Very weird stuff going on. First here is my environment:
I have an Ender 3 V2 Running Smith3d Marlin 2.0.x.14 and Octoprint OctoPrint 1.4.2 Python 3.7.3 OctoPi 0.17.0
If I start the printer then boot my octopi raspberry pi and connect (it's automatic) and then try to update mesh under bed visualizer nothing happens unless I home the extruder head first. Not a big deal but thought I should mention.
If in octopi (web interface) I select a preset temperature profile then go to bed visualizer and click on update mesh it gets about halfway through then crashes printer and printer panel freezes. It looks like octopi.local is still up but even if I reboot printer I can't reconnect I have to restart octopi also.
If on the other hand I select temperature profile in octopi let the printer get warm and toasty and then shut off the temperature profile, I can then update mesh under bed visualizer.
Here are some log files. Any help or insight would be appreciated.
