Cut Recovery Not Consistently Triggering

Category: Plasmac

Hello,
I have similiar problem.
I was running latest version of linuxcnc(complete installation from usb drive), and cut recovery function was working correctly.
Because I am in the process of creating localisation for the qtplasmac, I did the RIP install (v2.10-008.054). And now the cut recovery is not working.
The cut recovery window shows up ( when paused or triggered by arc-ok loss), Z goes up, but forward and back buttons are not working. I mean they click "yellow", but axes doesnt move on the contour. directional buttons on the screen are working.

I did two of these RIP installations on different computers, and behaviour is the same.

Even in the qtplasmac-metric simulator it is not working.

M52 P1 is called in the program.
Do you have any idea what can cause this problem? thank you.

Your remedy is working as it should and now i can set correct value, thank You. But I forgotten to tell that linearity of voltage 0-10V is terrible, I used scale for make it "more linear" and that works like a charm. Before on raspberry pi 4 i didn't noticed that strange behavior, it was simple as that to calculate resolution etc, but I also didn't use qtdragon display, when I switched to rpi5 then I noticed those strange things.
Now I bend it little by cheat real max rpm so its almost fit, but I don't like doing things in a slapdash way.
Below table how analog output voltage works for me...
value [RPM] / VFD frequency [Hz] / Uout [V] .
3000 30 0.8
6000 93 2.36
12000 220 5.6
18000 350 8.6
20000 396 9.6
21000 400 9.7
