I have an old CNC machine that required a parallel port computer. Fearing that the old computer would eventually die, I decided to upgrade the CNC. I bought an Arduino and loaded GRBL into it. Bought some compatible motor drivers and a PWM spindle speed controller and hooked everything up. Now I'm using a Raspberry PI 400 with UGS to transfer GCode to Arduino, eliminating the old computer entirely. Next up: recycling laser cutters. :-)
