AXIS Preview refresh rate not high enough

Hello,

i want the Preview and GUI to refresh at the highest rate possible (in my case 59.8Hz = approx. 0.0167 seconds)

i have searched but only found CYCLE TIME= under DISPLAY section. i have set that to 0.0167 but it only refreshes at that rate when i move the view in the Preview field, when i dont do anything it refreshes at about 3-4 times slower. How can i change it to refresh constantly at the same rate or better at the refresh rate of the monitor?

thanks

I believe the refresh rate in AXIS is set to 50 ms in it's python code.
That can be slowed by higher priority code of course -typically a fast realtime thread .

Why do you need it updated more often?

I'd be more concerned with running gcode accurately. Forget about "eyecandy" lol

My BBB is supposed to be slow GUI wise but I reckon it's fine. And it cuts well.....and that's the main thing

its just a thing that "triggers" me a little bit and because i will use Mesa Hardware i dont think it is going to be an issue, or is it?

yeah on the BBB it is a limitation because there is no good graphics driver for it, had the experience myself. Mine refreshed the last time when running Gcode at about 1-2 fps, even with "Axis, stop" (dont show toolpath) and only showing DRO

The screen update rate does not affect any of LinuxCNC's critical timing paths.
On a slow machine the display may be almost frozen and the interpreter/real time will still
finish the gcode properly, the real disadvantage of a slow display is its not great as a user interface
since its not rapidly responsive to inputs.
