The Foxalien Vasto is a cnc router, featuring linear rails and ballscrews, which is capable of milling aluminium and steel.

The Sainsmart PROVerXL 4030 operates in negative coordinate space and lightburn expects it to operate in positive coordinate space. Without the correct grbl configuration lightburn will send the axes to the wrong locations.

These are the the setting that I downloaded from a new unconfigured Sainsmart PROVer GRBL control board.
