How to use

Draw your design in CAD software. i.e. Fusion360
Create toolpaths including feed rate, depth of cut in CAM software i.e. Fusion360
Export the toolpaths from the CAM software as gcode using GRBL postprocessor.
Check that the cut bed is clear of clutter.
Mount your material to the cut bed with wood screws.
Turn on the router by switching on the "Main switch"
