Pause function for use with a router

There are more than 8 example Sim configurations in 2.7. Each has a text file and there is an overall Readme with some instructions

See the directory:
configs/sim/axis/moveoff

More detailed instructions are at:

www.linuxcnc.org/docs/2.7/html/config/moveoff.html


Three is a manpage for the component:
www.linuxcnc.org/docs/2.7/html/man/man9/moveoff.9.html

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?

I haven't looked at it myself and don't know how it works, but hopefully it retracts to (or can be configured to use) a G53 machine coordinate position, there for making the position, offsets, and coordinate systems irrelevant when the retract is called.

I don't think it can do a G53 style move as that is part of the interpreter, this is a HAL only implementation, so as I understand it, it doesn't know about things like softlimits, workspace offsets etc.

AFAIK, you one of the dangers of this module is that you can jog into the hard limits of the machine ...

Some time ago ArcEye create a "hack" that make possible do this. There is a discussion thread on this forum somewhere...

seeing the video closely, the MDI can´t be executed randomly...

@rszemeti
did you find a working solution?
I would prefer the same function on pause as you!
