comment out the M92/A with a semi colon (which tells cnc12 to seeks the A axis switch) like this.
M92/Z
M26/Z
M91/X
M26/X
M92/Y

;M92/A

and the A axis will home where ever the A axis is sitting at. then you can debug general motion of the A axis first.

Re: Cant home rotary drive in the + direction, only (-)
Thanks
I had not been using the code you mentioned since I installed 4.2.0 with rotary plc, so the code is probably not a factor. I have been running find home from the soft keys.
I will try your suggestion. At least I can find a rotary home in both directions ??
I got the system homed as a 3 axis and ran the tuning before installing the new rotary software package.
The A axis seems to be operating perfectly. I assume that it would be better to home it somewhere and run tuning. Do you have published tuning parameters for it?
Did you look at my motor parameters table? I can’t find instructions to configure it, and am guessing blind. Please show me where to find instructions for it, particularly the A axis.
As to the wiring questions, it’s a brand new centroid 200 rotary which is wired according to the centroid CNC schematics. If it were wired wrong, it would not home in ether direction!
I have my own complete cad drawings which are linked below. Feel free to download the schematics and photos.
Thanks!!

Re: Cant home rotary drive in the + direction, only (-)
It sounds like your encoder counts are set wrong. Looking at your report they are set to 8000 but the new DC motors from Centroid have 5K encoders so the encoder counts per rev will need changed to 20000. What's happening now is it's seeing the home switch and then looking for the index pulse and not finding it within 8000 counts when moving in one direction.
