and one relay DPDT wired in a way that depending if it's on or off, reverses the poles of the spindle, connected to the other output.
I thought that in Mach3, I could set up a single output to rotate the spindle in both directions, just by setting one rotation to active high and the other to active low.
But in the motor setup page of Mach 3, I need two outputs, one for each rotation.
Is there a way to set up mach3 the way I wired, one relay just for on/off and the other to control the direction of rotation based on high and low, at the same port, or do I need to rewire the relays in order to have one relay to turn on in one direction, in one output, and another in the other direction, in the other ouput? And then wouldn't need the on/off relay?
Thanks for reading!
