I have had no problems with my BambuLabs A1 (with AMS lite) for the most part and generally love it. But for some reason this last, simple 1 color, one object print started doing something weird. Every 20-30 cm of line printed it goes and purges. (See picture, where it had only printed a short line and then went to purge. See all those white poops? That’s from a previous attempt where it stopped repeatedly to purge, similarly.) It does this repeatedly. Although I’m not an expert in 3D Printing I can’t think of a reason a printer would be doing this? (The print seems to come out fine if I let it do it’s thing, it just wastes a LOT of material and takes much longer than it should.)
It’s PLA, BTW.
Did you slice the model? It will only go to purge when it gets the command, so the command in the Gcode. If the original model contained filament swaps, but you just set it to use the same color without removing these filament swaps, then it will still go purge like you describe.
