It worked, i forgot the handler in the /share/ path the Terminallog showed it wanted to load it. After deleting it started with the Button and i can Open the Pop-up too. Thank you very much for your Help and stamina with me

If you run linuxcnc from a terminal then there should be more information on that error.

it's not enough for me to track it down

This is interresting with your files i still get the error message:

AttributeError: 'MainPage' object has no attribute 'PREFS_'

Ok I edited your handler file - I should have explained how to combine the code.
I didn't remove your popup code but it's not used. 
I used your modified qtdragon_hd.ui file
I made a sample vacuum panel based as a mainwindow with just an LED in it.

I confirmed this works on my system

At the moment, whether or not "sserial_port_0=0xxxxxxx" is added to the hm2_eth line, all 7i42TA pins behave as GPIO - they can be set/cleared in halshow.

This is expected behaviour: if a sserial device is not found on a particular channel, its I/O pins revert to GPIO

I would be grateful if you could send the firmware for that card including: 6x analogue servo, 6x encoder, 2x pktuart and 2x sserial modules, for 7i80HD-25, 7i48, 7i52 combination.

I'll try and get to this sometime today or tomorrow.

OK this worked and we got rid of the type error, if i start i now i get a attribute error: object has no attribute 'PREFS_' , i hope you dont get frustraded with me its all very new for me. I really appreciate your work with me. And it means a lot.

please build your panel as a main window instead of a dialog

No idea how this happend i will post and check it this time

The ui files are 0 kb for some reason

I'm not expert too, I've just been experimenting with AI and looking at the halscope, trying to wrap my head around things in general, it helps to just chat about these things, even just to make sure I'm not persuing a weird irrational tangent, and I'm actually making sense not just to myself lol. YangYang has the math down, he is the main arbitror, nothing goes to master without his stamp of approval, and he checks on what the AI comes up with, and so far nothing really sticks, only what he write himself works best. I've found something with the arcs, I want him to take a look, and I think we maybe possibly be able to do similar tricks with Béziers, but I don't want to keep your hopes up, I think it is possible that, the fact that Béziers change curvature, may not fit with the current tp lokahead/blending architecture, but maybe... maybe I am wrong.

Yeah for sure these are the files, the error code is already above.

You MUST set the 7I97 PWMgens offset mode to true or runaways are guaranteed.
 

Yep, that fixed everything! Thanks a million! 

For those who run into this in the future, I needed to add to each axis definition in the .hal:

Where "xx" = joint number. 

Now the machine is stable and jogging smooth and silently. Beauty. 

please post your ui and handler file and the exact error message please.

Ive integrated your handler File now into the Main handler. Problem is that the Error Code is exactly the Same as before.
