Practically all modern network cards have polarity autonegotiation
Auto-MDIX. I think this is at hardware level.

Correct my current setup is Mesa 5i25, 7i76, THCAD and Gecko 203v's with

Well that was interesting.
I created a, modest, screw compensation file and I'm most impressed by
the effect.
I added a limit switch for X home in the middle of the table (to get
some repeatability of the axis screw position) and did:

One more question on the way to a solution. I've found
references on how to pass hal signals to ngc programs,
but not vice versa. If I want to use a parameter from my
ngc program in my hal logic, how do I pass it? Will I need
to hijack something like spindle speed or can I pass arbitrary
paramet
I am setting up a dispensing application, and would like
to drive a stepgen at a rate proportional to the current
vector velocity. I recall reading some discussion of this
kind of application a year or two ago, but can't find it in
the archives. Basically, I have a little Haydon linear

Yes, that is exactly what I was about to suggest when

I take it that you used the Mesa THCAD with your current THC comp?

I have a few computers with a live OS (Porteus, great little distro). I've
tried to setup up the simulator but even though it looks to me that I have
the missing libs installed they are still missing. I want to run a few of
these with LinuxCNC for educational and testing purpose.
Has someone tried
Yes, I built my own plasma table.
