Error in tool_offsetview.py

After the last changes, the error does not appear, but the speed sliders are set to zero.
The only solution I have found so far is to delay the launch of qtdragon. A delay of 1.5 seconds solves the problem.
The only downside is that qtdragon takes 1.5 seconds longer to start, but it's not a big problem.
I think it could be used as a temporary solution.  

Are you using master? There is an ongoing problem with a race condition.

Yes, I use master. This solution using time.sleep(1.5) works very well. Maybe it will be useful to someone until the problem you are reporting on is resolved.  

Yes, now after updating to the latest version it works properly, without the need to delay GUI loading.

There is one more problem in gtdragon, possibly unrelated to the above problem. The 50% and 100% buttons next to the spindle speed slider do not work. I also checked version 2.9.1 running from the ISO installer and the same problem occurs.

I pushed the fix to 2.9 - there is a conflict in master so I can't move it to there yet.

The two action button's property 'joint_number' needs to be set to 0 instead of -1

Hi Chris.

I noticed that when I press the "go to sensor" button in the "offsets" tab
the entire screen is frozen, you can't see the speed or position progress in DRO. (in qtdragon, of course).
I corrected two lines in the handler file in the "btn_goto_sensor_clicked" function and it works fine.
Can you check if this is correct and make corrections if necessary?
Changes in the screenshot.

Yes I think that change is fine - I'll do some more testing though.

After adding five axis to qtdragon , the "go to zero" buttons are not available. Maybe it's a good thing that they are not available, but this functionality would be useful.
Could you add this function to the "ref x,y..." button menu so that it is available for each axis?
Another idea is to convert the fields with axis letters on the left side of DRO into buttons and make room in the drop-down menu for your own macros specific to individual axes.

I don't like the idea of adding it to the reference setting button.
It's unrelated to reference setting and to easy to mistakenly select.

I can't really add the go to zero button back but you could make an INI based macro button for it. would that work for you?

I didn't fix the go to sensor behavior did I - sorry about that.
