    Hi,Maybe you solved it and maybe i'm too late, but it might help someone :If your step/mm are not the same on X and Y ($100 and $101 in grbl), get the ratio between steps/mm X and step/mm Y.Then you can go in the arduino program, change const float stepsPerPixel; into :const float stepsPerPixelX = 8;const float stepsPerPixelY = 10; Here 8/10 match my X over Y steps/mm ratio, but you will have to change accordingly.At the end of the document, put your stepsPerPixelX or stepsPerPixelY where you see stepsPerPixel written (use ctrl+f).depending on the kind of move. You will now have a scaled X and Y :)
