I am having a problem with the spindle motor encoder on my cnc mill. I am not getting an actual RPM readout on the KMotionCNC GUI and I can't get the rigid tapping to work with Morrays code.

The encoder is wired in to channel 3 (KFLOP+KANALOG), the settings are correct in the Trajectory Planner tab in the tools menu of KMotionCNC (they were working a year or so ago before I updated the software). I can see the inputs Enc 3 A and Enc 3 B change state as I turn the spindle by hand (on the Digital I/O) screen of KMotion.exe and axis 3 is enabled in the Axis screen.  But I get no encoder counts on the Axis screen.

I am not sure what why its not working. I swear it happened when I did an update a while back but I can't tell you when one. I seem to remember it being around the time of the first screen editor, but I could be wrong. I am currently running 4.34i.

Thanks

Dan

Hi Dan,

Axis 3 is configured as No Input. It should be configured for Encoder
Input Mode.

It also does not need to be enabled in order to monitor the encoder.
Encoder position is monitored whether or not the Axis is enabled.
