Thanks for this. Day two of K1C printer and this happened to me. This video was a life saver. I thought it was totally broken. I used a flat bladed micro screwdriver to gently pry the lid and body of the extruder apart once the crews were out.
Thanks! It wasn't as hard as it seemed actually, after seeing you disassemble everything I thought it would be really hard connecting all together later but it was actually easy ;)
Nice. I wonder if you might have a moisture problem with your filament. I don't have that specific printer but I know when I had a moisture problem I had all sorts of issues. Filament snapping in the tube and snags and bind-ups like you had there were pretty common. I recommend that you lightly lubricate those rods with some white lithium grease as well and keep them free of dust build-up so that you don't have issues. I let dust build up on my Ultimaker rods and moisture caused rust to form in a ring around one of the rods. I saved it before it started pitting but it was getting close to causing permanent damage. But if you keep those rods clean and lightly greased so that everything runs smoothly you shouldn't have any problems. Depends what sort of environment your printer lives in, of course, but if it's anything like mine was, dust build-up on those rods will, if left for a while, suck up moisture from the air and you could end up with surface rust in a ring around the rod where the dust gathers. It certainly surprised me when it happened to mine. I just lightly grease my rails every time I see any build-up now and I don't have to worry about it.
I have a couple of things I think may have caused it. It was very hot in my shop during this print. I had the top on and door closed. At this time, that is what I will contribute it to since it's not normal for me to do so, but I've had a lot of traffic in and out of the shop, so it was very dusty. I live in Florida and humidity screws with everything I do from painting, wood warping and moist filament. But, I always dry my filament before and during my prints. Before I had the dryer, that might be something I would have looked at. Those are great insights. Keep em coming!!
The cut at 8:05, how did you get the cover off? Another video on the same topic also cut and I can't get the top off! Edit: ah the stuck filament sort of blocks the removal of the cover, so it can be a bit difficult. I used a large flathead to pry it open.
Have it in the locked position and it should come off without too much difficulty. If needed, take a small electronics flat head screwdriver and gently twist around the seam to work it loose.
Here is my experience with this issue: It has happened to me 2 times. Both were with PLA filament. Both times it happened, was when my shop was abnormally warm and I had the lid on and door closed. Under the same temperature conditions, with the lid off and door closed, I have had no issues. That is with 50 days and 2 hours of total print time. So, I'm chalking it up to excessive temperature in the print chamber.
It happens quite regularly to me (about every 10hrs print with PLA), so I got quite good in unjamming it. Not sure yet why it happens so often. Changed both extruder and nozzle. I doubt it's the heat, but will keep it in mind. My guess it could also be Filament Quality and/or high speed printing....
Great, save me a lot of time. Thank you.

exactly the same
Thank for so much, this fixed it. Great work.

Working around the camera made it seem more difficult than it actually is. Glad the video helped you out!

cool
But why does this happen on the K1’s? I’d want to know before I put it all back together. Heat creep?
