I have Z home enabled. X and Y are disabled. I have soft limits of +/-100,000. The input switch is not active.
I hit the Ref All Home button and the Z axis moves +.200 and stops. The Z DRO resets to whatever the initial value was. That is, if it started at -2.00, it travels .2, stops @-1.8 and resets the DRO to -2.00. No error message.
What am I doing wrong?
-
In Config >Homing/Limits, do you have a Home Offset of -2?
If so, then noise is probably triggering your switch.
-
The home offsett is zero. I don't think it is noise as the behavior is consistent. I can have the Z anywhere on its travel and have the DRO set to any number. It always moves +.2 and stops.

please attach your xml.

Thanks for the offer Hood. It was operator error. The button had the legacy DoButton code. I switched it to DoOEMButton and it worked.
-
Strange the DoButtons should work fine but as long as you have it working thats all that matters :)

It's running through a DSPMC. That may have something to do with it.
-
ah ok. Is it version 066 of Mach by any chance?

Yes, it is R3.043.066

Well there are known issues with it and homing, most likely when using external controllers. I have gone back to 056 or 057 .
