M112 Emergency Stop

Hi there.

I am not sure if its related to this

 

https://forum.prusa3d.com/forum/original-prusa-i3-mk3s-mk3-hardware-firmware-and-software-help/error-min-bed-temp/

 

But today I cam downstairs to find my print had an emergency stop M112 stop.

There was nothing else, is there a way for me to understand why it did this? logs or what ever?

As far as I am aware the temperature last night was circa 14 may have got lower but this printer is in a box and had already been running for hours so would it still be expected to fail even though its already hot?

Any advice gratefully received, I was 24 hours into this print. Sigh.

Check your thermistor wiring: Anything damaged?

If this happens while printing, mostb of the time the connection to the hotend thermistor is bad.

This not an uncommon error on the MK3S.  It was common under the last version of the Firmware.  Check to make sure you are under the most recent version.  I still get the error once a month but it is not weekly like before and I have 8 of these bad boys.

Hi is there like support I can speak with, I can only assume its hardware.

 

I moved it into my office and have watched it like a hawk. On a print tonight in a nice warm office it just suddenly stopped saying 'restart, min bed temp fixed'

I have checked the wires they look good to me.
