My first guess would be a damaged I/O pin on the 7I92H (so marginal levels)
BTW, a good way to check for I/O pin damage is to check the input protection
diodes with an Ohmmeters diode check function (positive lead to ground, negative
lead to I/O line)
All lines should show a consistent

Hi everyone,
Been working on my Spindle Control with the adaptor board to allow either PWM
from PP DB25-14 and DB25-16 for Direction. Or for MACH Step on DB25-14 instead
of PWM by simply checking a different box.
I've had the PP version of LinuxCNC also running the step/dir out but it just

All I can say is download it, install it and try it. Its working great

yes I hope I can retrace his work and build one.

The rpi4 seems like it might be a good solution.. (when you absolutely
need a small form factor.)
I have been testing it with the mesa 7i92 - defiantly some growing pains.
(my last problem was timesyncd(default) didn't play well with realtime -
ntpd did)

Linuxcnc get used because it works ... at least well enough to get most

I hope Gene gets something workable out of the Rpi4; that looks promising.
My vision of a new system is something very modular. Small boards
running a microcontroller with some chance of the chip not

I'm a hobbyist and I like the fact that Linuxcnc is an all in "one package".
I don't want to be messing with different modules, Machinekit is going
down that route, maybe it be better for you to have a discussion with
the developers there.
Tormach seem to like the LCNC architecture, so much so
