v.
I have them sitting here but haven't looked into them yet. I'll probably make a video on them at some stage.
@@TeachingTech I do have one. It works fine for 12v but I cannot see how it can work with a 24v system. When charging them with 24v it might not blow (each caps is protected and unless you go over the fuse, the ups should be fine. Unless one of the component is rated for 24v max). There are voltage regulator around the circuit that will force the voltage to be max 2.5v x 5 = 12.5v. If I have not made oversight, this will force the voltage of the PSU to output 12v or will take a lot of heat in a single resistance. I would not test it on a 24v system.
Best case the thing works but suddenly your motor gets half the voltage so needs twice the power and start heating. It's 0 risk for the printer but the charge wont be enough to park the head and save everything before proper shutdown.
Anyway this sounds like an interesting experiment to drive if you wish to know what happens used on a 24v system. Just be prepared for the ups to smoke. If I am wrong with the voltage regulator behavior, then the supercaps will explore and the gas of caps are pretty nasty.
Anyway I'll be really interested to see an actual test if you are willing to take the chance ;)
I bought this board because of this video about 4 years ago - TODAY I installed it.
One problem - now my printer is SOOO quiet, I have to go and check if it is still printing even when I'm in the same room :)
Great video as usual Michael 👍👍👍👍 just went ahead and ordered one. I hope it will fix my layer shifts at speeds >60
Spartak Fedorovich
You may end up having to upgrade the y-axis motor. At least this board has the grunt to drive a bigger one if necessary.
@@boggisthecat why would I need a new Y stepper?
@@sp78rus If your stepper isn't strong enough to handle fast movement of the Y axis, it skips steps and causes the layer shift. You can with this board increase the power going to your existing stepper motor, that fixed the problem with me.
Thank you very much for your work man. Note that a new bug was fixed 4 days ago that causes the overheating of the steppers motor. Just in case you wanna update your compiled firmware
i just tried using his stock firmware and my x is burning up and shutting off. thanks for your comment so now i do have to go build my own anyways lol. tried to save some time.....
I just installed the SKR Mini E3. It was very easy. I didn't have to flash a new firmware, everything worked well. I think it solved all the surface artifacts and apparently my Ender 3 prints as well as the Ender 2 now. I still have to check with a grey or black filament to be sure.
Love de Airton Senna Sweater. One of my idols
Michael, Thank you so much for all you have and continue to contribute to our community. My question is that given all the mods you have done on your Ender 3 now with this edition are you satisfied with the quality and ease of use of your printer? As well because I am on the fence to purchase my first Ender3 due to all these mods that are above my technical capacity to implement, I was wondering if you offered your services to provide fully mod printers to your specs? Basically, I want an updated and tricked out Ender out the box without having to modify it myself too much.
Thanks Michael. Your code helped me immensely. When you do your follow up video that you mentioned, can you have a go at Unified Bed Leveling with this board. After following Chris's Basement instructions, it will not compile and I do not understand the errors even after googling. Thanks for your help and I look forward to your followup video, Christian
Thanks for this video I bought the card not long after seeing this but have only just changed the card! Testament to how good the original Ender 3 design works. Nice to have silent steppers now though 🤣
Awesome video. Just ordered that board.
