3040 CNC – Finding a Replacement for GRBL!

In this episode, we will be looking at a replace for GRBL and the CNC Shield as over time I have start fall out of love with GRBL or maybe more so the embodiment (i.e. te UNO & Shield) of it all and feel the need to grow a bit. So I went exploring found several options (see links below). My plan is to wire this into my 3040 (possibly also upgrading to a 3060) as well as want to move to ture 4 axis work (not just swapping X). So the journey is starting!
