I wonder if someone could offer some advice on hal configuration for a DC motor which is wired via a H-bridge and used to position a plasma torch.
The motor was originally driven by a torch height control unit which had an initial height setting, but there is no encoder or any sort of feedback from the motor/lifter assembly. So, this must have been done by finding the workpiece and then turning the motor on for N milliseconds to retract the torch to piece height. My question is, what hal components can I use to achieve the same? I'm guessing pwmgen would be used to drive the motor via the H-bridge, but how to connect this up so that you can jog Z position in Axis and set via G code.
