Which Preferences?
On Qtplasmac I only find settings etc.
Or am I missing something?

Screenshots of Parameters and Settings.
Hope this is what you are looking for.
If I misunderstood you let me know.

Upload your ini file please.
If the light is blinking faster, the THCAD is working. I would say you have not properly configured your encoder.
FInd the encoder velocity pin for your mesa card in halshow and if it is 0, thats the issue

The Hal file you posted earlier has no external input signals like arc ok or float switch.
If you have run pncconf on more than one occasion then the parameters for the thcad will have been put in a separate file in the config directory so it doesn't overwrite the custom.hal file.

Yes I have not configured things that are not connected.
At the moment I am only build ing the controlbox.
The room where I will put the plasma table is not yet finished.
What is that separate file called?
And what are the implications of running pncconfig multiple times?

It is called "qtplasmac.prefs.new_value"
The two values in there need to be used for Voltage Scale and Voltage Offset in the PARAMETERS tab.
If you have no manual edits in the main .hal or .ini files then you can use PnCconf as much as you like, these two files will be overwritten.
It will not overwrite custom.hal or custom_postgui.hal so it is best to keep your customisations in either of those.
It also won't overwrite qtplasmac.prefs if it exists, that is why qtplasmac.prefs.new_value is created.

I just did an experiment
I changed the jumpers to F/32
And also the settings in pncconf
Now it just shows random numbers.
Just seems to be counting until it starts from zero again.
If I check it in hal meter the numbers jump between negative and positive numbers.
Is the counter supposed to reset so you get a frequency?

I suspect you are probably missing this from your hal file
Your are in the right place but its encoder.00.velocity you need to be watching on the watch tab.
# --- 7i76e ENCODER SETUP ---
setp hm2_7i76e.0.encoder.00.scale -1
setp hm2_7i76e.0.encoder.00.counter-mode 1Your are in the right place but its encoder.00.velocity you need to be watching on the watch tab.
