Its a bit tricky to setup a PID speed control with a unipolar analog control
and FWD/REV signals.

I would first try eliminating the feedback by running the spindle open loop
you can do this by setting all PID terms to 0 except FF0 which should be  set to 1.0

If you need feedback (this is rare unless the spindle speed control is very poor)
The structure needs to be like this:

PID command = signed commanded spindle speed in RPM
PID feedback = encoder RPM
PID output --> ABS --> analog out
ABS sign (of PID output) determines the FWD/REV pins

Sorry, I guess the images didn't upload. "hm2_5i24.0.7i83.0.2.analogout0 <= spindle-speed-DAC" reads in forward and reverse. In reverse it shows a reading of 8.25 and stays there, doesn't move when trying to adjust the speed.. In forward it stays around 2.69 with some variation in the next 5 digits. It moves up and down with speed adjustment.

www.welectron.com in Germany has only 7i96S in stock right now
www.eusurplus.com in Portugal has all mentioned above in stock

7I95T looks good. But I couldn't find a cheap German oder european source. There's a German shop that has none in stock. Just contacted them to see when it'll be re-stocked

Will this be a good choice for a hobby machine?

Is the Phoenix the 600x600x600 one with cnc machined parts?
If yes, probably will not be released, i recall they mentioned it was made for a client so they might not approve.
Adding my view here, there are 3D models for Voron with 9 or 10mm wide belts, i built one with those at a 460x460x1200mm size, so no need to wait, just print the gantry and toolhead parts for wide belt and size it up as you see fit.
Resizing a Voron is easy, use their wizard on the website, it spits a complete list of parts with actual sizes.

Post to change the title back to Remora - NVEM / EC300 / EC500.

A 7I95T combines the functions, or a 7I96S+ a 7I85, or 7I85S can do it in two cards

Sure, but I would get rid of the LPT-port requirement and could use any computer, not only this specific one (if broken one day...).

Which Mesa card would be your go-to in 2025?

And is there a card combining outputs (for the stepper drivers) as well as inputs for linear magnetic encoders or would this be a combination of two cards?

When i Look at this lines, there is incremental rapid from Z25 to Z2 and feed move incremental to -10
The moves with G3 are all incremental G91, so a pitch of 1, with lead in and out exactly to Z0
Line 44 switch back to abs G90

Sounds like it did not get an Arc OK signal.  

The criteria is different depending what Mode you are using:

Hi .
I'm trying to output an operation with thread milling but the gcode output for z position is static.

The Z axis stays at 1 mm.
I did discover if you open the machine editor of youre machine and go to Working Style => General and you put Software Transform to YES , the gcode output gives the corect z output:

The problem is there is no more subroutines, the o call does not exist anymore so is M98 , M99.
The post processor is from here: github.com/G-S-E/SolidCAM-postprocessor-for-LinuxCNC
Thanks

Thats what i got so far 

I tried it again without changing anything and the plasmacutter started without firing at startup. Then I loaded the materal and tried to make a cut through 10mm mild steel. The torch fired, but the machine didn't move. And the torch went on and of a few times.
Why does that happen ? And why doesn't the machine move ?

more fun
i think im almost ready to order the atc parts.
