Motor driver board for CNC Machine L297, L298 author conducted with integrated 3 axis control circuit for each engine used. LPT parallel port that communicates with the computer is done via the ULN2803 circuit and built on PC849 opto
For controlling the motors I’m using a chopper controller that works with L297 and L298 ic. The components therefor I’m going to pick up a few control print I received (see below). Rik The reason that I do not use print as they are is because if you adhere to a stepper motor that immediately begins to turn and the steering is not really universal.
