Aha! For my next try, then
loadrt hm2_pci config="num_encoders=2 num_pwmgens=0 num_stepgens=4"
I am trying to use a mix-n-match of stuff that needs a base thread, by
using the software pwmgen module and importing all my logic from the pure
software hal file.
But I am stuck at the moment by this:
Starting LinuxCNC...
my_LinuxCNC_machine.hal:187: Pin 'motion.spindle-speed-out-rps-abs' does
not exist
Shutting down and cleaning up LinuxCNC...
Running HAL shutdown script
Cleanup done
LinuxCNC terminated with an error. You can find more information in the
log:
/home/gene/linuxcnc_debug.txt
and
/home/gene/linuxcnc_print.txt
as well as in the output of the shell command 'dmesg' and in the terminal
So I think I'm going to have to import a lot more more of my old, working
software config, which will generate that missing signal, much of which
works from base-thread.
But I got side tracked & went back to a somewhat working software setup,
moved the encoder lines around to match the 5i25 & made that work, but
when I chucked a digital caliper to check Z scale I found it off about 2%,
fooled around & fixed that, then did the same for X. The x screw is
supposed to be a 2.5mm pitch, but I have to use a larger value to make the
movements measure correctly. I should hang a pointer on the backshaft,
put a dial on the toolpost, and turn it exactly 10 turns to see how far it
actually moves.
In re the above, I guess next is getting the home switches to be
recognized. Lots of other things I can't test till it will home itself.

I miss-typed, I think the stepgens I can use, and the first 2 on each
socket are already on the correct pins.
So I am getting there, the above line for my hal file will facilitate
things considerably. But its about 90F in the shop already, and I'm
leaving salty puddles as I move about. :(
Thanks for that hint, I'll do some more hal carving later as it cools.
