MPCNC part 7

June 9, 2023

When cutting 6mm HDPE in a single pass, I experienced lost steps and a glitching sound when steppers were kept enabled after the job had completed:   GRBL is arguably better suited to CNC milling operations than Marlin (position updates during arcs, better compatibility with CNC.js).
