How about adding two more small, cheap ($3?), front panel encoders? They're always there, and they're always on. No switching around. Here's how Stuart's Cinci 5-axis lists it: # Spindle Speed Over Ride net SPOphaseA encoder.2.phase-A ppmc.0.din.32.in net SPOphaseB encoder.2.phase-B ppmc.0.din.33.in net SPOcounts encoder.2.counts halui.spindle-override.counts setp encoder.0.x4-mode false setp halui.spindle-override.scale .00254 # Feed Rate Over Ride net FROphaseA encoder.0.phase-A ppmc.0.din.35.in net FROphaseB encoder.0.phase-B ppmc.0.din.34.in net FROcounts encoder.0.counts halui.feed-override.counts setp encoder.0.x4-mode false setp halui.feed-override.scale .05 It even uses PPMC DC input bits (you're welcome, Jon).
