This particular machine is a simple single head machine with a servo-driven Z axis, nothing complex. It's a retrofit after the ancient controller on it lost it's init code. EMC seemed like the best option to get the servos up and running in closed loop.
I would prefer a single-button solution as when things go wrong and you quickly need to pause the job, that's when you are going to forget the second button.
Is there a way to find out if that code linked above made it's way into 2.7? or did it work it's way into MachineKit?
I don't really understand how to hook up that "moveoff" thing to do what I need. I guess I can skip the GUI as I don't need that, so I'm guessing I hook this "moveoff" block up in the Z axis and trigger it to retract the Z just after the pause button is hit?
The "z_retract" example looks like it might work, one question ... if the retract distance is pre-set and you bang the pause button when the axis is already fully retracted (eg when moving between fixtures) ... what happens then? out of limits error?
what I was wondering is if there was some way to feed the pin that has the value of the retract distance with the distance the joint is currently from its zero position
so sorta
joint.2.position -> x by -1 -> feed into z retract distance pin
would that be doable and make it retract just the right amount?
