Hi Guys,

My machine randomly just doesn't calibrate. It make work for days or weeks and then sometimes I have to try 10 times.

The message: MARKER PULSE NOT DETECTED ON X Axis

I did some looking around and found this on Hurco site:
MARKER PULSE NOT DETECTED ON AXIS xxxx."
[FAULT] Î Encoder may be bad – requires “axis tuning” or “parameter
adjustment.” Telephone for technical assistance.

I can't find any information on how to "tune the axis". After a little research, I did find that the controller expects the limit switches to be a certain location (9 inches) by looking in CNC configuration. I'm not entirely sure what that means but I suspect that simply depressed the plunger on the limit switch isn't good enough. It's expected at a certain distance. Just not sure how.

One last thing, the encoder, that is inside the x axis drive or no? Not seeing it.

Thanks in advance for any help.
