  'm running Sherline CNC with their PC with I believe Ubuntu. What can I do here? I'm not familiar with Linux but there was no sign that something bad with SSD before. Ive got such experience with dying SSD on MacBook but it showed a clear error in the begging so I could copy the file system and remount it on a new SSD. I've got install CD but can't figure out what's wrong

No, not easily, but you can use CAM software to do that and use it with QtPlasmaC.
There was talk of adding 4th axis for cutting square tube, i do not recall it was actually done.
In general, that is not something LinuxCNC should do, it is CAM's responsibility to output correct gcode for the machine, LinuxCNC is for running that gcode on the actual machine.
Even with CAM it is quite complicated to do 4th and 5th axis as that changes actively tool center point on all directions, so it will not be just click to export gcode.
Sorry i can not help more.

I forgot to mention, i do not like RPI for machine control, at all, but i do understand why others like it and use it, but the thing i can not justify is the price, for the same price you can get a used Lenovo laptop with touch screen even, but i can not advise getting laptops as they might end up not having good latency. I have probably 6 or 7 laptops like that in daily use without issues, but i am sure some might not be good.

I set some sdo values last night and the shaking is gone. The servo motors make a bit of a whine noise, so I might need to turn the gains down a bit more.

I’ll post all my files later on today.

The stepper motor just works, but the servos need some tuning is my perspective.

Thank you. My motors have encoders, but I don't know if that's enough to avoid needing encoders on the board.

I'm looking for a combination that is easy to install and not too expensive.

Sorry i can not help with Fusion, i use strictly Inkscape for all plasma machines, just use "prepare for plasma" and then export with the tool chosen as plasma.

Yes

Hello.

Thank you. Is that video option better than a Mesa 7i76E + Linux PC?

Bruno, no spamming, if you have something to offer do it on "user exchange" section of the forum, with clear descriptions of what the offer is.
And if you hide the link again, you will get banned.

This is normally considered spam, but it is for motors so might be useful to someone.

Sorry for the late reply, but all you had to do was
sudo apt update
before trying to install.

I would go with Mesa 7i95T as it can do 6 axis with 6 encoders and ethernet, all in one single board.
There are also other combos from Mesa that might end up costing less if you do not need encoders, like 7i96S.

Does the machine have 4th or/and 5th axis?

Can you program QtPlasmaC to make a bevel cut and how to do it.
 

Thanx for all the advices , PCW , Lcvette , Langdons , I already start to rewire the 24 V needed for the pins from a estop controled wiring , this is a good solution .
I will atached the hal files that included the carousel movement.

Actually you can:

setp  hm2_7192.0.encoder.00.index-enable true

As long as hm2_7192.0.encoder.00.index-enable is not connected to
a signal in the hal fiie. It will be set true once at LinuxCNC startup.

The error you have is that you did not comment out the net command connecting
hm2_7192.0.encoder.00.index-enable to the signal x-index-enable:

# ---Indexsignal GMS fuer Referenzpunkt X (NICHT MIT NORMALEM ENDSCHALTER)

net x-pos-fb  <=  hm2_7i92.0.encoder.00.position
net x-vel-fb  <=  hm2_7i92.0.encoder.00.velocity
net x-pos-fb  =>  joint.0.motor-pos-fb
net x-index-enable  joint.0.index-enable  <=>  hm2_7i92.0.encoder.00.index-enable
net x-pos-rawcounts  <=  hm2_7i92.0.encoder.00.rawcounts

But for testing it's better to do this in halshow

Note that while you cannot change hm2_7192.0.encoder.00.index-enable
in halshow (or the hal file) if it's connected to a signal, you can
change the signal ( x-index-enable) in halshow for testing.
