I’m glad you mentioned the last time it was easier when you took it apart disassembled. You can just take the two screws off to take the fan cover off and then the two setscrews need to be loosened and then the whole hotend slides right out
Hi, I just this minute removed a clog, and thank God it worked. I replaced the supplied spare nozel. It was still clogged. I don't recommend it but I just used a drill with a bit just under the size of the filament were the boden tube goes in and ran it through slowly until I felt no resistance put the Anycubic kobra2 back together and it works like brand new
You should always change/remove/add your nozzles while it's at temperature to minimize the risk of breaking it (the heat expands everything loosening it up.)
i got kobra 2 plus last week and had nonstop issues with the fliament tryin to extrude, i assume its cloged thanks for this video, i will attempt to fix it up tomorrow hopefully resolve this issue really would like to enjoy my printer!
Had mine 2 days..and it did the same. Your video encouraged me and I managed to get it working again. It had like a 5mm piddly little piece of filament that needed to be cleared... I couldn't believe such a small thing could mess the whole thing up so bad. One good thing tho is the replacement parts are super easy to get, and cheap as well. I do wish they were stronger tho. Thanks for the video.
Yeah, my Kobra 2 Max had a blockage that was catastrophic i.e. it ripped the wiring out from the control board and jammed the head under the bed plate because there was such a huge bulbous blob of filament it jammed under the build plate. I'm currently awaiting a new printer head (destroyed), and a replacement hot end (encased in solid PLA blob).
@@davidr5964 Sorry to hear it man, I also had that huge blob wrapping up my hot end as well. I heated it to 240(PLA) and it all just slipped off...including the silicon cover on the end. Which moulded itself into the PLA never to be seen again. I don't ~think they are necessary tho, so i don't really care. Luckily...I actually had 2 spare hot ends as I never trust a new printer, and had Amazoned a couple just in case.... Spent 1hr + then finding that piddly jam up in the feeding mechanism... apart from this.. I have had it running constantly with really really good results... I am at this point ONLY using Anycubics own slicer...and have had no issues so far. I do wonder one thing tho... in the book it says if I have a power failure..to simply press resume when the machine re-boots... this option I cannot find tho, and is a really pain in the a$$ as I am probably just going to use a UPS... but really shouldnt have to. SO far tho..after all this I am keeping it...at least I know how to re-build the damned thing now lol.
I have the Kobra 2Pro. Well, this is the second one they sent me after i had the same problem a week into owning one. About to send this one back too ig
I think my blockage is in the extruder as a i get a weird tick when retracting, is it possible to open that case and not have like a million little pieces come out?
Yes, look at the video. The wires may be able to stay connected when you clear the clog. I disassemble the unit completely to get a good look at the issue. The entire process takes about 20 minutes it's really not difficult.
Well, the first layer is an important layer. Try getting your Z axis to as close as a perfect height as you can. Run a leveling print, a few If you have to to make sure the first layer is laying down nicely. This can take some time, you will also notice that the nozzle height in Z may look great for one stl file but not so great while running another file. So fine tuning is key. If all else fails, then it's time to break out a file 😊

Thank you! I actually had to break the extruder in half. Plastic and metal gear. A chunk of filament easily jammed the plastic gear.

thank you so much for making this video

Great topic, thanks 👍

@@KWE.ECLECTIC know I know what I'm doing later 👀
@@thorrasmussen9792 Let me know how it works out for you.
Mine is doing the same thing, 1 week old did you figure out what needed to be done for a fix?
@@KWE.ECLECTIC It didnt help alot :( i think it might be that teflon tube or the nozzle instead, thanks for the video it was super helpful!
How do i get rid of those shit layers where the print comesinto contact with the supports

Hey thanks for not showing any of that pesky which screws to take off footage. Who needs that
