You can but often (mostly) the cursor doesn't appear. Just click in the box and type, then you will see the entries. You also need to press Return to confirm the entries (or click an aorrow). This seems to be a typical GladeVCP issue.One minor Point: the value in the material - amps i can only change with the up/down arrows. Its not possible to change the value with direkt entry.

Peter, Yes this could be used to provide dynamic control. See my other post.
This pull request of mine is a large part of this as it provides the arc radius and other key data in real time
github.com/LinuxCNC/linuxcnc/pull/900
I think it would be a separate component that applies this to some yet to be invented algorithm. The centripetal limiting is also a factor but some radii as we calculated were so small it was of little use so it made me wonder if we really had the math right. Solving my maths puzzle would be a great step forward as we could feed that into hole and radius processing.
Why do I think you could probably do that maths in your sleep?

Dynamic current control is a whole different subject which would probably require
infrastructure in PlasmaC. Could this be used to vary the current based velocity
on corners and avoid THC corner lock?

And you need the scaling to be 100 if you want to have 1A steps or scaling of 10 for 10A steps.
That also needs to have the same max_output and maybe something else, can not check right now.

If you set it as a spindle you can set it from gcode, MDI or keyboard b pressing F11 and F12 to lower/raise the current respectively .for me it is advantageous if I can adjust the current setting from the material settings. I don't have to go back to the plasma generator every time to change the power setting on the device. And I can't forget to change the value!! For me it´s not
necessary in real time.

I have now managed to transfer the power to the plasma generator.
The spindle was still missing to switch on permanently with:
postgui.hal:
net run_current plasmac_run.cut-amps-f => hm2_7i76e.0.7i76.0.0.spinout
setp hm2_7i76e.0.7i76.0.0.spinena 1
setp hm2_7i76e.0.7i76.0.0.spinout-maxlim 120
setp hm2_7i76e.0.7i76.0.0.spinout-minlim 0
setp hm2_7i76e.0.7i76.0.0.spinout-scalemax 120
I have set the scaling and the maximum limit to 120 because 12V comes from the plasma generator.
As already mentioned, it is not possible for me to directly assign a value to the setting of the amps in the run tab. I can only jump up and down with the arrows.
Thanks again for your help.

Sorry, i forgot to mention that the problem is with the gmoccapy user Interface.

OK, it seems that Gmoccapy doesn't work correctly if keyboard shortcuts are enabled.
I don't think there is anything I can do about that.

I found out why I couldn't edit any entries (neither nor feed rate, ampere, ect.)
In the settings it is possible to activate or deactivate the keyboard operation in the hardware tab (gmoccapy).
If I activate it then I should be able to use the keyboard, right?
But when activated I cannot set any keyboard entries. If I deactivate it then I can edit the entries. Is that twisted?

I just updated linuxcnc.
Now linuxcnc no longer starts. If I comment out the entry "net run_current plasmac_run.cut-amps-f => hm2_7i76e.0.7i76.0.0.spinout" then linuxcnc works again, but the current value is no longer output (before it was working).

Is it possible you need to update your PlasmaC version to the latest?
if you re-installed LinuxCNC you may have and older version of PlasmaC
