Hi,
I'm a little lost as to what is going on here I don't know if the frozen touchscreen and pendant even have anything to do with it.
When using <FeedHold> the program is
paused, not
stopped. Mach at anyone time can have only one master....so in this instance
the Gcode interpreter is the master....even if it is paused, and so the pendant plugin will be ignored, as will the touchscreen or any MachGUI
control. If however you <Stop> the program then the Gcode interpreter ceases to be the master and the motion planner can accept a new source of
instructions, the pendant for instance.
