Webcam Goes Offline, Crowsnest Restart Crashes RatOS
I have run into an issue. The USB webcam I use (Logitech C270) will spontaneously stop displaying images after a while. I am not sure when the threshold of time is, but usually after some time it just goes out. This is the first issue.
To fix this, restarting RatOS always works. However, recently I have been experimenting with restarting Crowsnest. 2 out of 3 times i have restarted Crowsnest using the restart icon in the power menu, the whole RatOS goes down: the web UI stops working and I can not ping or ssh into the device. On the Pi, the green activity light stays unlit.
The 1 time I restarted Crowsnest and it worked was during the print… not sure if that was luck or what.
Anyways I am not sure what caused the whole OS to crash. Both times there was a crash, it was directly linked to restarting Crowsnest from the webUI.

Lead Screw Screeching (Vcore4 IDEX)
Has anybody run into an issue where the Z1 lead screw (the rear one) has some random screeching/squeaking. It happens sometimes, especially on fast Z moves (like during z tilt calibration). I am able to isolate it to that lead screw because if I put my hand on it and give it a little pull towards the front of the machine while it is screeching, the sound goes away. I put some light sewing machine oil on the lead screw which seemed to fix the issue, but I was under the impression that the POM lead screw nut shouldnt need lubrication. Also after a few days the sound seems to have returned...

VCore4 IDEX Belt Tensioning - Should Mount Hybrid?
I'm working on going through the IDEX commissioning guide and seem to have everything complete. I am now looping back around to perform the standard commissioning guide. In what order should I do the tensioning? It mentions tuning the CoreXY belts first, and then adding and tuning the hybrid belts. However, during the IDEX commissioning guide, one issue I ran into was that the z-tilt cal did not work. Based on reading a couple of threads, the problem was that the hybrid belts need to be mounted for the IDEX machine to work properly for the commissioning, so I mounted the hybrid belts.
Now that im coming back to belt tuning, am I supposed to remove the hybrid belts and perform the tuning, even though I have the IDEX build, and then reattach the hybrid belts and continue tuning? If so, does this change any work I've done up to this point on the IDEX commissioning steps?
