X1C is the first 3D printer I’ve owned. I have had great luck with PLA and ABS, but PETG just gives me nonstop problems. Based on advice from others I’ve disassembled and cleaned out the extruder (did not have a jam in it), changed all kinds of settings, etc., but I still pretty consistently get junk like the attached pictures.
I’m using the PEI Textured plate, 0.4mm nozzle, and BambuLab brand PETG. I’ve dried the filament, replaced my silicone nozzle sock.
I’m under the (perhaps naive) belief that settings that work for someone else should work well for me, but everything I’ve tried has given variations on bad. I’m considering abandoning PETG and switching to ABS but would rather not because of fumes. If that’s the right answer, I’m willing and able to build a filtration system but seems like an extreme solution.
Anyway, can anyone share settings and/or point to a resource that helped them or worked well? This seems like a solvable thing, but I just don’t have the experience to know what to tweak or why.
On this particular print, I was trying out using PLA as the interface material for the supports, but looks like that failed here too (a bit spaghetti-ish). This was using stock Bambu Labs PETG Basic with the 0.16mm layer height profile. Only change to the profile was to enable supports, specify PLA as the interface material, and set the distance from top of support to next surface to 0mm.
