Thanks! A stupid question - what dimensions are the BED_SIZE parameter, millimeters or steps?Quote
Dust
3200 should be correct but it is is a lot of steps / mm for a old 8 bit controller.
I would definitely change it to 1/8 micro stepping and set 1600 steps/mm
you will need to reduce the X and Y DEFAULT_MAX_FEEDRATE { 300, 300, 5, 25 } // X,Y,Z E
See how Z is way slower, because Z is a lead screw (or threaded rod)
