EC11

Post by 7thcitizen » 10 Jul 2020, 15:03

Shortly after manually extruding filament on Extruder 1 successfully, E1 temp is showing -15*C when trying to manually extrude. Extruder 2 reaches temp without issue. Ran self check wizard and immediately received the error EC11. Checked connections as instructed in the operators manual, ensured everything is connected properly, rebooted device and still receive error EC11.

Apologies for asking any silly questions/repeating what you said, just want to make sure that I understood everything correctly:

So, since you say you performed a manual extrusion on E1 then I assume you passed the initial self test the printer performs and when you manually extruded from E1 the printer detected the hotend getting up to temp.
If that’s the case I would probably recommend a few things & if not you can reply as such (I’m pretty new to all this, but the following seems logical):

1. In case you haven’t tried using the printer again since the error I would give it another go - I had an issue with the printer getting confused due to heat from the other extruder. Just needed to wait a bit and restart. This probably isn’t the case, but worth a shot.
2. When putting my printer together I noticed that one of the thermocouples wasn’t held in place very well. This could possibly be the same with yours - id double check to make sure the sensor is properly in the hot end.
3. Assuming the first two easy answers don’t work out the best bet would be to get a multimeter out and check the voltage being created by both temp sensors. See if they are the same at room temp (and can try heating them up too).
Another method could be to reverse the heater wiring and temp sensor wiring between the two extruders and see if the problem switches to E2. If it stays on E1 then the heater/sensor are probably fine.

Hope this helps

Thanks for the great reply! Turns out one of the temp sensors was broken and once replaced it’s working well. I also had a thermocouple that was loose, made me think I was losing my mind when I was adjust nozzle height and leveling. As my luck usually goes, I believe I broke the temp sensor when I was tightening the thermocouple.
