Hello
After about 6-7 months of trouble free printing, my k1c just crashed the print nozzle into the print bed after the 3rd layer and tore off the nozzle tip while also destroying the build plate with deep scores. I checked over the printer and found nothing loose, jammed or any obvious damage so i bought a new plate, hot end and nozzle (the force twisted the hot end and broke the temp sensor) I fitted everything, redone recalibration / input shaping etc… and ran about 4 prints of various sizes off successfully. 2 days later the exact same thing, destroying another plate but nozzle seems to have survived. I recalibrated, rechecked everything I could find using forum suggestions but alas a 3rd plate was destroyed, but this time at the 1st layer. Something is really wrong and its almost like the printer is forgetting or losing its position while printing. I have pics of the damage but don’t think I can attach them here.
I am at a loss, any suggestions? i have now lost 3 plates, 2 nozzles and 1 hot end (all origional parts) so i really cannot afford to spend anything more on it or its just becoming uneconomical to keep.
Havent contacted support yet as I want to make sure I have done what I can to resolve it myself, but could i put in a warranty claim if its over 6months but less than a year?
Thanks all
I will send them a email and try to start a warranty claim. Any idea what might have caused this? I appreciate that it would be difficult to say without seeing the printer or at least pics of the damage.
Pretty difficult to say. I’d have to suspect something like a loose connection with some of the control or motor leads. Lots of folks are printing with these, if it were a design or firmware issue, I’d think you’d be hearing more about it.
One thing to consider. If you’ve rooted the printer and added stuff to the configuration, there might be a problem there. That was one concern that I had rooting my K1C so I could run Orca, but so far no issues. That would be one area I’d consider however.
Thanks for the info. Printer is not rooted and is stock but as for something being loose it is a possibility as it does shake like mad when printing fast with hyper pla. I will check over and tighten every nut and bolt that I can. Cheers
As for failing around the 3rd layer, this was the first and second failure but on the 3rd failure it didnt even get to do the first layer. The calibration & nozzle clean did its thing, then as soon as the print started it just took lumps out of the plate. So maybe the strain guage is playing up / on its way out?
Just a quick update.
After taking the hotend appart and removing the rubber boot I found that the two screws which hold the hotend to the heaksink had worked loose and fallen out. When putting it back together I also noticed that the screws are far too short and there is barly two threads holding the hotend to the heatsink. I have now reassembled the hotend using some thread locker and tightened the screws as much as i safely can with out stripping the threads and so far i have ran off a few prints successfully. I will look into sourcing longer screws or even a hotend upgrade.
Been a couple of people the past few days that have too short screws and screws that have come out. Definitely get some longer screws. I had to put longer screws on my Ender 5 plus hotend as that fell apart once and the nozzle dropped onto the bed.
I haven’t replaced any of those screws, but I did notice they could have been longer and probably should be. I was a bit surprised that there wasn’t that much engagement with the extruder/hot end screws as well. Maybe time to grab my screw box and adjust that deficiency.
