Andy,
I'm using the 2nd to last diagram homing routine. It fails right after receiving the assumed index signal. I will try to attach or post the ini and hal files.

PCW,

Thanks for the info. I'm still on the same build, 2 axis lathe with DMM servo drives using your 7i85s 5i25 and field interface boards.
I have been running the drives step/dir for initial configurations to get things going but need to spend more time setting up for closed loop without joint following errors.

To use homing on index you must set up the stepgen in velocity mode and use encoder
feedback to close the position loop

Ah, yes. In open-loop step-dir LinuxCNC isn't even necessarily using the encoder feedback, is it?
You might expect following errors on index reset, though.
