Engine information panel

He writes a panel for monitoring the temperature of engines.
The fields at the top are editable.
How can I make it save these names in the preferences file to restore the names after restarting the program?
I would also like to add engine RPM.
Is there a simple way to read the rpm from linuxcnc, or do you have to calculate from the feed rate?

This looks like qtvcp not pyqtvcp - or is the added panel pyqtvcp?

Yes, qtvcp. I used the spindle_belts panel as a source.
I have motors built in quite a small space and I want to control their temperature.
I would like to add engine RPM.
How to get engine RPM value?

mentions how to use the main screen's preference file for an embedded panel.
Most stepper/servo components have a velocity pin to connect to.

I wrote the belts panel with a lot of help from Chris.
The final files are here in the development thread:
forum.linuxcnc.org/qtvcp/48061-how-to-ma...n-hd?start=70#270283
It shows how to save and retrieve values from the .ui file.
To change the field names displayed should not be hard. You just need to set the label or name. i don't use this enough to be specific,
And yes I think exception should be except.

Yes, the titles of individual sections with engines already work for me, it saves and reads from the preferences file.
I don't know yet from which pin I can read the engine speed.

I don't think you can get motor RPM. Motor velocity as it is translated to velocity. joint.L.vel-cmd gives you the commanded velocity but that might not reflect actual velocity.
If you really wanted RPM you would need to scale it based on the parameters you entered into stepconf or pncconf.
But motion.current-vel is the only one that gives actual velocity (of all joints).
