This is a resonance test for the Rigidbot 2 to isolate the cause of XY vibration on curves. In the photo, the yellow print is exhibiting the resonance. The black print is on a different printer and does not have it. The cause is as yet unidentified but it seems to be related to curves only. The Gcode files are for ABS @ 245C on a 10x10 bed, so change your hot end temperature to suit your material and printer after starting, but don't use these Gcode files for smaller printers. Reslice the STL for your printer if it's not at least 8x8.
