I found maybe an answer to the indexing problem I am having

These lines are in the m5i20_motion.hal file:

# Connect index enables to motion controller, for homing.
net Xindex-enable m5i20.0.enc-00-index-enable <=> axis.0.index-enable
net Yindex-enable m5i20.0.enc-01-index-enable <=> axis.1.index-enable
net Zindex-enable m5i20.0.enc-02-index-enable <=> axis.2.index-enable

I didnt find something like this in the hm2 files
Can I add this to the servo file and make the hm2 changes


I also changed this line for each axis:

setp hm2_[HOSTMOT2](BOARD).0.pwmgen.00.scale 1.0

To this:

setp hm2_[HOSTMOT2](BOARD).0.pwmgen.00.scale [AXIS_0]OUTPUT_SCALE


To use .ini file settings

Later
