RE: Keep getting a filament stuck message on my MK4S
Hello all!
I am working on an enclosure now. The last print showed extreme warping
I suspect somehow there is some draft hitting it enough. Despite brim and a clean sheet I get warps if I print over the whole sheet.
Certainly environmental impact. I rotated the print around to notice that it is much worse in other spots.
RE: Keep getting a filament stuck message on my MK4S
Hi, not sure if my solution is relevant to others but...
Short description:
Unload filament, crank up the nozzle temp to its max and see what happens.
A small PETG droplet fell to the build plate.. seems the "unload filament" process left a very small amount of PETG in the nozzle. Just enough to cause a sensor problem but not enough t0 block PLA flow.
Details:
I have an MK4S kit, no enclosure, 04mm HF nozzle, built in October 2024 and has been running practically non-stop with PLA.
I recently started printing in PETG, swapping back and forth between PLA and PETG. This weekend I went back the Prusament PETG to print a mod in orange, When I switched back to PLA, my next print had some very minor nozzle ripping of the the surface. I attempted to reprint (Multiboard large bin) several times, but repeatedly received "stuck filament" notifications within minutes of starting each print. Assuming the PETG swap was mostly likely contributing to the issue, I tried heating the nozzle, which eliminated the stuck filament problem.
This issue notwithstanding, I have absolutely no regret in my purchase of the MK4S... not even when my doggo absconded and chewed up some of my parts during the build. But that was all my fault for attempting to multitask, lesson learned 🤔 ... again 😆
Anywhoo, hope this info helps others.
Heating the nozzle to its max allowed whatever PETG that remained in the nozzle to drip out.
Printer is back in action, completing the failed print as well as other large prints yesterday (1/13/2025)
