Visual Mesh Not Rendering

[spimoe]

Hi there,

I'm suddenly encountering an issue where the visual mesh won't render. When I click on the update mesh button, the printer goes through all of the motions, gets the mesh data and outputs it to the terminal, but no visual mesh shows in the box. It's just... empty. Attached is a screenshot of the empty window, and below is the output of the debug log:
[2021-03-04 21:03:30,103] DEBUG: mesh collection started

I did have an issue with my pi and had to power cycle it and then restart OctoPrint to get it out of safe mode, but from what I can tell, everything with OctoPrint is functioning. I also tried uninstalling and reinstalling the plugin, and using different browsers and devices, but nothing has worked.

I appreciate any help and am happy to provide any helpful info.

Realizing it might be hard for a mesh to generate with the values showing as they are, so this isn't a Bed Visualizer issue.

Not necessarily, but if you notice your offsets are extreme. You would need to adjust the options to use relative z offset (will reduce the points down to the lowest being at 0), change the z limits to higher numbers, or use auto,auto for the limits.
