I have been watching the Wiki and reading about the possible interfaces, but would need some initial guidance on deciding which physical interface to use, since I have no previous experience in this area (Parallel, MESA PCI-card, which MESA ?.) I have been able to identify the pinout of the controller and realised that the Pulse and Direction signals for the steppers are 2-wire RS422 differential signals and the rest are single-wire 5V signals. I would like to use LinuxCNC on this machine, replacing the handheld controller by a PC equipped with LinuxCNC, but maintaining the interface board so I can switch back to the handheld controller when necessary. The handheld controller is connected via a 50pin cable to a board that interfaces the controller to the stepper drivers, the VFD for the spindle and the X, Y, Z limit sensors. Currently it is controlled by means of a handheld controller which reads the G-code programs from an USB stick (Richauto A11 DSP controller). I am using a 2nd hand CNC Router with stepper motors. ![]()
