rcpwmgen kann variable pwm Frequenz:

Oder stepgen mit step_type 2. Damit bekommst du ein 50% Rechtecksignal

Ok, this is getting weird ... Yesterday i mounted the mesa card from the lathe into the mill, all worked fine... made parts for like 3+ hours .. Today i power up the mill again and the second mesa card network is also no longer working I dont understand, there was zero change to the electronics, since decenmber last year or sometime around.. (added 3d-probe)
The only power coming to the mesa card is 5v from a step down converter (24v->5v) which goes into the vc+/gnd and +5 to the input common.. all outputs go to a relay board. China spindle to pwm 0-10v . Xyz-axis Stepper drivers are on a seperate 48v psu, A-axis Stepper is on the 24v psu

This setup was working for ~1 year... Is there any chance some voltage spike (iam no electronics guy ) could kill only the ethernet ?

I got the charge pump working. I'm still having trouble with the axes.  The led on each of the direction pins on the C11G board lights momentarily when I let off of the jog button. It is brighter in negative than positive for some reason. Pins 1, 14, 16 and 17 are all on constant with the charge pump. (Which I think is fine. nothing connected to those terminals)
I used pncconf wizard to generate the files. The only thing I did to them was comment out lines 22 and 23 to make it not crash. I tried to match up all of the parameters from the previous ini and hal file in the wizard.

Thanks again!

Just contacted them...Thanks 

LXQt is most likely going to be pulled out in the next release as I'm currently having major problems with it. XFCE 4.20 pre-release is actually quite stable though so that's a no-brainer

edit: LXQt problem is fixed for now, will be included in the image.

Analog control drives need some tuning also (to match the load inertia)
This is basically true of all servo drives (though of course some have much
better tuning software or even good autotune capability)

I never used steperonline, but from what i read here, they are always high impedance types, hence me not using them.
Programing wise, it is a 2 axis machine with the automated 3'rd axis, uses Inkscape in 2D to produce gcode.

Did you try pinning the Ethernet IRQ?

As a test you can run this script:

 

chmod +x pinirq.txt then:

sudo ./pinirq.txt enp2s0

And then retry LinuxCNC or the ping test

LinuxCNC is the  (real time)  motion controller that takes gcode or manual commands
an converts them to constrained (velocity, acceleration. position) per joint motion data.
LinuxCNC also gets real time feedback from motion hardware to allow for spindle synchronized
motion for things like threading and rigid tapping.

 
How this data is conveyed to/from motion hardware depends on the actual motion hardware
(analog,step/dir,EtherCAT, modbus,pwm, quad encoder, absolute encoder, resolver etc etc)

Sounds like you want something more like Mach, that buffers motion commands in an external controller
 

Okay I will do that, Thank you! How does this sound?

Would you be able to give me any more information on the pipe cutter? Programming wise, design wise, issues, and all? Please, and thank you.

Yes and no...LOL.

For decades now, my servo drives are configured for torque commands, aka "transconductance"
I develop my own motion controllers that handle PID VFF, AFF, dual-loop feedback, etc., etc.
My latest is using the $10 RPi Pico. Using the PIO state machines, I decode the quadrature with zero impact on the two MCU cores.
Ideally, I'd like LinuxCNC to be the G-Code processor, etc. and take care of the time critical stuff in the Picos.

the command return to me :

That is all good as explained (i tried) above.

This makes no sense as LinuxCNC is a Motion Controller that runs inside an OS, Linux in this case.
I think i might be on the right track as to what you are looking for, but first some stuff to get out of the way
-you have drives with PID loop in them, they are not motion controllers
-motion controller in this context implies opening gcode, parsing it, planing the trajectory for the axis/joints, sending understandable signals to drives/outside world.
-
You can use separate parts of LinuxCNC on their own, mostly, so you can probably use the gcode parser and trajectory planner, but you would also need the sending signals to drives part, so......
any closer?

Yeah I understand this but I want to use my own controllers and my own PID, etc. 

I don't want to rely on an OS for the motion control. Is this even an option with LinuxCNC?

So looks like the DKMS driver (I think the default driver with latency issues "8169")

So not sure whats going on.

What does your kernel command line look like?

cat /proc/cmdline
