High Temperature All Metal Bi-metal Hot End Upgrade Ender 3
ฝัง
- เผยแพร่เมื่อ 18 เม.ย. 2024
- Chuck shows you how to add a Bi-Metal High-Temperature Heat Break on Ender 3 V2. This upgrade can allow you Ender 3 to Print up to 260 C and higher. This can also be done on any Creality 3D printer or Creality clone. This Heat Break can extend the life of your PTFE tubing, allow much higher temperature printing, and may even give you better printing results over time. So for the added cost, you might consider upgrading your Creality HotEnd to a Bi-Metal Heat Break.
Click on link below and then go to All Products then CopperHead Heat Break and
select the "C-E version" for Creality Hot Ends to find the heatbreak.

I have this one on my printer for about 200 hours, and its great so far. Nice to see you recommending it.
You are a life saver chep. On this summer i started printing since then you have been great tutor. Thank you so much Mr.Chep
Great to see this reviewed. I liked it a lot after installation, it really improved experience with PETG, Colorfabb NGEN etc, but I struggled to get the ideal retraction. In the end e3d were doing a sale on Titan extruders, so I turned my ender max into direct drive, and changed retraction to 1mm and tuned the esteps manually. This seems to have improved things a lot - literally zero stringing, no artefacts on Benchys etc. And PETG still printing great.
Another mod for my Ender 3s thanks to CHEP. I added this on my Ender 3 with the BGM style direct drive and so far so good. I’ll be ordering a second one for other Ender 3, and probably convert that one to direct drive as well (I had the parts for nearly a year but have been too busy printing to stop and upgrade it). Thanks for all your great videos and profiles!
I've bought an Ender a year ago. Just few months ago I learned differences between shape, walls, density etc... You're my new Guru!
Hi Chuck. You missed an important step: Reset your Z-offset (Nozzle offset from probe). Since nozzles will not always end up in the exact same position, it is a very important to prevent damage and have an accurate offset. Great video! Much more help than the Slice Engineering Q-code
Also run pid
I’ve heard you should season this. What say ye?
What about e steps?
Thank you for this! I just installed one last night and this video helped sell me on it. Your instructions helped because I couldn't find any on Slice's website, LOL I just found your video on the ABS corners. I'm about to try printing that for the first time.
Hey Chep. New to 3d printing and new to the channel which is fantastic I must add. Your descriptions and walkthroughs are perfect.
I've just purchased one of these for my newly acquired CR10s pro v2, and, just now have purchased a micro Swiss nozzle to accompany it.
I hope it'll be a good combo which will minimise clogs amd the such. Keep up the good work 👏
I think you’ll like the heat break. As far as the nozzle, I’m not sold on it. And I suspect you’ll have to run it hotter than brass.
Thank you very much for more tips they are genuinely appreciated a fan from the UK
Oh... Pretty impressive indeed, Chuck! 😃
Thanks a lot!
Stay safe there with your family! 🖖😊
I knew this could be possible
Thanks for confirming this...sir CHEP
I just installed this upgrade last night. With the stock heat break I was able to peak at 9.62 mm³/s flow rate and now I'm reliably at 16.84 mm³/s. The main mod I did was mounting the stock Ender 3 extruder with the SpeedDrive direct drive mount on thingiverse.
Thanks Chuck, just ordered one today from Slice Engineering
What a great application, and simple upgrade 👍.
Thanks for sharing your experience with all of us 👍😀
Thank you for this addition, for my adventure into using PETG. And, who knows, I might get brave and try ABS. I have functional parts tgat I made in PLA, and they did not 'weather well'; so I am hoping a material change will improve those.
Hi Chuck, thanks for making this video, after watching this I concluded the heat break was a better option for me than going with an all-metal hot end. I did run into a few issues with the installation on my Ender 3 Pro, related to the heat break being longer than the stock one and pushing the nozzle lower; sharing in case others are in the same position:
- The M3x16 bolts that go through the bottom of the hot block and into the heat sink are now too short - I asked Slice about this and they recommend just using the grub screw to attach the hot block to the rest of the assembly
- I had to shim my CR Touch with a few washers between it and the bracket, because the nozzle was now below the probe
- The part fan is now blocked by the hot block, so I quickly remixed a longer shroud to account for it; it's part - 369993 on Printables
What kind of washers did you use and how many? I am running into that issue now.
Love your videos and that is going to be next on my Ender 3 v2.
You’ll like it. Use the link for discount.
Shipping to Aus was far too expensive, 👎but Slice helped me find a local retailer. Good service 👍
Hello Everyone Great Video CHEP I just did this upgrade on my Ender 3 Pro run my first print with the upgrade and it looking great NOTE BLTOUCH USERS RESET AND ADJUSTS YOUR Z-OFFSET that is all thanks again for the great video I will be doing with to my NON PRO Ender 3 tomorrow.
If you screw it on just right you can use it with bl touch. I screwed the heatbreak so it was flush with the heatblock but I would recommend going 1/2 or 1/4 turns back from it to make more room. I was left with .5mm z offset. As long as you put the bed clips in strategic spots (if you have the low profile ones to go with the creality glass bed). If you don't check the bed clips you can have the print hit them causing G112 error.
Just the video i needed!
I just did this mod to me Ender 3 V2 and let me tell you it was not easy to unscrew the stock heat break from the hot end. I had the hot end set up like you in vice grips, but even when heated to 240C I couldn't budge it with needle nose pliers. The stock heat break seems like hardened steel. Finally was able to remove it with a small pipe wrench lol.
ahh good so its not just me. who cant undo it
I'm running a titanium version of the heat break on mine. I took a chance on it and it works great. One of the draw backs is I have to do a cold pull after every print otherwise it will jam the next print if it cools down
That means ur heat break ain't working very well lol
This is why you want to avoid buying cheap heat breaks. It's one of the most critical parts of the machine, and it has to be machined really well and be designed properly. Either that or hotend cooling situation is not very good. Having to do a cold pull every print isn't a sign of a properly working hotend.
Couldn't you just modify your gcode so at the end of each print it retracts a lot, and at the start of a print it advances an equal amount?
Works great. Just don't forget to adjust your retraction!!!! I was banging my head trying to figure out why I was getting stringing, clogs, and binding,. Duhhhhhh the filament is not as deep inside hot end anymore.
I had to drop my retraction down to 3 from 5.5 to get it to start acting right to be able to do a heat tower then retraction tower.
You are a hero! :) Always watch your videos!
Chuck, love all your Friday episodes.
After watching this one, I went ahead with a hot end upgrade. Now a couple of frustrating weeks later, I think I am about the same print quality I had with a PTFE tube to the nozzle. I've watched other all metal hot end upgrade videos. It'd be nice if anyone mentioned potential issues with all metal hot end.
Like stringing, blobs, and clogs. Cause it's been a pain.
My 2 cents. You can leave them on the Take a penny, Leave a penny jar.
I’ve had none of those issues. Mine printed better right from the start. Same profile.
I have the same problem! Do you have a solution 🤔
My ptfe tube was shot too so change it to capricorn tubing and install my bltouch to 🙂
I made the mistake of buying the mellow bi-metal heatbreak, their design is not great because they don't have it setup so you can easily slot your filament down into the tip of it, so it winds up jamming up whenever I try to swap out my filament on my Ender 3. The only solution that even remotely has worked for me was to take the ptfe tube out of the coupler going down into the hot end, feeding the filament through and then hitting it with a lighter to soften up the tip so I could stretch it to a fine point, which I am then able to fit down into the tube inside the heatbreak. I'm tired of following this process so I just ordered the copperhead c-e bimetal heat break based on your recommendation Chuck. Thanks for posting great informative videos to help folks out.
Let me start by saying I have been running straight Capricorn tubing and have never had a failed print due to a clogged nozzle. I thought I needed this so I bought the Slice heat break and installed it yesterday. Used my standard slicer settings in Cura and the print failed due to a clogged nozzle in about an hour. Today I changed the retraction distance and minimum extrusion distance window to 3mm. Default is 5mm. The print made it several hours but failed again due to a clogged nozzle. The Slice heat break was removed and I am back to printing with the original set up. Wished I would have read more of the reviews before I bought this. Can't wait for my Prusa MK3S+ to get here.
Did you verify the nozzle and heat break had no gap between them?
That’s usually the issue.
@@FilamentFriday Yes. I heated the hot end up, cleaned out the threads by threading the nozzle and head break in and out. I made sure that the nozzle and the end of heat break had solid contact. Thanks for all of your content CHEP.
@@FilamentFriday Bi metal do not work ok with PLA and bowden setups.
Hello Everyone Great Video CHEP I did this upgrade on my Ender 3 Pro running prints with the upgrade and they looking great NOTE BLTOUCH USERS RESET AND ADJUSTS YOUR Z-OFFSET I personally also readjusted my E-Step also again great video CHEP
@@LouisePaisleyUK Wow. lol Well first off I said I personally readjusted my E-Step I didn't say that it was 100% needed. I am glad that you seem to be able to use the defaults on your creality printers but with the changes I have personally made to include the one in the video I personally decided to run some calibration test after making this upgrade and came the personally decision that I needed to adjust my E-Step because I personally saw a change in how much easier and smoother the extruder was able to push the filament through after this upgrade. I would be very interested in CHEP thoughts on this.
Makes me want to pull the trigger on the Aguila. I currently have an Anet AM8 with a genuine E3DV6.
Aquila with the new Alex jyers firmware is amazing.
I ordered one yesterday before watching this video.
I noticed some strange stringing I never had in my past prints.
I removed the fan cover and a big petg blob was all over the hotend!
After removing the goo and disassembling the complete hotend, I found that the original heatbreak was cracked.
Ordered a new hotend and a bi-metal heatbreak. Didn't want to go for an all metal hotend from micro swiss. The original fullfills all my needs and I think it will not give me more benefits.
I order one 2 days ago for my Ender Max as soon it get here i'll change the tubing for capricorn and i'm going to install belt tension upgrade after i'm thinking about the dual z upgrade, have you find something for using a touch screen on the max ? 😉 great videos and thank you
Hello CHEP what tool did you use to measure the tubing? And if you have a link that would be great! I want to make sure I have all the right tools to work on my 3D Printer so any others you want to throw at me would also be great. Thank you for the videos and the help!!!
I'm definitely going to upgrade my hotend with this, it's a lowcost alternative to an all metal hot end such as the microswiss, but keeping it almost stock.
Thank you.
You're tempting me to try ABS again... Bad man!
This was possibly the single best upgrade I made to my Ender 3s. I absolutely hate the design having the ptfe tube butt up to the nozzle, it caused so many issues. As soon as I swapped to these those issues have completely disappeared.
That was probably a different problem. Since most people are printing with Bowden tubes perfectly fine. I've had zero issues with my Bowden tube. Even before I upgraded it to a Capricorn tube.
Only reason I'm getting the all metal hot end is to print at higher temps.
Do you find that it helps prevent the gap clogs? Or does it still need to be super flush?
What issues did ir solve?
@@dangerous8333 I wouldn't say that's the only reason. Changing nozzles is easier too since you don't have to go through extra steps to ensure the PTFE tube is butted up against the nozzle.
what retraction settings do you use now?
I am looking into hotends for my Ender 3 V2. The Red Lizard Dual Gear Extruder, Red Lizard K1, Sprite Extruder Pro Kit 300℃ High Temperature, Spider High-temperature Hotend, Pico Hybrid Hotend, and the Dragonfly. I want to print Nylon CF, and TPUs in the future. Hope you cover these in the future!
Can you do a video on putting a ender 3 v2 in a encloser? I’m worried about the power supply getting to hot. I have no idea how to relocate it outside of the encloser
Great video...
Would you recommend after doing this, wouldn't a PID autotune be a good idea?
100% definitely. Any changes at all to the hot end, even a fan replacement, it's worth doing. If you've never changed your machine, it's worth doing!
Would there be an advantage or disadvantage if you installed this upgrade and did the hot end fix from another one of your videos?
thank you so much for this, I've been looking for any information on the slice engineering system on the Ender 3 v2 but haven't had any luck finding good information on it.
Thanks.
Great video! I already ordered mine for an upgrade. I have a question. I plan on buying a new stock hot end for this. Should I heat up the heater block to install it or can I do it cold? Thanks!
Heating it up makes it easier.
Chep thank you!! I have a question, will it work with nylon and or the carbon fiber nylon, and is the part as good as the all metal micro Swiss hot end ? Thank you again for all your videos and your time and knowledge!! Hope today finds you smiling!!
If you modify the firmware to go above 260°C
Great review, I do have a question, did you have to reduce your retraction distance when using the bi-metal hotend.
No, didn’t change it at all.
Great video, I just bought this for my Ender 3 Max. Question I have, do you need to do a PID autotune after installing this? How is that done on an Ender? Thanks much.
You shouldn’t need to. I didn’t.
Filament Friday!
i've had some frustration with this heatbreak clogging on my ender3. it works awesome if you make no mistakes and operate your printer flawlessly. but certain common mistakes seem to easily clog it - filament runout, or leaving the heat on for awhile after swapping filament, or leaving the heat on if you left it for a second to warm up while you do another task, or even if you leave the heat on for a bit to re-level. even with good thermal pasting and the heatbreak fan running the whole time. these are all things that happen to me at least once in awhile, and recovery is fairly laborious... a complete hotend disassembly, and possibly a ruined heatbreak. i tried clearing the clog by heating to 260 for awhile and trying to push the clog out with a 1.5mm allen key, or an accupuncture needle from the nozzle side, and it just wouldn't budge. as a last ditch i disassembled, removed the heat break, and torched it and then finally was able to remove the pla clog. heh the bimetal kinda works TOO good. i may have ruined it by torching... but so far it seems to be printing ok again. i've read about others having clogging issues with this heatbreak also. i wonder if this is what inspired your recent heat creep video. i know you have had a lot of issues with the design with ptfe down to the nozzle, but frankly so far this bimetal thing has caused more show-stopping issues for me than ptfe-to-nozzle ever did, and i'll probably go back to that (or upgrade to a v6 hotend). it might be that the printer i use this in is kinda full time pla, i don't really do petg or abs on it... perhaps those are not as finicky with this heatbreak, which is kinda counter-intuitive.
Same, more issues after installation then before with stock setup
@@losangelesrccrawlers3738 it hasn’t happened in awhile. maybe i’ve not made any mistakes in months (seems unlikely). i think i heard heatbreaks can be take some run-in to season like some people say with their build plate (i’ve never really studied but i’ve heard some build surfaces work better after some use)
Hi Chuck, I really enjoyed your videos, i purchased the HB from Slice however I noticed that the nozzle goes in 21/2 turns. Should i relevel and change Z offset?
Printed PETG at 230°C for a few hours daily for a week and noticed the extruder starting to skip steps, the infamous clicking issue on Ender 3 style printers. I pulled out the PTFE liner and it was burned severly and obviously was on the best way to clog up completely. Now I ordered the Bi-Metal heatbrake from Slice Engineering to cheaply convert to an all metal hotend and I will see if this eliminates this problem.
It will
I'm considering between this and the V6 hotend. However, this one doesn't provide an extra thermistor or heating cartridge, so could I ask if the stock one can withstand up to around 285-300 degree celsius for high temperature printing (safely)? Thanks :)
Another great video! Ordering one for my CR-10 but not seeing any discount. Will still get it though.
there is a 5 % off button which appears on the slice website. You also have to click that one
I got extremely worried for a minute after i installed the heat break. I also noticed it is to tall for the cr touch. I did the auto level and adjust my z off set. Then i had to go to work. Guess just have to keep on it when i print just in case if i have to change the z offset. That would have been a nice tidbit of info to have. Very glad after came back to read the comments to see if i was the only one having that issue. Do they make some kind of back plate or something to make it higher up?
Is this a replacement for an all metal hotend to do nylon?
I am thinking about upgrading the stock hot end on my Ender 3 v2 to be able to print with higher temperatures (for ASA). But I have heard that the heating cartridge and thermistor wires are also insulated with PTFE. Should I worry that gassing will occur on those parts or should it be safe?
I see no mention of retraction distance or speed with adding this new heat break. Can you please update with info on if the standard retraction 6.5mm is too much or not. Or if it need to be reduced.
@CHEP, why do you install the nozzle first??? This is not how the manufacturer's (Slice Engineering) instruction describe and this is also error prone. The proper way is to screw in the heatbreak first, until the top of the lower thread of the heatbreak are flush with the top of the heatblock. This ensures that the heatbreak is screwed-in deep enough that the MK8 nozzle *will* bump into it prior the MK8 nozzle shoulder bumps to the bottom of the heatblock...
I installed this heat break on my Ender 3. In order to print high temp materials like PC or Nylon, do you think it's necessary to upgrade my heater block, thermistor, or heater cartridge? So far I've been printing ASA successfully but I'm curious about printing PC.
Two weeks with a filament oiler installed and you will never have a problem again,I almost bought the internet BS till I tried it and was blown away. I went from constant jams,and failed prints to never having a malfunction since. Just try it and thank me later
Already showed that: th-cam.com/video/OG7We83M5gc/w-d-xo.html
I put one on yesterday and it does seem to help a whole lot.
One thing I noticed was blobs of what kind of looks like burned oil and plastic on the print. It didn't seem to really hurt the quality at all, it just looks unclean. Possibly I put a little too much oil on the sponge, or maybe I need to run it hotter until the tube is fully cured? If you have a tip on that I would be grateful.
I'm already much more happy with it than I was 2 days ago when I almost switched back to the stock tube, before I saw your tip.
Hey chep great video brother! What extruder do you have on this ender 3 v2?
Still have the stock plastic extruder but an EZR is coming soon.
@@FilamentFriday okay that's for the reply!
Does the Ender CR10S use the same hot end? Could this improve the performance of the printer?
it's a shame not to take advantage of this modification to try to raise the temperature and print nylon at 300 ° by modifying the ender. Is it possible ? could you make a video on it? it would be great to print nylon carbon on an ender
Hi Chuck, I purchased the Bi-metal heat break for my Ender 3 v2 Neo. After I started putting together everything (based off your video) I found that the heat break does not fit into my heatsink. Do you have a recommendation on a new heatsink that will work with my Ender 3 V2 Neo?
Awesome! Gonna Doit! No need for an expensive Swiss. Haha
Chuck, After installing this heat break, did you have to adjust your retraction settings? Some have recommended reducing to 1mm to avoid clogging. I currently use 6-6½mm on my E3Pro with the stock hot end depending on filament.
No, it’s still a bowden so it needs higher value. I use 5-6 depending on the filament brand.
If the slice engineering is too expensive a all metal throat can be had from the usual Chinese supplier for maybe 8 bucks a piece.
I deal with clogging by burning cooking oil inside the filament path before installing it.
How did you increase the max temp? I assume it is capable of higher temps now?
I bought the Slice Engineering heat break after seeing this video. I tried it right away and my print quality dropped considerably. I went back to stock Creality setup and the print quality was back up to the quality I expected.
Yesterday, I had to replace me fan motor so I decided to try it again while I had it apart. I put the Slice heat break in with a brand new Microswiss M2 nozzle that I bought at MRRF this year and reassembled it and again it prints like crap. I had re-leveled the bed. Tried slicing a quick print in the latest Cura and Simplify 3D and 2 different rolls of PLA filament. For some reason, whenever I stray away from the stock Creality setup, print quality goes down the toilet.
Any input would be greatly appreciated! Thanks!
would the retraction distance change with this installed?
Chuck, thank you for all your videos. I installed this upgrade. The printer printed fine once. I tried the 2nd print and it was plugged . The extruded was tapping. I could not clear the plug until I pulled the hot end apart an used a small drill to clear the plastic in the heat breaker. After I got it clear I tried again and the printer plugged again after on successful print. I am printing pre foamed Lw pla to print airplanes. This material is a little coarse. Just wondering if you have any idea how I can fix this. You’re a busy man so I understand if you don’t get time to respond. You have really helped my 3d printing with your videos
I’d contact them to see if there is an issue. It shouldn’t do that.
This sounds like a pretty decent cheaper alternative to an all metal hot end if I'm not mistaken
Actually creates an all bi-metal hotend with improved anti heat creep.
Did your retraction settings change?
It cost me 57$ cad for montreal Canada I cant wait to install it on my creality ender max that is clog after a 3 weeks of printing 😁
Hi Chuck, while watching your video to install my new heat sink, i noticed you don't have the rubber shroud around the heat block. Is it necessary to have that on, I trimmed the pointy part off to make easer to change the nozzle.
It helps clean it when filament ends up there and also helps a little with temp stability but it’s so minor. But for videos I just take it off.
Good video. I have been searching for a video on what upgrades are required for a Creality printer (e.g. CR-10S) to print Polycarbonate filaments at around 300 C. Any advice is appreciated.
This should do it (plus firmware update) I haven’t tried it though.
@@FilamentFriday Awesome! Thank you CHEP.
@@FilamentFriday CHEP do you think this will be good enough not to go for a all metal hotend like the one from micro swiss for my CR10s?
Yes
How to change the printers max-out temperature after installing this heartbreak? In the firmware?
Hi Chep, my Heatbreak is stucked on the heatasink, its the original creality heatsink of my ender 3 v2. It didn't slide smooth like yours. Do you think i have to heat the hot end so the heat break can get out of the heat sink?
Can you show us, the same change on the Ender 3 S1?
Chuck, i have heard from others about adjusting retraction for pla when withing a heat break similar to this. Any feed back on that?
Shouldn’t be any different.
Are you recommending the Slicer engineering Heat Break over just getting a new All Metal Swiss Hotend?
Yes.
Hello, Mr. Chep. After watching this video, I bought the Slice Engineering Copperhead Heat-break model C-E for the Ender 3, I got the same problem as Bek. After about 2 prints, it jammed on me. I had not changed any settings yet from when I was using the Luke Hatfield modified fix, that had been working great for about 20 prints, and only stopped when I switched to the Copperhead heat-break. My guess is that the settings in Cura need some tweaking, and not skilled enough yet in Cura to know what they are. (There are a lot of them.) What settings do you use for the Copperhead and why? I am currently testing settings out myself, and would like to trade results.
I use my profiles linked in every video
The only two settings that have had an effect on clogs for me with the Copperhead C-E are changing the retraction distance from 5mm to 2-3mm, and retractions speed from 45mm/s to 25-35mm/s. I am still getting clogs and jams, but at least not nearly as often with these settings. So, at least I can do small prints, and clear the jams on the fails. I have recently dropped the settings from 3mm, 35mm/s to the new settings of 2mm, 25mm/s, and have not had a jam since the 2mm, 25mm/s changes, about 1 day so far.
Bummer I have the same issues
I'm looking at the slice website but they don't have just the heat break. They seem to sell the heat break and a hot end in a kit. Am I missing something? Seems a little misleading to send you just the heat break and not sell it that way. In canada BTW
i'd love to get one but it seems hard to find for my ender5 where i live.
Hey Chuck trying my second one as the first was a flop and everyone said I may have got a bad one so will post to morrow or Sunday with an update on this one I hope it works and I did just get a bad first unit
You have great videos and I look forward to them and wanted to thank you for the help with my printer over the past 2 years if not for you I'd still be lost
THANKS!!!!11
Any updates?
Bought my heatbreak officially from slice engineering, about two years ago. Funfact: I am still modding this project Ender3 V2. So I cant Tell anything about the quality. But what I can tell is: my Hotend got longer about 1,5 mm. So the standard fanducts wont fit. And it’s really difficult to get a fitting duct or adjusting the lengh precisely. What about the lengh of your heatbreak? Did they fix this issue in the meantime?
Did your E3V2 not come with a silicone sock on the heater block, or did you intentionally remove it?
I removed it.
Just bought this heat break and installed it last night. Although I print primarily PLA, I thought this would be handy if I chose to print with other materials. However, after installed this my print quality went way South. I've re-leveled the bed, tried different temps and retraction settings. Pretty disappointing for printing PLA.
I'll be switching back to my original setup.
I think i have the same problem. The quality is not so good. I have stringing issues and i can't adjust the retraction distance because at more than 3.5mm the hot end gets clogged. So i'll try to use the oil dispenser trick. If it doesn't work, i'll be switching back to the original setup too.
I'm talking about PLA, didn't try other materials yet.
@@facundogomez4892 Did you ever get it working right? I'm having similar issues with under extrusion (possibly because of clogging) when doing a lot of retraction after the upgrade.
getting a lot of stringing also been trying all speeds and retractions. nothing works yet. spent a lot of time.
@@AndyDillbeck Yes, i managed to make it work reducing the retration distance at 1.6, retraction speed at 40 and increasing noozle's temperature at 215°C. I reinstalled the bi-metal and the noozle tighter, so i't doesn't loose material, and i installed a new aluminum extrusor, wich took me some time to adjust it right. The problem is that there is stringing (looks like you have to accept it for pla and bi-metal), but there is no clogging and It worked continuously since then.
I don't even want to imagine printing at 260 degrees with the PTFE touching the nozzle o.O
The fumes..
Grub Screw ? Never heard it called that before !
Google “grub screw” and see what you find.
@@FilamentFriday Thank you - found a wiki link - learning something new here - "A set screw is often headless and threaded along its entire length, so that it will sit entirely inside that hole; in which case it may be called a grub screw or blind screw."
I’m about to do this, do you have to adjust the Z limit switch to adjust for the longer heatbreak?
Just the bed level.
Just what I need for my Ender-5 Pro. Which one would be the correct one for a Ender 5 Pro ?
The same one he used. All Creality Ender machines use the same hotend.
I'm trying to upgrade my anycubic neo hot end full metal one is there any advice what copper heatbreak I can use
I bought one of these from your link to Slice, and it seemed to work really well for printing ABS, but I'm having a heck of a time getting the PLA to print, with lots of under extrusion and the extruder gears doing some kind of backlash. I suspect it might have to do with retraction, but I'm just having issues with it.
Any videos or suggestions as to how to get it dialed in correctly? I'm hoping I don't have to switch back to the old one.
Before the switch on the stock ender 3 I was had the hot end at 200c, 5mm retraction, basically all the stock settings.
Now I've upped the temperature to 210, which does seem to have helped, but not solved all the issues.
I’ve not had any issues like that with PLA so not sure what to suggest. Maybe your cooling fan is failing and your getting heat creep in heat sink.
Same problem here, simple objects like cubes are easy, but with more complex figures that requires a lot of retraction you will get clogs or stringing
I use same 6 mm retraction as before without issues in all my prints. It’s been a great improvement on my V2
Ugh. This reminded me I need to swap out the ptfe tube on my kossel. Probably why it's starting to look like it's under extruding
I just got a cheap one off ebay which looks like brass with a stainless threaded part down the bottom. It has only about 5mm space for the PTFE tube to go into it, which is much much less than the Slice Engineering model you've got here. I wonder if that's a good thing....
I talked about those in the video. I don’t recommend them.
cant find it on their website. theirs has the heat block with it for 99 dollars. not seeing just the tube. direct link for ender 3 v2?
Have you noticed any problems with this when trying to re-advance PLA to the nozzle after a retraction of a few cm? I had some issues with that (causing under-extrusion) when trying out a prototype metal/ceramic hybrid heatbreak which was designed to do the same thing (although it worked just fine otherwise). This is because the PLA is a bit malleable when it leaves the hot area and can distort so, when you re-advance it, it gets stuck on the rigid metal lumen (whereas the PTFE has some 'give' in it). Probably won't be an issue with ABS.
So far, no.
this will come down to machining tolerances of that bore in the heat break and what ptfe tubing your using. if there is a substantial difference in diameter you might have an issue. slice is pretty good with that though I doubt you will have an issue with them. well polished and machined tight.
A lesser copycat might give you some grief.
