Duet2 reboots at random time

ShOrTy

Hello everyone,
my Duet2 started to reboot at random times.
I thought it would be the board, but i switched it and the problem remains.
Basically i have some faulty peripheral.
Connected to the board i have limit switches, stepper motors, thermistors and resistors...

Well a faulty limit switch would give a false signal nothing more, a faulty thermistor would give false temperature values, a faulty resistor would not heat up ... so basically my question is, could a faulty stepper motor reset the board??

SIam

after the board reboots go to the g-Code console and enter M122 and post this results here
