Elephant foot? Nozzle cleaning?
Hi,
I just printed a part of a box and have two issues:
1) I printed it in white PETG. Unfortunatley I printed something red before and thus I got a light pink first layer. Probably I need to run a longer "first cleaning line". But is there somewhere a setting in the slicer?
2) The lower part of the box is a bit wider. Looks like an elephant foot. But it is not directly at the first layer, because there is a fillet. So I am unsure if this is may be a different effect? What do you recommend to avoid it? The elephant compensation in the slicer is already set to 0.2.

1) the purge line is part of the initial g-code, you can modify it in slicer: Start g-code in printer settings. This is the longer line used for MMU:
; purge line G1 X55.0 F2000.0 G1 Z0.3 F1000.0 G92 E0.0 G1 X240.0 E25.0 F2200.0 G1 Y-2.0 F1000.0 G1 X55.0 E25 F1400.0 G1 Z0.20 F1000.0 G1 X5.0 E4.0 F1000.0
2) probably "bulge line" due to change of infill - difficult to say without the project file.

Yes, bulge line due to a change of the infill could be a good reason. This part is a box and at the position where it happens the bottom ends and the walls start, see also the attached file showing a section view.
