I tried printing with PETG yesterday, and I noticed that it intermittently stops moving during the print for a few seconds. It doesn’t throw an error or anything, just stops and then after a few seconds resumes as if nothing happened. But this creates huge blobs where it stops. It only happens when printing PETG, not PLA. Could this be caused by a filament setting in my slicer? I’m using prusa slicer. I inspected the gcode and there are no stops, pauses or color changes etc. in it. The behaviour happens both when printing from octoprint and directly from SD card.

    I did some more testing, also with different slicers, and it seems to not actually be a PETG specific issue, but rather a model/speed issue. I can get it running without stops if I just reduce print speed. When I set speed to 100% I start getting these weird 10-20 second long stops.

    So now in thinking it’s the controller locking up because it’s overloaded by too many small movmeent gcode commands in rapid succession?
