enp0s25 is the nic connected directly to the mesa card, wlp2s0 wifi to my home router

no, the green LED stay off.

If i connect to the other card in my lathe and ping it the green LED start to blink

That's analog servo (7I77) setup
if you make a (different name!) pncconf configuration for a 7I76E
it will make a step/dir setup as an example

Sorry I may have explained it weirdly. It will only be a 3 axis machine. X is the pipe rolling, y is the fixed are torch holder moving, and z is the torch probing.

the torch will be fastened to fixed arm centered on the pipe. The arm itself will move the fixed torch on the y axis with a stepper motor.

I think the linear move causing the error is actually line 19, the G43 Z15 H7. I'm willing to bet your tool length + the 15 in Z is pushing you out of your envelope.

are you compiling with release or debug? idk which one but people report trouble with one

This is what my hal shows for one of my axis servos, should be stp/dir. Does this look like a step/dir or analog code.

You should be aware that Linuxcnc is limited to 3 axis look ahead. I’m not sure what that looks like for you, sounds like maybe you’re going to lock out the X axis or the design has it centered over the chuck permanently. But if you’re planning to have XYZA, then know that motion may be jerky (running similar to 3+1), and will not be coordinated with the smooth transitions you’re probably used to seeing out of a 4/5 axis plasma cutter. This will probably be problematic for cut quality.

Of course do your own simulation/testing but wanted you to be aware of the limitations software side.

Pipe:
-up to 4 feet but generally no longer than 1 foot
-up to 10” possibly
-2 roller supports bearing the weight of the pipe

The torch will move on the Y axis and the Z axis. The pipe will rotate on the X axis

What length pipe?
What diameter pipe?
Moving torch or moving pipe?

I’m going to build a pipe cutting plasma. To spin the pipe it will be in a lathe chuck. What kind of motor should I use to spin the lathe chuck? The pipe will be very well supported as well as the chuck. So it won’t be too heavy on the chuck itself.

I'm concerned that a stepped motor might not provide enough strength, but I need something I can control precisely.

i think you are little bit wrong because of mapping... mapping is used to setup communication canal to shape which you need...

you can use legacy or mdp but there will be different temps for your program.. if you will use MDP, my profibus component will not work probably... I had to check them...  but for setup purposes of communication start it is OK

but all of them will need SDOs which tells the slave how to communicate with its master ...

It sounds like you're experiencing intermittent motor position errors, which can often happen with stepper motor setups due to following errors or configuration tuning.
