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

In axis?

Sorry, I didn't understand the translation well, I don't speak English, in this case the remora doesn't support high pulse frequencies due to the limited hardware, does the ec 500 and ec300 have an input for high pulse frequency encoders? Or does it only allow you to make an extension module for the encoder? If so, what would this expansion module be like? Is there anything ready? and how would you add it? Sorry for the number of questions, I'm very interested in this project

It is supported, but refer to Murphys post, the limitation is in the board hardware.

My problem is now that if I jog with my keyboard and after i dont press anything sometimes the motors still do 1 or 2 steps. And i cant figure out why. Maybe someone has the same motion controller with linuxcnc or could help me?Thank you

It is related to the motor tuning setting in Remora/Linuxcnc

If I understand the question correctly, you are probably maxing out the steprate.

just ask your questions in the RP2040 thread. its easier to keep track and you will get better responses

Motors aside, the best supported one right now is probably the BTT Octopus 446/429

I don't remember on the Okuma, but the normal setup is a curvic coupling to align the turret. Look at the link for a little more info.

Had the same issue, so it was easier to resolder the pins, but still did not work.
Had no time to test anymore, it is sitting on my desk here for quite some time, but i think i might give it a go these days.
Did you get any further?
