Could you give me a step by step? I don't really understand what I should do

the dkms drivers require linux-headers for your kernel version. I don't think its installed.
The dkms system compiles the driver for kernels if they are changed or upgraded and the headers are required

Hello,

is the any way to change the network card driver from default generic to my hardware native e1000e when I install ethercat stuff from responsitories please? 

thanks regards

I think only the generic driver is supported in the deb install. If you build Ethercat master from sources I think you can build the Intel driver which will give better performance. Check the docs which outlines the build process. Its pretty easy.
etherlab.org/en_GB/ethercat

Should do just fine.
Beware those do not have air pressure sensor so they do start with no air, and that will ruin the torch isolation in a jiffy.
Ask me how i know that?
My dad pulled the air hose on the big compressor so i wasted a brand new torch. It still works but fails to start often.

Also, don't forget spikes on piercing will be much higher than cutting. Even at 40 amps, it is enough to exceed 300 volts when cut volts is around 120 volts. Not sure how much higher because that was the max voltage my thcad was calibrated to. Also when crossing a void, when a slug drops when cutting a hole, running off a sheet when severing all cause huge peaks. A thcad used for ohmic sensing Is exposed to the full torch voltageeven if calibrated fro 24volt full scale.

A1 goes to AOUT (or spindle out) on Mesa.
0V common goes to spindle-.

Yes, that is the easiest (and probably the best) solution.
Edit:
Make configs for each tube diameter and set the scaling so they do a full rotation for each diameter.

I thought an MPG can also be used, with "normal inputs".

Similar to spindles: Some refer to the continuous power output for production and some state the "spindle goes up in flames" power.

Motor torque can be stall torque, holding torque or continuous torque at a certain rpm. 

 

Maybe this:

i bought a Plasma cutter a while back and had plans to do a cnc table for this but  i wanted a machine torch rather than the hand torch that was included with the unit. I just happened to see a deal on Amazon that was pretty good so i jumped on it part of the problem with the hand torch was it being an odd ball and consumables being hard to find and rather expensive. but this deal solved that issue. $80 for the straight torch was hard to pass up looks like a 4' x 3' build in the works and i think i might try a down draft table. i was looking around and was curious if i could use an old blower from a furnace for this since i have one laying around. 

     

Oh, apologies I was looking at the wrong move.

Maybe try this:

Not sure. You have another subroutine call 'retract_pocket' after the G91 move in question. Maybe try stopping the read ahead before it ingests that and enter a debug line to make sure the Z and F word are what you expect them to be:

This are terminal connections on VFD: 

 
 

So proper solution would be to take +10V Reference output on VFD, connect it to SPINDLE+ on 7i78 and Local voltage speed reference input (A1) on VFD and connect it with SPINDLE- on 7i78?
Any need to connect also 0V COMMON from VFD?
 

Ohmic sensing has been working reliably for the past few days. I would not want to be without it. Makes probing so much faster and more reliable.

So my fifth stepper motor driver arrived and I will soon take the plunge to add a rotational axis.

So I read linuxcnc can only handle 3 axis trajectory planning.

But I need a fourth axis to place the torch above the center of the pipe.
I guess this can be done during homing.

Should I make a new configuration with the rotation axis being the X axis. Change the current X axis to the A axis in order to move the torch to the center of the rotation table?

Its more Hbot than corexy, but its more of a T bot, or t_t bot which forms an H shape
