Convert a Mach3 CNC controller to GRBL or FluidNC
14 years ago I built my own CNC machine. At that time, CNC were running with Xp PC using parallel port. Gcode eaten by Mach3 software and sent to steppers controller board using the parallel port pins.
This machine, although dusty and rusty, still runs on an old PC... but it is time to design something more up to date.
This project is how I reused most of my setup and simply replaced Mach3 (and the old PC) by a modern laptop, controlling a FluidNC (GRBL) board via USB.
Project is fully described on my Hackaday's pages : https://hackaday.io/project/194302-convert-a-mach3-cnc-controller-to-grbl-or-fluidnc

And here is how all this is running with a "new" PC and FluidNC!
