Firmware SHUTDOWN: MCU fried?
Hello everyone,
After a few weeks I booted my VC3.1 again and now it crashes when I try anything (homing, heating up, etc.). Also, the 4028 fan no longer starts at 100% when booting up, which it used to do.
I have had an Octopus 1.1 installed since October 2021 and never had such problems. Could it be that the MCU is defective? How should I proceed with troubleshooting?...

Idex upgrade, "ADC out of range" - is there something wrong with my Rapido?
Hi, not sure if correct section to ask this, but here goes (please be kind on me for not finding anything by searching and using wrong names on stuff, I'm trying my best as a noob :-P).
I got my hybrid to IDEX kit from Rat Rig and have a problem with "ADC out of range" on the new Rapido.
I noticed that the new one is different from my old one, but not sure if this is a fault or a design change. ...
Solution:
Silly me actually managed to switch the wires on the hotend (thermistor and heating element).
I belive myself lucky not to break anything, after I got it sorted everything works fine....
V-Core 3.1 PT1000 ADC out of range (toolboard fault, unknown cause)
I just finished a rather large print. When I was taking it off the bed, the extruder thermistor stopped working and showing the temperature is -255 degrees. I replaced the thermistor with another same PT1000, but it is still showing the same readings. After some investigation, I found the following readings were possible, but non within range:
PT1000 connected: -255 degrees
No thermistor connected: 878 degrees
104NT-4 connected: -252 degrees...
