Hoping somebody might be able to help. I just completed a build of a scara machine utilizing some of the designs posted on this sight. I have the GRBL setup per instructions supplied throughout the site and the machine works really well with one peculiar exception. If I use designs with circles or arcs, it works perfectly, but any designs with long straight lines (ie the wipe/eraser design from sandify) each line will have a small curve inward towards the end (about 3/4 to the end) of the line. It is consistent and reproducible. The designs still look cool, but it kind of bugs me that the straight lines aren’t fully straight. Any ideas from anybody who has built these tables or used sandify for your gcode?
p.s. - I can post some video and/or pics if that would be helpful.
