Hi,
but what do you mean BoBs?
Sorry, it means 'breakout board', in your case the PMDX-122.
The fact that you can cause an Estop by hitting the button confirms that an input to the PMDX-122 is propagating
through it to Mach. Its a pretty fair bet then that the reverse is true, that is that Mach can communicate to the BoB.
We can test that.
MDI he following:
G0 X1
X0
X1
X0
X1
X0
That sequence would ideally cause the X axis to move back and forth one unit. What I want you to look for
is the LEDs associated with the X axis stepper driver. I would guess pins 2 and 3 are associated to the X axis,
and probably pin3 is the direction pin. With the sequence of moves I would expect the LED to light in one direction
but then go out in the other direction. Does this in fact happen?
