I have been designing, building and refurbishing machines for over fourty years but I now would want to get into CNC retrofitting as a hobby. As a mechanical engineer the mechanics is no problem but I lack a great deal in the electronics field. The computer/drive interphase is my biggest stumbleblock. I have recently bought a welding robot without controls and would like to get it working as it already has all the stepper drives and mechanical movements.
