I’ve posted a new Windows build of 3.1.1 on the S3 site. A user found a problem with computer-generated gcode that is conforming but Grbl Controller did not handle correctly in the Visualizer – i.e. it would not process spaces between an axis and value, so g0 x 0 y 0 wouldn’t work, but g0 x0 y0 would. This is now fixed.

Two other fixes made: Last line was being dropped in a file and stray spaces in an empty line would crash Grbl Controller.
