@1st_Kiwi_Nomad, I’ll present a counterpoint. For me, Mach3 is the gold standard of CAM interface. I’ve been using it for 10 years have my interface set up so I can read the X Y Z coordinates from 6 feet away, or through glasses + safetey glasses from a couple feet away. I have a clear display of spindle RPM, commanded and actual cutting speed, and I can adjust RPM and cutting speed on the fly to tweak the cut without interrupting the run as I monitor it. The X Y Z display is the most important as I edge-find and enter coordinates to set up the machining origin. Misreading a number in MeshCAM causes a little wasted computer time, misreading a number in Carbide Motion means at least ruining a workpiece, possibly damaging the machine.
