Thanks the advice guys. Ok, i guess i should avoid mach 3 then and i need a board that is suitable for linuxCNC

The only issue is that I'm not going to buy an old computer with a parallel port. Can i get one that will work from USB or Ethernet?

Maybe i could use a raspberry Pi and integrate it into the machine but can i use a Raspberry Pi for LinuxCNC?

My 125TCL does not have a tool changer, its a pretty basic model but everything seems to work in manual mode except 2 of the axis control buttons don’t work.

I guess someone on here could make use of the old parts once i have converted the machine?
