OMG! 😱 This 3D Printer Hotend is a Nightmare! 🔥

[@flex2flex640]

Installed it on my ender 3 v2, had to cut and strip the wires which was the worst part but it worked it flawlessly. Heated up fast and printed without issues. Prints looked better as well compared to the stock hotend. Happy with my purchase.

[@ThePrintHouse]

Glad to hear! Sounds like youre one of the lucky ones :D

I was having all kinds of thermal runaway issues wth this Hotend. A friend of mine suggested that it was a loose wire somewhere. So I resoldered the connection and that didn't fix anything. but I forgot that there are 2 connectors in this. I was able to seat the wires in the connector for a better connection and now it works perfectly. I recondment that you solder the extension cable to white connector and remove it. only leaving you with one connector.

[@williescraftscorner1467]

Love this video, it highlights the many issues I also have noticed with this hotend. I've run the same hotend for 2 months. First month went well, now the past 2 weeks, I've been getting random thermal runaway on my modified ender 3 pro. As an electronics enthusiast I have resoldered and measured every connection. And it seems there's a loose connection that's causing these issues within the ceramic heating block of the device. Given how many people seem to experience similar issues, I'll guess this is a major quality control issue going on right now.

[@ThePrintHouse]

Ill take it one further. This is a 5 month old video and the problem existed then so I think this is a problem that always existed and hasnt been corrected, so I doubt it will be corrected.

[@williescraftscorner1467]

I agree, feels like they have zero interest in resolving this issue. I actually took the device apart and could conclude the issue is inside the ceramic heating block. Will be filing a warranty complaint and hope for the best. Or maybe a refund.

[@andyspoo2]

I have had one for a few months and it works well. For one, don't use the steel nozzle it comes with. PLA loves sticking to steel more than it likes sticking to the bed. Secondly it looks like you have selected the wrong thermister in your firmware so the reported temperature is wrong.

[@802Garage]

I believe the included nozzle is nickel plated copper. It's a Creality MK-HF nozzle.

[@redcargarage]

I believe most MCU disconnect errors are caused when electrical noise gets into the cabling between your printer and raspberry Pi. Specifically a cheap USB cable which runs close or parallel to stepper motor cables or heater cables. Confirming the body of the printer is grounded properly is an easy first step. Next is using a higher quality USB cable with better shielding and ferrites, and keeping it away from other cables as much as possible. The raspberry Pi should be moved away from the printer as well, not put inside or under the enclosure. My guess is the cables from the ceramic heater put out more electrical interference for some reason - maybe they aren't being grounded the same way since the heater is ceramic instead of metallic. But I'd be willing to bet you can make it work with a better USB cable that's routed away from other cables. This is a common issue in industrial settings.

[@Roadified]

I was considering this for my ender 6 too. But now not really . What about the previous Spider Pro (v3) model?

[@fionoz9586]

The v3 is really nice. Got upto 40 mms3 with a cht clone. I got it on a deal for 14 dollars lol.

Ty for this vid. Had this in my cart & decided to check vids 1st.

[@sbtoonz1358]

I grabbed one of these at microcenter. It took a little to fixup my pressure advance . Other than that its been a great replacement for the stock hotend, You just need to go through your extruder config change your hottest temp to the 300c that the hotend is capable of I have put over 80 hours on this hotend so far printing ....

[@ThePrintHouse]

I think there is manufacturer control issues. When I move I do plan to revisit and test this all over again.

I'm using it right now. It prints very nice,. Printing at 100 mm/s in cura on an ender 3 v2 stock extruder. PErhaps i need to replace it with an orbiter or such to fully extract its potencial?

[@Robert_Monitoruj24]

I have a problem with setting the temperature. PID doesn't help It does not heat the nozzle during printing. Still missing 10*C The standard HOTEND works without any problems. Spider 4.0 works beautifully except for this E1 temperature error

[@BH4x0r]

you need to change thermistor type in firmware

[@kittt_out4979]

Installed this hot end, at 250mm/s the max temp i able to achieved is 205C. Very disappointing

[@CapacitorCapacity]

Hotend in the K1 causes the same MCU disconnects with the same erratic 5 second to 45 minute timeframes. I have the same "i cant trust any single print to finish" feeling. What I noticed is that when disassembling the hotend there was next to no TIM applied between the ceramic and the throat and what tiny bit of TIM was there was the driest most crumbly awful bit of TIM I have ever seen. This causes the ceramic element to have to heat way too hot for way too long to keep the nozzle at temp. Its operating inefficiently because not enough of the heat being generated is moving to the thermal mass of the throat and nozzle. Eventually this causes the heating element to burn up but it also causes the inexplicable "I'm pumping so many watts into this heater and the nozzle isnt responding quickly enough wtf is going on" errors that I believe cause the disconnects. Im very curious to see if you disassemble these hotends and reapply TIM properly what sort of results you have, presuming the heating elements havent burnt up too badly.

[@ThePrintHouse]

Incredibly detailed and helpful comment. Thank you. I'm incredibly packed with projects but I really want to try this. Not sure if I'll be able to squeeze it in but I'll try. What TIM do you recommend and did you have any significant issues taking the hot ends apart. If they're burned up is it obvious? Do you have any tips or video to share that can help me identify if they're long gone and burned up?

[@roccocroce]

more on ths pleaseeeeee

[@diogocoelho496]

could it be because is not responding to the old PID tune on klipper ? i had those issue when removing the nozzle hot and also klipper says when intalling a new hotend the PID tune needs to be done again.

[@ThePrintHouse]

Trust me that is what I was thinking the problem was, but it wasnt :/

[@diogocoelho496]

@@ThePrintHouse maybe its the desing of this hotend that is not good. the heatblock looks like is attached with the heatsink and the heatblock gets cold by temperature tranfer of the heatsink to heatblock cause they still toghetter with the same material, also they added fins to heatblock where is a place that needs a silicon sock for temperature isolation not dissipation like they did and i think is that what cause the problem cause no other hotend brand puts fins on his heating blocks.

[@MrBaskins2010]

People basically stopped talking about this hotend like six weeks after it dropped lol I forgot it existed until I saw the thumbnail to this video. The real issue with creality printers is the extruder. Titan extruder is an upgrade I do on every single printer from day one

[@BH4x0r]

lol so there are still people using titans? dang

for my curiosity, what is the difference between this ho end and the Spider V3 (3.0)? I am looking into upgrading the S1 plus with Klipper, cooling and a new hot end and was leaning towards the Spider 3.0

[@ThePrintHouse]

Honestly I am not 100% sure, but this hotend has the higher flow of the spider line up.

[@jrbenito5983]

Wouldn't the MCU disconnect be related to power supply issues or the mainboard being incapable of delivering so much current to the hot-end? If any of those two components are squeezing to power the thing, the MCU will suffer from brownout (lack of energy) and reset causing the klipper to disconnect. The randomness you described and the fact that the new hot-end is, probably, more potent than the Ender 6 stock leads me to believe that it is a power supply/mainboard issue with the current demands.

[@ThePrintHouse]

I'm trying to think back to this nightmare of events.... I don't know if I checked peak amps driven from the power supply... When I move to a new studio I plan to revisit this hotend and see what I can do. I would be surprised if the power supply isn't good enough though because this is rated to be a drop in replacement for the ender series machines.

[@rackbites]

Did you use the thermistor supplied with the hotend or did you just use the one from the existing one?

[@ThePrintHouse]

I used both for various tests.

[@kyled5667]

Just installed this on my printer and its been a pain in the ass. Won't heat past 185 C and eventually errors out. Thought it would be eventually less work than my Micro Swiss that I was getting annoyed with. I had updated the firmware etc still no go. Hoping Creality will replace it or refund it. Hoping I can get one to work.

[@Doktor_Calamari]

I find that I have to run a PID before I change temperatures--or else run a PID to the highest temperature that I plan to print at. I noticed that the temperature would rocket up to 10 degrees below target, then stop to avoid overshooting. It would waver at around 10 below target... and then eventually make it past this threshold and reach target temp. UNLESS, that is, Marlin's heating watchdog timed out, and reported a thermal error before the "waiting/stabilizing" period was over. There are probably ways to modify the PID tuning parameters to avoid this "fear of overshoot" or extend the watchdog timer, but I haven't figured that out yet. I'd really like to eliminate the waiting period, as it obviates the Spider's fast initial heat-up. My main problems with the Speedy Spider at this point seem to stem from its unusual full-length heat sink. I use a Petsfang duct, and with the teensy sock, the increased airflow seems to cool the hotend. In fact, when the silicone sock became dislodged, the nozzle dropped below flow temperature, and the extruder started grinding PLA! I replaced the sock with a tiny slice of silicone tubing--Creality, please give us replacement socks!--and the filament started flowing normally. However, I still have some layer adhesion issues, AND the tips of my PETG Petsfang duct got too hot at some point and melted! I've just had some much more successful prints at a .12mm layer height (I usually use .20), so maybe that's the solution for my set-up, but I think a more conventional hot end sock would help "keep the hot side hot and the cool side cool," to quote a decades-old McDonald's ad.

[@MasterBlud]

you neeed to bring down the retraction distance\

[@MasterBlud]

You needed to bring down the retraction distance to 5 and do your pod tuning.

I got my mine today. I installed it. Began heat to purge...went to temp then died. Would not reheat - Period. Immediate return. **EDIT UPDATE** I have installed a Spider v2 with a 60w 24v heater. AMAZING results. I can only guess it will get better with Direct Drive. If you try this ensure to run a PID temp calibration, I just wrote in notepade turned into a .stl and ran on printer, worked well.

Thanks for your reply also, much appreciated.

[@ThePrintHouse]

@@nickoblicko7046 Well, to be honest, your best bet is to use the stock hot end. There are not enough ender 6 mods readily available that are easy to do. I print PETG on PTFE lined hot ends very regularly. I just have to replace the PTFE every 250 - 350 hours of print time. As for Replacements, honestly because there are so few bolt on upgrades for the ender 6, I cannot recommend anything specific. If youre dead set on all metal hot end, I am almost more inclined to recommend you sell the ender 6 and buy something cheap like the ankermake m5c or some other new creality ender 3 variant that has an all metal preinstalled. You can look into the sprite extruder, I think someone did that upgrade for the ender 6 but I dont think it is heavily documented.

[@MrBCRC]

The smarts for the hotend is a heater and a thermistor. It doesn't get simpler than that. This is a klipper bug. Kilpper is throwing a totally unhelpful error code and you're blaming creality. Klipper needs to be fixed to tell you if it was the thermistor or the heater element that it doesn't like.

[@MrSh1be]

I fixed that by re connecting the thermistor connections they suckkk

[@GuidoHendriks1990]

How can you spend 40-50 hours on a defective hot end. 😂

[@ThePrintHouse]

I spent 10 hours debugging, designing, iterating on design, fan flow analysis, and printing a fully custom fan shroud in order to have this hot end actually fit inside of the ender 6. Then about 1-3 hours rewiring the printer and hot end. Then another 1-2 hours settings up the printer config file for the hotend + new bl touch mount. Then SIGNIFICANT issues with clogging that first took up 5-10 hours. All to find out a hardened steel nozzle installed from factory. Incredibly low flow rate causing immediate clogs. I was dealing with that issues in parallel to the MCU disconnects so half the time I tried to fix the clogging I had disconnects. In parallel with those issues and while I was attempting to create a refined cura speed profile I was dealing with the completely unrelated (to the hotend) issue of cura 5.3 bugs causing ugly blobs on models which nullified every slicer modification I made. When I began to tackle the mcu disconnects I had 5 hours of research spread across the last 2 months. I spent 3-5 hours FULLY rewiring the ENTRIRE ender 6. I wired in new motors. I checked for EMI on nearly every E6 component because of the brand new rewiring in case that was causing something to cause a hardware shutdown causing MCU disconnect. I discussed the issue with many other people across multiple different posts on reddit, emails, as well as in person meetings. More rewiring when I resoldered components to check for bad soldering joints. More rewiring when I attempted to install a brand new unit to check for factory defects. Honestly the list goes on. The hours add up. I tried to hard to make this hot end functional, but across multiple units it simply wasn't. I wish I could give you more examples of things I tested, but I dont think you really care. Youre only here to troll :/

[@JonLaRue]

I too someone who will spend hundreds of hours potentially trying to make something work.. It's pretty synonymous with ADHD hyperfocus... On my Ender 5S1 that was defective I spent at least 150 hours trying to fix and documenting all the problems with the machine. I lost a lot of sleep for no good reason other than that's what my ADHD called me to do... I have a feeling the presenter also could not sleep and just had to try to fix this as much as possible. Just want to let you know dude, thanks, and it's not your fault, Good work

[@JonLaRue]

I am back... and I am here to say I have spent 120 hours of my time working through a hotend issue, triangle labs CHC Pro Hotend with Klipper. Having same issues.

[@BH4x0r]

​​​​​​@@JonLaRuethese are very high power hotends, especially the CHC Pro that means you may actually want to check if you're not overloading the PSU, especially since the E5 has a 500W PSU, the bed itself is like 350-400W and the stock hotend is 40W, that leaves little left for the steppers now replace that 40W hotend with a 100+W one and you can see why i'm saying to check that, that printer out of the box/stock has very little headroom on the PSU besides that you could also add a small 10uF capacitor (rated for atleast 30V, ensuring polarity is correct) on the hotend output aswell to reduce switching EMI, that wouldn't hurt things but maybe reduce EMI and also work against inductive kickback (~5-6A through very long wires, worst case scenario voltage peak on turnoff could reach that high it blows your mosfet)
