timer too close
Hi everyone,
My printer was printing a part when it suddenly stopped with the error: "MCU 'mcu' shutdown: Timer too close" on the first or second layer. I then updated all components and restarted the print, and it seemed fine, but then failed about 10 layers into the print instead.
No changes were made from last print i made to this print. I will attempt to reprint the last succesfull print to check if its the slicing, that somehow caused it (but i suspect not, since it was on different layers).
I noticed that print_stall is equal to 1, but I have no clue what that means.

I read that other users had issues with their webcam, causing that very same error. Regarding that, i noticed that no matter what i did, the webcam was greyed out on the dashboard, but worked fine under the webcam tab. This is not the first time I've experienced the greyed out webcam on the dashboard, but usually a reload or two fixes it.
I proceeded to restart the RPI, and afterwards the webcam was available on the dashboard as well.
I then started the same print again, and this time it completed without any issues.
I'll have to print some more files to verify that it indeed works normally again, but for now, it seems that a simple restart was enough to take care of the issue🤞
Unfortunaly, I had another error code the very next print 😦
The new error being: MCU 'mcu' shutdown: Missed scheduling of next digital out event
At least this gives another hint as to what is wrong. Since both the timer too close and missed scheduling error might be communication, it could very well just be a bad cable. I will attempt replacing the cable between the RPI and the octopus, to see if that fixes it.
Seems to print fine now, after replacing usb to usb-c cable. I will keep printing to test if this was truly the issue.
Oh yeah, and i'm keeping my monolog going here, in case someone has the same symptoms, they can read my journey with the issue 🙂
