Halp! Max v2 won't heat, shows "DEF" for temp

Post by benjaminhill »

I just cleaned old glue off the print bed, but I thought I had been gentle. Now when I start it up it shows:

NOZ: def . BED: def
Error:Printer set into dry run mode until restart!
FW Version: 0.92.2
Automatic Heater Shutdown in Xm XX

Anything I can do to diagnose what is up?
Some other threads mentioned it might be a blown mofset, or a misbehaving wire... not sure how to tell.

Check to make sure you didn't accidentally damage the thermistor on the bed. That would cause the "def" reading. Note that either one of the thermistors in the nozzle or the bed going bad will cause /both/ displays to show "def".

Mine did that turns out I had a bad connection I ended up upgrading my connection to a quick connector. Took me forever to figure this out. Hope this helps

Those JST connectors are pretty handy. :)
