Hi I'm planning to wire my limit and estop switches to a relay that will cut power to the spindle, disable the stepper drivers and inform Linux CNC that an estop has occured. I want do this this as otherwise there may be no way to stop the machine if a software error occurs.
This means I will need a limit override switch so I can jog back off the limit switch. If I feed an output from this switch back into the PC is it possible to limit the maximum jog rate while the button is held in, so I can't accidently jog at high speed in the wrong direction? I'm not looking for a full solution just confirmation that this is possible to do with HAL commands. If possible I will set myself the challenge of working out how.
