High Temperature All Metal Bi-metal Hot End Upgrade Ender 3

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

[@jjclarkson3261]

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

[@Bellacera2010]

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!

[@lff12]

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.

[@vanloggins]

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.

[@funddesexgluma]

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

[@LargeKid]

What kind of washers did you use and how many? I am running into that issue now.

[@rpg01x]

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.

[@FilamentFriday]

Did you verify the nozzle and heat break had no gap between them? That’s usually the issue.

[@rpg01x]

@@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.

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!

[@DwellerDesert]

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.

[@FilamentFriday]

I’ve had none of those issues. Mine printed better right from the start. Same profile.

[@frits183]

I have the same problem! Do you have a solution 🤔

[@Sambo726]

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.

Thanks Chuck, just ordered one today from Slice Engineering

[@Traderhood]

[@90sarcadefighter5]

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 👏

[@FilamentFriday]

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.

[@lynxxlynxx]

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.

[@JamesThompson-xl4yu]

I use the same finger ratchet you use. Good info and this will also work for ender 3 v3 se.

[@chadblows]

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.

[@damondarnell]

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

[@damondarnell]

​@@AkiraFurball 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.

[@svdworkis]

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.

[@losangelesrccrawlers3738]

Same, more issues after installation then before with stock setup

[@svdworkis]

@@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)

@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...

[@stevenc485]

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.

[@JoeMalovich]

I did this and am having endless heat creep jams where the filament slows down but doesn't stop all the way leading to underextrusion. I've done everything I can think of and research about to stop this from happening.

[@FilamentFriday]

Check your fan for failure( spinning too slow)

[@JoeMalovich]

@@FilamentFriday I had replaced the fan with a new one from creality (24V) as the old one had developed bad bearings. I have replaced my part cooling solution with the thingiverse thing# 3468243 sans fan guard but the problem persisted before changing the cooling. I also have the dual gear extruder (tuned e-steps), new ptfe tubing, and a hardened nozzle for abrasives. Hotend temperatures remain steady so it's not a PID issue and I used thermal paste between the heatsink and the cold end of the heatbreak. I have also tried setting retractions to 1mm without improvement. I am able to manually push filament out past the section where it swells up in the heatsink so I know i'm not dealing with swollen and stuck filament at the beginning of a print. No swarf clogs either. I have tried PLA and PETG from different brands. When I start the printer after a failed print and manually extrude it takes a 20-30 seconds of extrusion and stepper slip (not extruder slip) to clear the swollen section of filament from the cold section before the filament flows smoothly again. Yes I am using the slice engineering heatbreak you link to.

[@frits183]

Do you have a solution 🤔 i have the same problem 😟

[@JoeMalovich]

@@frits183 I just gave up on that solution and upgraded to a Hemera Revo. It is by nature all metal and they will soon be releasing hardened nozzles for abrasives too.

[@stuartpollock84]

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.

[@dangerous8333]

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.

[@FallOfInsanity]

Do you find that it helps prevent the gap clogs? Or does it still need to be super flush?

[@garylangford6755]

What issues did ir solve?

[@atistang]

@@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.

[@AndyDillbeck]

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.

[@jesseburson]

I can't use capricorn. Filament always seems to not go through it well. Ends up clogging at the end of PTFE

[@cache4pat]

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.

[@scottbroady7640]

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

[@infiniteefpv]

That means ur heat break ain't working very well lol

[@haysoos123]

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.

[@ILEFTCAPS0N]

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?

[@kkuenzel56]

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!

[@gustavrsh]

Why add the thermal paste between the heat sink and the break? Isn't the function of the break to NOT transfer heat to the heat sink?

[@fritzwalter1112]

In my case, I got a lot of clogs because of heat creep. The thermal paste between the heat brake and the heat sink helps with cooling the heatbrake

[@FilamentFriday]

The purpose of the heat sink is to draw heat away from the heat break top section so filament won’t preheat and expand. Thermal paste helps that process.

[@zajecar2420]

What about trianglelab one?

[@Medievalfan94]

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.

[@lakitu6422]

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.

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

[@NanceLvr]

Where is the firmware update?

[@24631]

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

[@direhavok8732]

Did you have to adjust setting of BLtouch using this item?

[@FilamentFriday]

I think I adjusted Z offset a touch.

Have you tried the dragonfly all metal hot end?

[@FilamentFriday]

No

Man I've been having a lot of problems with this thing. I I just can't get through a full PLA print without a clunking extruder and clogged nozzle. I'm pretty confident I installed it correctly but I think my base model ender 3 fan setup just isn't cutting it. I set my nozzle to 210C and used a meat thermometer (not sure how accurate this is in a hot end) and measured 52C where the Bowden tube ends and over 60C in the narrow tube going to the heat block. Manually pointing a 5015 fan at the hot end lowered these temps 15-17C. I'm also aware that retraction tuning is pretty important in metal hot ends, but my benchy with only 1.5mm of retraction started clunking an hour in. This was at only 185C. If anyone has suggestions or a similar experience with the base model Ender 3 and this part I'd love to hear about it. I have a supposedly better hot end fan coming tomorrow. I do believe this is a well engineered, well built component but I'm about ready to ditch it for the stock setup with a capricorn tube. I'll edit this comment if I can get it working. EDIT: Well, I hit a major SNAFU. The new fan performed the same as stock so I decided to rebuild the hot end and make sure I used enough thermal paste around the heat break. I managed to break the nozzle with the copperhead still attached, leaving my $30 heat break fixed to a useless heat block. I might try to extract the nozzle but I'm leaning toward just throwing my Ender into the nearest river.

[@FilamentFriday]

Sounds like a bad fan. It should get that hot. The 5015 fan kinda proved your theory.

[@papyro6830]

Online experts say a filament oiler is BS and a bandaid to improper assembly of your hotend. I disagree greatly, every jam,plug,and issue they create magically vanish with one installed. And after two weeks you can throw it away because it won't need it anymore. They need seasoned just like a cast iron skillet,its crazy easy and suddenly none of these issues happen at all.

Hi Chuck, do you remember where you got the stl file for the v slot extrusion covers? I remember you made a video about them but I can't seem to find it. Thanks. I've looked on thingiverse but I'm not finding the same stl.

@@FilamentFriday thanks for replying. I'm looking for a specific model, I am not sure but I seem to remember you featured one in one of your older videos. I've tried a few others but they don't fit as well.

i'd love to get one but it seems hard to find for my ender5 where i live.

[@truthteller5539]

Great review, I do have a question, did you have to reduce your retraction distance when using the bi-metal hotend.

[@FilamentFriday]

No, didn’t change it at all.

[@jeffaltavilla6261]

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.

[@FilamentFriday]

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.

[@jvianneyjr]

Could I use PLA into this bi-metal hot end?

[@lakitu6422]

My prints have a wood grain texture on them after installing this. Is there a way to fix this?

[@frits183]

Do you already have a solution 🤔 I have the same issue 😟

[@lakitu6422]

@@frits183 Sadly no. I've even tried asking on the q&a section of slices website and still haven't gotten anything. Best I got is that the boron paste didn't make a difference.

[@FilamentFriday]

Did you run a new PID on it after installing?

[@lakitu6422]

@@FilamentFriday Yes I did. Temps are only off target by up to +- 0.3 degrees afterwards so I'm not sure if it a temperature problem or something else.

[@frits183]

@@FilamentFriday I did now also and no big divererence I go try a other hotend and hope this will work

Are you recommending the Slicer engineering Heat Break over just getting a new All Metal Swiss Hotend?

[@FilamentFriday]

Yes.
