The finer details

Metric & Imperial Inch support

Commander supports both Metric and imperial inches. This option can be easily configured in the "Operation" tab of commander under "Machine Units".

Please Note: Some aspects of GRBL controllers must be in metric, these include; Steps per millimetre, Acceleration and Max speed values. The good news, this typically only needs to be done once during initial machine configuration.

Spark Concepts xPRO V5 Support

The current version of Commander fully supports all of the extended features of the xPRO V5 including SD file handling, easy network setup and most importantly, network recovery!

Draw from scratch or import SVG, DXF and pictures, then create profile, pocket, V-carve and 3D relief toolpaths with tabs, lead-ins, nesting and tiling for CNC routers, laser engravers, plasma cutters and pen or knife plotters. It installs with Commander from the Master Suite download above, on 64-bit Windows 8.1, 10 or 11.
