ok thanks for keeping it simple jazz the estop is now operational from ground through spare contact to 0v on both the IP-S and the MPG module I then went a step further and put the ground (feed to the contactor) into estop1 on the MPG module and put ESTOP2 to ground as the MPG module ESTOP button opens the circuit then mach 3 knows about it,
but no because as soon as I push the enable the spindle motor spins, so I put the feed to contactor ground not through the MPG module and it works fine yet in the cs labs instructions it shows the ESTOP1 and ESTOP2 are just a switch, am I being simple and missing something?
the MPG is not smooth at all, is that for another thread??
