I’ve been printing some utility tools out of Bambu Lab PA6-GF for a while now, but last night, ran into some problems, and am hoping to get some help as to what went wrong.
The first image is of a completely normal print of what I’m putting together. I’ve printed at least a dozen of these without any issues. The second one is a print I tried last night after drying my roll at 70C for 18 hours. The third one is the final print I tried immediately after the second print before canceling it. This was printed while the roll was in my Sunlu S4 while continuing to dry the roll.
Because of how long I dried it, I can’t imagine this is a moisture issue, but I’m not sure what else the problem could be. All of these were printed with the same settings across the board, using the same 0.6 Nozzle on each of them. I noticed a high-pitched whine coming from the hotend, which stopped when I unplugged the fan on the unit. But I don’t believe the fan is running during the print, so that shouldn’t cause a problem if there is something wrong with the fan, right?
Does anyone know what could cause this?
