Feedrate/Rapid/Spindle Override reset to 100% using a physical button

I know this has been discussed at length on other GUIs, but I was wondering what pins were available to reset overrides to 100%?  I have those little encoders with push buttons for resetting overrides to 100%.  I know in Linuxcnc 2.9 there are pins that are like feedrate_override.reset, but these are do not seem present in 2.8, which pathpilot is built off.  I was wondering if there was a good work around for this? Or is Pathpilot had other pins built in for this?  I know there's software buttons for this, I'd like to encorporate my physical buttons.

So if found the button in Python, how do I have a physical button call code in python?

I do this with keyboard shortcuts and xdotool. Maybe not as clean as something in python, but works perfectly and I use it dozens of times per day.

 

Could you expand on this a little bit? How did you assign the buttons?

this might work..in tmc/python/tormach_lathe_ui.py or tormach_mill_ui.py

look for this phrase..

# Escape used to stop certain UI tasks.
if kv == gtk.keysyms.Escape:
self.error_handler.log("ESC key - queueing stop event")
self.enqueue_button_press_release(self.button_list)
self.tool_descript_entry.shutdown_view() # if active terminates the tool description overlay
self.profile_renderer.update() # if active terminates a zoom view on the profile render
tooltipmgr.TTMgr().on_esc_key() # if active end the current tooltip.
return True

#w key on keyboard
if kv == gtk.keysyms.w:
self.sliders.set_slider_value(100)
return True

i use this addition for a jog encoder and spindle,feedrate,maxvel panel encoders...this version does need variables declaring earlier in the program but you might get the idea...

panel encoder send a keypress for each indent ...




sorry for pasting code but i can't remember how to wrap it!...
