It is single-ended (I had assumed a change in state was all that was
required). How do I invert the signal at HAL level. Would you expand a
little on why that may defeat the logic in the mesa board please?
Thanks

Your index pulse has the wrong polarity. Note it is sending

I'm very new to EMC2 myself and am struggling to get the index for the
spindle working correctly. I noticed the m5i20 motion hal file has the
index setup commented out. I tried un-commenting them last night and I
get the same error as when I tried to enable the index on my spindle. I
think t
I just got the pluto hooked up to a small servo to play with. Cool little
board btw - nice work on the firmware jepler. I hacked the lathe_pluto config
as a starting point and did a quick ziegler-nichols tuning session (increase P
until oscolates - measure period - calculate P, I and D) That
Why doesn't homing complete at the index pulse shown here:

You should run memtest. The cd you installed Ubuntu with will have
memtest as one of the options. You may have installed memory but it
may not be functioning correctly. Memtest will tell you if the memory
has problems. This my hang the install.

Absolutely. One small step at a time, though.
Or maybe have an environment variable: GCODE_PATH and search a set of places
in order. Add to the GCODE_PATH with something from the .ini file.
