Fully restarted after "START_PRINT"
Hi, I have a v-core 3.1 300mm with the standard kit configuration (no mods).
Recently, something weird happened.
I started a print; the probing and both heatings were fine.
But after heating to printing temp, RatOS fully restarted without any errors. The print log also shows nothing.
I can't figure out what exactly caused the restart.
Has anyone encountered similar issues?
Many thanks!

upload your klipper log please
MCU overheated?
Thank you for helping! I’m away from my printer right now. I’ll attempt to regenerate the issue later today
Thank you for helping! Both RPi and Octopus are properly cooled, and normally the MCU overheat will show up a notification after restarting but it’s not the case…
Please find the attached file the klippy log
yeah all I see are a bunch of
null characters before the restart. I would ask on the klipper discord what that means as I have never seen that beforeI appreciate your help
I couldn't figure out what caused this issue as my minion and another V-core never had this issue
I have removed the post at #ratos-support.
Sorry for causing a mess.
I ran the following manually
START_PRINT EXTRUDER_TEMP=205 BED_TEMP=60
The issue remains,
1. [working] heating to bed 60ºC, extruder 150ºC
2. [working] Mesh bed probing
3. [crash and restarted] Heating extruder to 205ºCi would assume an electrical problem
Yeah, if you can heat the extruder but not past a certain point, that suggests mechanical/electrical. Check the heater wires for shorts
and try isolating it, try heating just the extruder alone and see if that triggers it.
Aside from that do you have a UPS you can try running the printer behind? Or possibly something like a kill-a-watt that will show you the printer's power draw?
@miklschmidt @TheTik @Jamin Collins [v-core 3.1 400mm] Thank you guys, I’ll check the wiring today~
I did this and it shows that everything suddenly dropped at around 5:10.
When monitoring the power draw, what should I look for?
How high the draw gets, if there are any spikes. I'm wondering if the source can handle both the extruder and need heating at the same time. It shouldn't be too bad on a 300mm build, but depends on your circuit. I know a 400mm can come close to a US 15a circuit when everything is active at the same time.
