I recently bought a CNC punch/nibble machine (Swedisch Pullmax P 210 dcm) The machine is 25 years old and is controlled by a TRS80 like homecomputer with Z80A processor. Working: The(steady) tool of the machine punches little holes and by moving the table it can cut out figures out of sheetmetal or aluminium. I would like to replace the Z80A computer by a Mach3 solution. I donít see many problems by taking over the control over the X and Y axes. But the punching tool is another issue. My question is: Is this done before and how do I control the punching movement?
