Since I am currently running the 2.6.0-master-rt, can you share the .hal changes to do that? And I know there is a debounce gizmo I have not studied yet, can it be made suitably slow at going back false only? Or perhaps there is a re-triggerable one shot module? That would solve another problem now requiring a G4p1 to solve in the gcode. That may not be the correct method for that, so I'm all ears on this. Thanks Ben, useful info indeed.
