I have a exactly same problem, must be in g-code file. I have also another problem, part wing R1 is not fit an 220x220mm bed. Part is not printed in center of the bed, there is 2cm “margin” in left side.
I am having an issue with all there gcode files ever one is to the left on my bed by almost 60-100 mm off center. i have to hold my belt solid when its about to print to hope i get it started on the rigth side of my bed. is there an easy way to resolve the gcode not being placed on my bed correctly , software knows its 220×220 yet the gcode starts off centre
