The SPINENA output is switched on when the Analogue output is enabled,
so there isn't a way to have analogue output and have those terminals
not activated.
I think that the SPINDIR i
I don't think so but I am trying now. I tested the vfd first taking PCWs
advice and just put a pot on the anolog input and buttons to switch between
LI1 and +24 in the vfd for forward rotation.
reverse rotation was just switching between LI2 and +24.
Is it possible to just change the hal a bit an

Can you configure the VFD for "On" and "Direction" rather than "fwd"
and "reverse"?
The 7i76 ou
I can make a video if you guys want me to describing the problem..

ok gene just a update
I have the mesa card connected to the vfd now.
currently the analog signal is working fine I can it being read by the vfd
which is good.
I am having trouble with the control signals though.
I currently have the 7i76 spindle enable pin switching the forward pin on
the vfd

I have a schiender vfd made in France so a proper manual lol.
It's just the Mesa card I'm not sure about lol

Bashrc could be a way, adjusting the path based on the kernel, a string could
be added to the kernel command line and by parsing it through
/proc/somethingicantrememberatm, it’s in the early am here, but I know it exists

Grub will let you choose kernels.
When configuring the linuxcnc build LinuxCNC you can choose the

Parcelmonkey appear to be resellers, ie they have accounts and sell
shipping at somewhere between wholesale and resale rates.
This does mean that they can be a lot cheaper, frequently half the price.

"To avoid this problem, either drive loads that are ground
referred, Use 3.3V as the VCC for VCC referred loads, or use open

Please change that capital U to u,
Also, beef up the a || b || c logic with 'or use'.
