Unresolved Continuing issues... MINTEMP TRIGGERED

I've about had it with this printer. Status so far... I had a short in the heated bed wires. Robo3D sent me a new heated bed, and the clip, and eventually a new arduino board when the print still failed. Replaced everything, and still, no go. The log reported some unrealistic temps, and dropped off completely. A new themistor ordered and installed but the same error as below:

<-Error:0
<-: Extruder switched off. MINTEMP triggered !
<-Errorrinter stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting)

I've checked all the connections and replaced what I could, namely a brand new stud type thermistor and the arduino board. The upper board (sorry, not sure the technical term) where the scorch marks from the short is was not replaced so I don't know if that's an issue or not.

From my other readings, it sounds like the printer is not getting a valid reading from the thermistor and it's shutting everything down, but I have anew thermistor installed with all the wiring inspected so I don't know what the issue might be. Any ideas?

 

Thanks, I'll check again this evening.

 

Rechecked everything and everything is connected where they should be. I can't control the printer at all anymore from MatterControl, and with the XXL controller, I can't move the Z-, only Z+. X and Y work in both directions. I'll contact Robo3D help desk.

 

Sorry to bring this thread back, but was there a solution to the issue? I'm having similar issues with the mintemp triggered error and wanted to know what worked for you.

 

I feel like I've gotten this issue a lot when the hotend has a clog/jam which came from me trying to improperly remove the filament so I could change spools. Clear the clog by removing the extruder from your machine (I think it's two screws on the side of the extruder). Then while carefully handling the hotend (Use something to protect yourself and the printer from the heat, I use Teflon covered channel locks with no/very little pressure to hold the heater block. If you see filament sticking out, make sure the hot end is up to temp and gently pull the remaining filament out with a tool that has strong grip such as needle nose pliers. If you can't see any filament and you can't see through the end of the hotend, you have two choices you can disassemble your hotend (Which I honestly don't recommend because its somewhat complicated and I find I always do it wrong and get leaks which make the prints turn out funny,and I suck at it in general) Or while holding the hotend with the Teflon covered channel locks take another piece of filament (8 -12 inches should do) and make sure its as straight as possible and push it into the top of the hot end while holding the heater block off the bed with the channel locks. With enough patience and slight and even pressure (Be gentle when pushing the filament through, you are stronger than you think and the metal is more malleable because its hot ) the remaining filament will extrude and you will be able to pull out your removal piece of filament and the clog should be gone. Then turn the printer off and back on and the message should be gone.
