I took some time out to modify the spindle motor windings - I'm
converting it from 415V to 230V. Anyway I got the axes working by
turning all of the enables on. I now have motion and yikes, it's fast!
I'm only running 10m/min and the machine is rated for 15. With a Y
travel of only 0.5m it doesn't take long to get from one end to the other.
Thanks for your help.
Oh, by the way with 7i80hd_16_svss6_8 a couple of my outputs would pulse
on for a fraction of a second as LinuxCNC started up. I think it was 51
and 53. My outputs are active high with the 7i80 resistors set to pull
down. It's no big deal and 7i80hd_16_sv12_2x7i48 doesn't do it.

I'm setting the pwm value in the range -1 to +1 with scale set to 1.

Hmm, can't duplicate that here, just tested and PWM / analog
out works on both 7i80hd_16_svss6_8 and 7i80hd_16_sv12_2x7i48.bit
(using a basic hal file with PID setup and
looking at analog out on a meter while turning encoder)
Here are my test hal/ini files:
