Sebastian, Hmm, I see what I have to do to create it. If I tie a signal to that output and disable the estop, it does correctly enable the associated amplifier. However, if I do the same thing with machine on, then main power is dropping out.
If I manually assert that output, I do not get the TRAM error, that only happens when it is tied to machine on. It might be as simple as reversing output_scale, as I have not determined the motor direction, only encoder direction.
