error: stopped - heater error

Recommended Posts

Posted · error: stopped - heater error

so im getting this error sometimes on my UM2, I'd say it happens once a day with around 12 hours of printing a day on the machine. but it stops the machine when it happens. is it just a loose connection? i get the exact same error but with the heated bed as well sometimes.

heater error (as opposed to error stopped - temp sensor)

You get an error if the heater can't move a certain amount in a certain time while driving full power (when it is close to goal temp it typically runs well below full power):



14.09 - does not have the feature

14.12 oct 16, 2014 - feature introduced. 20C in 20 Seconds

14.12.1 dec 15, 2014 - from 20C to 10C (still in 20 seconds)

15.01 jan 14, 2015 - from 20 secs to 30 secs (now 10C in 30 seconds)

It's not a loose connection. Or if it *is* it's a loose connection to the nozzle heater.

Usually it's just a wimpy heater. UM2 used to ship with 25W heater and there was heavy variation so some heaters were only 20 or 22W. Now they all ship with 35W. What country are you in Lance? Please update your profile. You can get cheap but excellent quality heaters from my store if you are in USA (thegr5store.com) or from 3dsolex.com.

Sometimes the cause is too much wind/fan blowing on the nozzle. Sometimes it's because you switched to an Olsson block without switching heaters and now the fan shroud is touching the Olsson block where it's hard to see. If so try raising the nozzle by tightening the round nut - more info about there here:
