Your video is the only one I found in TH-cam that solved the same direct driver extruder jam problem that happened to my 1 day old K1C. Thanks for this. You rescued me from having to pay for the shipment to send this back to China to be fixed. For my case the printer just printed bank (no filament comes out) after the 2nd print job after installation and calibration. I did not do any retract or pulling . The printer just jam on its own. Some comment on other web sites say this is a very common problem for closed door 3D printers. You can avoid this by monitoring the temperature of the cabinet. If it comes too close to 40 degree C, open the top cover or increase the Fan speed to cool it down while printing.
This is by far the best explained procedure I have seen online for dealing with the extruder. My filament jammed in the blue tube between the extruder and the nozzle. Not sure what made the filament expand and attached to it but with you video I was able to disassemble the whole thing and fix it. I sincere than you!
Thanks for the video! I was having problems with filament getting stuck and was able to take apart the extruders without too much issue. It helps to see the inside and find the issue (in my case the filament had expanded in the extruder before entering the hotend). Keep these kinds of maintence guides going, it really helps
Dropped on this vid, trying to learn what was causing my issue. Mangled filament inside my extruder was the cause. Thank you for a detailed and well explained solution, especially "watch for glued in place connectors...." I am tactile dysfunctional at the best of times, so that saved me a costly correction. Again excellent work, from a 1 day old maker's stand point, I couldn't of asked for a better guide!
Dude, you just saved me like 3+ hours of frustration. Wow, I almost certainly would have broken something trying to figure out why my brand new K1C stopped printing after the first test print. Back in business, thanks to your tutorial.
Best video that finally explained how it all works together. One point, my K1 Max has the LIDAR and therefore I could not find the screw on the left to take the cover off. I left the cover in place and just did my work with the extruder attached.
Great instructions, it got my printer working again. I took a short cut by just unscrewing the three extruded screws and carefully pulling the motor vertically. You have to be careful not to damage the stepper motor wires
Wish I'd done that. When I pulled the glue off the breakout board connector it brought one side of the connector with it and 3 wires popped out. Trying to figure out what type of connector I need to get to replace it. Benn through my JST set and not seeing anything similar.
Thanks for the video. I was able to remove the extruder assembly from the stepper without having to unplug the glued-in wires, which I was really reluctant to do. From there it was pretty much the same, process, except that the way the filament clogged in my extruder made it difficult to open, and I had to pry it. If the extruder casing doesn't open easily, just pry it open with a mini screwdriver, you won't break anything except the filament that's clogging it. As a point of critique, it would be good to point out that you can remove just the extruder assembly, leaving the stepper and its glued-in connector in place.
I had a small piece of filament rattling around in my extruder that got stuck in there when my filament spool tangled up on the back.. The glue was troublesome but with some time and patience like you said it comes off fairly easily just take your time. My extruder gears were extremely clean in comparison but overall with a little patience this is totally doable for anyone with good eyeballs
For the people coming here now, what is being suggested could very well temporarily fix it but the actual issue is that the hotend itself and the extruder, if you have one of the earlier machines, are faulty and they'll replace them for free if you ask and they're made of different things, they're better
Yes the first revision of the extruder is known to be a problem. This might help as you suggest but if you have a first gen extruder reach out to Creality for replacement!
why even updated extruder gears still plastic? isnt metal gears would be better? anyway to upgrade that gears myself? they are something standard like i can find in hardware shop?
nice video and I appreciate showing how to prevent the issue and just not fix. I ended up skipping taking off the front by just unlooping the wires in the back. that gave me enough loose wire to mess with the extruder without unplugging it. if it becomes more of a problem, i'll modify the printer head so the motor is flipped and accessibly from the back.
Thanks for making and posting this detailed outline!!! I had a different, and odd, blockage. The Extruder motor could not drive the gears. I could not manually move the filament inwards or outwards. After removing the extruder to see what might be going on, I could not disassemble it due to the filament still being inside, so I just "had" to use pointed pliers to 'leverage' agains the housing to get the filament dragged out. Then I could disassemble it fully. And inside there was NOTHING amiss at all. No shavings of filament or metal etc. It was all operating perfectly. But I could not see any reason as to why the filament had become "imovable", except by quite extreme force (leverage with pliers). But anyway, all is fine now, and you video made it easy to do all the correct steps to get there! Oh... I have the K1 Max, so you also need to remove the LIDAR to get access to the left front cover bolt. You only need to undo its two screws and let it hang aside there.
@@troygales9363 I have just had the same issue with a K1 Max. I was using the eSun PLA+ filament and they hook the filament onto the spool. So when it ran out the extruder kept going and wore part of the filament away and over heated the plastic in the nozzle, cooked it for about 4 hours. I followed the instructions, as above removed the lidar unit. I did not take the nozzle out but I did probe it with the long pin. Reassembled and its printing right now.
Awesome! Just saved my life!! I didn't have the guts to disconnect any cables so I serviced the extruder in the machine, dangling from its cable - still worked! 😂
Wonderful and useful video. I am having a difficult time removing the silicone boot that covers the excruder. You seem to just twist it and it came off, but when I twist, I afraid that I will damage the excruder. Any suggestion?
Thank you! Yes it takes some time to work loose... you have to very carefully pry it and pull on it especially after it has been through so many hot/cold cycles and if there has been plastic melted to it. It will take time, just be careful when prying with a screwdriver, you may puncture or tear it. Always good to have a spare or two on hand.
Hey, your advise was great to me. I am service engineer but for big Industry machines and this tiny Unit was a new experience for me. my K1 is back online and ready to print. Appriciate you help video very much. 😎 My mistake was to print PLA with ABS Tempereature and when I realized what happen, it was much too late and my nozzel and all other were jammed with blue PLA 🤯
Glad it was helpful! You might have experienced heat creep with the ABS settings where some of your PLA became soft inside of the heat break tube and then jammed. Glad you got it fixed though!
I had removed my extruder for a second for a clog.. for got if I needed to plug it in the top or bottom plug on the extruder motherboard.... Your thumbnail helped me! Lmao😊
is the k1 worth buying now after creality fixed the hotend/extruder issue?...planning to buy my first printer for my robotics project which requires a lot of iterative prototyping design
So far I've been having a really good time with mine despite this little extruder jam hiccup. I believe you can get the K1 on sale (right now?) for considerably less than a Bambu P1P so there is a lot of value here. Now I've never owned a Bambu P1P so take my opinion with a grain of salt... but from what I've read online if you have the extra $$ the Bambu printer might be a little easier to start with out of the box and they *may* have also worked out more of the bugs at this point. Generally you get a better price on the Creality machines but you also have to do a little more tinkering. This is all very general speak based on my experience in the past but I wish I had a a comparable Bambu labs printer to say for certain. You may also want to look at the Qidi printers. I have a test model I've been playing around with and they will be sending me a more refined version in September, but even their first model is very good and you get a bigger build area in the same price range as the K1 / P1P
Thanks for this, I was more interested in the disassembly I knew exactly what the issue was going to be I've had it before. I've just got my K1 Max and stupidly removed the filament the way you said not to remove it, oh well you live and learn the hard way. 😉
Thanks so much. Your video saved me! I am not technical but just following all the steps and not having a clue what i am doing or why. your video helped make something scary really manageable and approachable for me. thanks again for considering subscribing!
I've had this happen twice now before realizing I need to unload the filament more carefully. Both times the filament actually got stuck in extruder cover, not the gears directly. I wonder if a longer retract cycle in unload macro (to make sure the filament clears the gears) would solve this? Also, I just unscrew the extruder assembly, pull it out, and unscrew the extruder from the motor without unplugging it or taking the front cover off. Makes it a lot quicker.
Good idea about removing the motor separate, that's a nice shortcut. With the longer retract I don't think it's going to fix it though... I have a feeling the retract is long enough as it is but what is happening is that the filament path from hotend to extruder is very short, so when the retract happens the end of the filament is still hot and mushy... it's those extruder gears that are probably trying to pull it out completely but it's getting stretched and squished and deformed between the gears and the gears can no longer grip it to force it out completely. Longer retract won't help as you'll just continue spinning over the squished filament. This is my guess, but you can always try?
@EmbraceMaking That's a good point, probably not going to help. What I want to try (at some point) is to set a retraction in the end-print gcode or macro large enough to just clear the heartbreak, similar to what you would do on a Revo. This should at least help when you want to change filament when the nozzle is cold, so you can just pull out the filament without melting it first.
Lucky you, looks like you got the updated extruder design. I landed a early model that doesn’t properly tension itself. My k1 is a paperweight until creality gets me the upgrade kit.
The filament jam inside the extruder gear mechanism is caused by: The filament being too soft, hence, when the gears try to push it through the tiny hole, it blobs up and blocks the exit. Many factors can create this scenario. In my case, I am printing PLA on a hot summer day, and I also kept the whole printer enclosed. The ambient temp combined with the printing temps of the hotend and bed caused the clog. The solution for me is: Opening the top cover and door while printing PLA, lowering bed temp to 50 instead of 60, ensuring back ventilation fan is turned on an functioning.
helped me alot, when i pulled the motor, it had like a 5cm long filament stuck like a sword hahaha, if you had the same issue, try it with no fear, it isnt that hard, just be carefull with the glue
your video is very good and it helped me a lot, I could see where the problem is. when I removed the nozzle, it came out with a metal tube attached on it. And I it's cloged with fillament, like it broke inside. How can I remove that clog? I tried to heat up the nozzle and push it to force an extrude but it didn't worked at all and I can't pull it cause it's impossible to grab on it... Do you know how to solve this problem?
You might be able to push it upwards with a nozzle "needle" .... it is a very small needle that you insert through the nozzle and you might be able to push the filament upwards enough to grab it with some needle nose pliers
Appreciate the video, but I'm unable to tell the orientation of the extruder connector as it's in the shadows when removed and the video skips over the reinstall. Mine poped out, which colored wire goes on top?
I just bought the K1 and I had issue with extrusion. Only blue color came oup. Not filament. I think your way may help. but even though it is a new printer.
Hello, my issue has gone beyond a clog. I have a large clump of filament around the hot end and when I tried to remove it, I disconnected the lighting wire. When I want to know is, how can I clean all that filament?
Great video, I had a multiple jam disaster, both in the gears of the feeder , in the little feeder tube between the feeder and the heater and the nozzle was blocked too. Unfortunately I broke the heater assembly trying to remove the frozen nozzle, but I had the spare one that came eith the machine so hapy days, once that was out I could free the passage all through, however I did not put the big rubber texture gasket back. Its all working OK and that gasket was SUCH a pain to get off I am reluctant to put the new one back, any views??
Hello. I have bought the K1 about a week ago. I have unloaded filament only once, without unlocking the gears. And it seems that a piece of filament was actually left inside, like in your case. However, I inserted new filament and the printer worked well. Does it mean that the piece of old filament was extruded? Or it's still inside and may jam in the future?
Ok. I followed your instructions and removed the extruder which was clogged and also removed the nozzle, but after I cleared the motor and gears, I still got a piece of PLA stuck between extruder and nozzle. How do I take that apart/remove it. its not coming out at all and currently broken off at the base.
I bought the Micro Swiss hotend for the k1 max and also got the ruby nozzle but noticed it is different from the nozzle that came with the Swiss hotend. Will the ruby still work?
I've had 2 jams in a row now with PETG. Haven't yet resolved the 2nd one. The first one though, it had a thick portion inside the extruder locking the filament inside it. No clue why. Did not had filament swap after few prints prior to that. Environment is kinda hot due to weather atm. Any clue?
Hadn't printed in about five weeks, just left the filament sitting in the tube and extruder. Fired up the K1 Max and no filament will extrude. Going to have to disassemble and probably clean. When I run the steel push-through tool through the extrude the tip comes out covered in plastic so I'm sure there is significant build up in there. Any tips on actually deep cleaning a gummed up extruder? I was thinking an acetone brush down with a tooth brush but welcome suggestions.
I have a K1C and every time I try and change filament, I hit retract at 220 and wait for it to finish then unlock and pull out, but lately it has been frozen every time o try and remove it as if it was still locked in. I think what it happening for me is that when it heats and extracts the filament I think it is pulling molten pla out and then ramming it back into the barrel of the hot end flattening it out and making it impossible to remove.
@EmbraceMaking - My K1C is making a series of knocking sounds whenever I extrude/retract. Printer not extruding filament. I disassembled the extruder like you have shown to eliminate clogs/debris. I don't know what to do!
The knocking sounds like it is probably the motor skipping. Do you have a block in your nozzle / hot end? Is the clicking happening when there is no filament present in the extruder ?
@EmbraceMaking That's right. I came back to the printer running but extruding nothing. The spool was not empty. I then stopped it and proceeded to retract the filament to find a series of knocking before it finally ejected the filament to pull out, so that tells me the gears aren't slipping. The filament then seemed to be stuck, so I may have been a bit forceful pulling it while the lever was locked...
Any suggest on reconnecting the motor? I followed this video first and now I can't get into the tight space to reconnect the motor. You seem to have skipped the reassbley and all the other videos show it being done without disconnecting the motor
You can do it without disconnecting - but I had no issue reconnecting it. Just the reverse of the disassembly which is why I kind of skimmed over it. Usually I'll go into detail on the parts that are tricky or cause problems. The connector is small so maybe if you have some tweezers or something to hold it while guiding it into the plug it might help. Then use your fingernail or a flat head screw driver to gently push the connector back in.
Of all the 3D printers I've owned (4), whilst the K1 MAX prints lovely when its all working, it has to be the most awkward printer to work on, given that this is a task you may need to do several times during ownership, why is it so difficult and time consuming to change the extruder?
Troquei o hotend da minha pois ele derreteu o suporte me mandou outro mais ainda está saindo fumaça cheiro de queimado a capa de silicone do Hothend está derretendo acontecendo a mesma coisa q a anterior poderia me ajudar
Thanks a lot for this Vid! exactly my issue - and perfectly explaint resolution. It was even easy to work on (and that's coming from a clumsy one ;) thanks and greets from Austria, Mario
If you install the steel nozzle, is it a problem to print only pla or petg with it? Will print not often with other material or should you change the nozlle each time?
Hi, great video it helped a lot! at 7:02 you clear out the hot end, on mine i seem to have a blockage that doesn't allow me to pass the rod all the way through even with the nozzle removed. Any ideas how to fix? ive tried pushing it out and heating it up but no luck!

I have a feeling the retract is long enough as it is but what is happening is that the filament path from hotend to extruder is very short, so when the retract happens the end of the filament is still hot and mushy... it's those extruder gears that are probably trying to pull it out completely but it's getting stretched and squished and deformed between the gears and the gears can no longer grip it to force it out completely. Longer retract won't help as you'll just continue spinning over the squished filament. This is my guess, but you can always try?
@EmbraceMaking That's a good point, probably not going to help. What I want to try (at some point) is to set a retraction in the end-print gcode or macro large enough to just clear the heartbreak, similar to what you would do on a Revo. This should at least help when you want to change filament when the nozzle is cold, so you can just pull out the filament without melting it first.
Hi, very kind of you. Do you know if the extruder motor of the Creality K1 can be repaired? One of the cables came loose.
Thank you so much! Your video saved my K1C, my mind, and my day. Now I know my mistake when changing the filament. Thx!
Glad it helped!
Great instructions... 4min49 here that top plastic cover was stuck really hard, the filament was between that plastic and the gears
nice explaining with fantastic clear english ... Bravo!
Thank you! 😃
Fantastic video you absolute legend.
Glad you enjoyed it
Lucky you, looks like you got the updated extruder design. I landed a early model that doesn’t properly tension itself. My k1 is a paperweight until creality gets me the upgrade kit.
Did you ever get the upgrade kit and get it resolved?
The filament jam inside the extruder gear mechanism is caused by:
The filament being too soft, hence, when the gears try to push it through the tiny hole, it blobs up and blocks the exit.
Many factors can create this scenario. In my case, I am printing PLA on a hot summer day, and I also kept the whole printer enclosed. The ambient temp combined with the printing temps of the hotend and bed caused the clog.
The solution for me is: Opening the top cover and door while printing PLA, lowering bed temp to 50 instead of 60, ensuring back ventilation fan is turned on an functioning.
Thank you, your video is great for beginners still trying to figure out the kinks and clogs
Glad you found it useful!
helped me alot, when i pulled the motor, it had like a 5cm long filament stuck like a sword hahaha, if you had the same issue, try it with no fear, it isnt that hard, just be carefull with the glue
your video is very good and it helped me a lot, I could see where the problem is. when I removed the nozzle, it came out with a metal tube attached on it. And I it's cloged with fillament, like it broke inside. How can I remove that clog? I tried to heat up the nozzle and push it to force an extrude but it didn't worked at all and I can't pull it cause it's impossible to grab on it... Do you know how to solve this problem?
You might be able to push it upwards with a nozzle "needle" .... it is a very small needle that you insert through the nozzle and you might be able to push the filament upwards enough to grab it with some needle nose pliers
I just need to keep a closer eye on it. It made one good print and clogged. Works fine now.
Hope you've had better luck lately!
How do you remove the LIDAR camera to reach the left hand front cover screw?
Thank you...easiest video to follow....saved us!
Instructions very easy to follow and adapt to K1 max
Really happy it was useful!
Where can I get a replacement of the small ptfe tube at the 4 minute mark? Mine got a little kink in it and I think that is causing some of my jams.
Hello. What is the direction of the fan under the board?
Oh man I can’t wait to see the carbon fiber prints!
Coming soon! They'll probably hit my Instagram first because it's faster to post (or maybe TH-cam shorts?) So be sure to follow :)
Mind sharing what kind of screwdriver you were using? That would save a lot of time and headaches if I had one of those.
I cant remove the PETG from the extruder. Is it normal for my model K1?
Appreciate the video, but I'm unable to tell the orientation of the extruder connector as it's in the shadows when removed and the video skips over the reinstall. Mine poped out, which colored wire goes on top?
I just bought the K1 and I had issue with extrusion. Only blue color came oup. Not filament. I think your way may help. but even though it is a new printer.
Thank you, your video helped me fix my printer.
So glad I could help!
Thank you so much for this walkthrough. Saved my extruder! Subbed & Liked.
Thank you so much for your generosity and really appreciate the sub and support!
Hello, my issue has gone beyond a clog. I have a large clump of filament around the hot end and when I tried to remove it, I disconnected the lighting wire. When I want to know is, how can I clean all that filament?
Mine is working fine now after watching this video. Thank you
Great video, I had a multiple jam disaster, both in the gears of the feeder , in the little feeder tube between the feeder and the heater and the nozzle was blocked too. Unfortunately I broke the heater assembly trying to remove the frozen nozzle, but I had the spare one that came eith the machine so hapy days, once that was out I could free the passage all through, however I did not put the big rubber texture gasket back.
Its all working OK and that gasket was SUCH a pain to get off I am reluctant to put the new one back, any views??
Hello. I have bought the K1 about a week ago. I have unloaded filament only once, without unlocking the gears. And it seems that a piece of filament was actually left inside, like in your case. However, I inserted new filament and the printer worked well. Does it mean that the piece of old filament was extruded? Or it's still inside and may jam in the future?
If it hasn't caused a problem yet it will likely be fine. Don't worry :) if it ever does jam you at least know now what to do!
Adding my thanks for this video. Walked me through what would have been a scary and expensive problem to solve.
Yep, this video saved me a headache and a lot of time. Thank you so much.
Ok. I followed your instructions and removed the extruder which was clogged and also removed the nozzle, but after I cleared the motor and gears, I still got a piece of PLA stuck between extruder and nozzle. How do I take that apart/remove it. its not coming out at all and currently broken off at the base.
Thank a million! You saved my day. Exactly the same problem you had, now solved!
Awesome!
I bought the Micro Swiss hotend for the k1 max and also got the ruby nozzle but noticed it is different from the nozzle that came with the Swiss hotend. Will the ruby still work?
I have a brand new K1C and had mine jam. Had a small piece of filament in there. Probably forgot to lock the filament down.
Entirely possible - I just cleared out another small piece of filament that looked like it either swelled or was out of tolerance
I've had 2 jams in a row now with PETG. Haven't yet resolved the 2nd one. The first one though, it had a thick portion inside the extruder locking the filament inside it. No clue why. Did not had filament swap after few prints prior to that. Environment is kinda hot due to weather atm. Any clue?
Really quick question, where did you get that tool? (the hex driver)
Thanks for checking!
My extruder just will not come out, Im wondering if its stuck because of melted filament
I pulled it out, I always wonder what the retract function was use for
You are a lifesaver. Your video is gold.
Hadn't printed in about five weeks, just left the filament sitting in the tube and extruder. Fired up the K1 Max and no filament will extrude. Going to have to disassemble and probably clean. When I run the steel push-through tool through the extrude the tip comes out covered in plastic so I'm sure there is significant build up in there. Any tips on actually deep cleaning a gummed up extruder? I was thinking an acetone brush down with a tooth brush but welcome suggestions.
Thank you so much, this was my exact issue and this is my first filament printer ❤❤❤❤❤
Glad I could help! Enjoy your 3D printing adventure :)
I have a K1C and every time I try and change filament, I hit retract at 220 and wait for it to finish then unlock and pull out, but lately it has been frozen every time o try and remove it as if it was still locked in. I think what it happening for me is that when it heats and extracts the filament I think it is pulling molten pla out and then ramming it back into the barrel of the hot end flattening it out and making it impossible to remove.
I was unable to correctly plug the extruder back in
The pins on the female have bent, what do I do?
Very clear instructions and great video quality - thanks
Glad it was helpful!
Thank you so much for this video! It helped me a lot! Now I can back to printing 😎
This video helped me repair my printer 👍
@EmbraceMaking - My K1C is making a series of knocking sounds whenever I extrude/retract. Printer not extruding filament. I disassembled the extruder like you have shown to eliminate clogs/debris. I don't know what to do!
The knocking sounds like it is probably the motor skipping. Do you have a block in your nozzle / hot end? Is the clicking happening when there is no filament present in the extruder ?
@EmbraceMaking That's right. I came back to the printer running but extruding nothing. The spool was not empty. I then stopped it and proceeded to retract the filament to find a series of knocking before it finally ejected the filament to pull out, so that tells me the gears aren't slipping.
The filament then seemed to be stuck, so I may have been a bit forceful pulling it while the lever was locked...
Great video, thank you so much - We appreciate the details and tips to prevent.
Thank you! Really glad you found it useful!
Had the same issue and this video worked a treat. Thanks!
Any suggest on reconnecting the motor? I followed this video first and now I can't get into the tight space to reconnect the motor. You seem to have skipped the reassbley and all the other videos show it being done without disconnecting the motor
You can do it without disconnecting - but I had no issue reconnecting it. Just the reverse of the disassembly which is why I kind of skimmed over it. Usually I'll go into detail on the parts that are tricky or cause problems. The connector is small so maybe if you have some tweezers or something to hold it while guiding it into the plug it might help. Then use your fingernail or a flat head screw driver to gently push the connector back in.
Of all the 3D printers I've owned (4), whilst the K1 MAX prints lovely when its all working, it has to be the most awkward printer to work on, given that this is a task you may need to do several times during ownership, why is it so difficult and time consuming to change the extruder?
Thank you for that video! You saved my printer :)
Troquei o hotend da minha pois ele derreteu o suporte me mandou outro mais ainda está saindo fumaça cheiro de queimado a capa de silicone do Hothend está derretendo acontecendo a mesma coisa q a anterior poderia me ajudar
I'm really interested in what you are using for your electric screw driver, could you share what brand/model?
Sounds a bit like an adult toy, but it's a "wowstick" lol
Thank you so much I've managed to find the problem from your very informed video
Thanks!
Thanks a lot for this Vid! exactly my issue - and perfectly explaint resolution. It was even easy to work on (and that's coming from a clumsy one ;) thanks and greets from Austria, Mario
Glad you were able to get it done :)
nothing quite like having to disassemble my 500 dollar printer to get my heartrate skyrocketing
thanks for the help I was all jammed up on my k1c
Glad it helped!
I'm a little late to the game but... I'm here. Lol. Thanks for the vid, big help 😊
My filament is stuck in the extruder it won't retract out. What do I do
Thanks, you got me up and running again!
Thanks for this advice. I thought I had broken it!
If you install the steel nozzle, is it a problem to print only pla or petg with it? Will print not often with other material or should you change the nozlle each time?
No need to switch back and forth between nozzles. Print PLA, print petg, all with the steel nozzle
Don't unplug the extruder motor. Just pull straight up carefully so that the cables don't break. You'll still be able to finish the job
Did you upgrade your tubing to the capricorn kit?Has it helped?
I did but honestly not sure if I noticed much difference. It will definitely last longer though!
Does this also work with the k1C. I can't separate the plastic cover from the other half of the extruder after removing the m3 screws @4.50min
I have the same problem
It worked for me in the end. You just need to find a slim/sharp tool like a knife or sth. To get in between both sides @@areavisuals5261
Hi, great video it helped a lot! at 7:02 you clear out the hot end, on mine i seem to have a blockage that doesn't allow me to pass the rod all the way through even with the nozzle removed. Any ideas how to fix? ive tried pushing it out and heating it up but no luck!
Had the exact issue you are describing. The clog was inside the heatsink.
