Pause program execution, retract spindle, resume program

Hello dear LinuxCNC community.
I'm searching a way to implement in Gmoccapy interface next logic.

Use case:
As a user I want to pause execution of NGC program, then cnc machine should automatically go to predefined position (stop spindle) and wait
till I resume program execution. After program resuming machine should return to the paused position (start spindle) and resume NGC program.

Thanks.

That is not a gmoccapy problem, LinuxCNC does not support that.
You could take a look at "jog while Paused"
