This drama started several weeks ago now. The filament ran out mid-print and silly me didn’t have the runout sensor turned on. I had thought the nozzle was clogged very badly because I couldn’t get the remaining filament out with cleaning filament or a needle.
I happened to have another entire extruder as back up. It’s a sprite extruder. After I switched it out, I started getting the temperature error.
Over the last week, here is what I have tried:
- Old sprite extruder
- New sprite extruder
- Old sprite extruder with the hot end from the new one.
- Purchase brand new hot end, and tried in old extruder.
- New hot end in the new extruder
- Purchased a new Hot End Adapter Board. Put it on the Old Extruder with the brand new hot end.
- New adapter board on New Extruder
- Checked and rechecked ALL connections and wires multiple times in each step
- Went back to the Old Extruder and the Old adapter Board
So I have 2 adapter boards, 2 extruders and 3 hot ends.
When everything is plugged in, the extruder reads anywhere between 25-28C. Sometimes when trying to heat it up the temperature will rise and either start to fall or hold steady. The highest I have gotten the temperature to is 60C. Other times it won’t heat up at all.
I’ve had this printer about 2 years, so it’s well out of warranty.
Since I originally posted in other forums, I have downloaded pronterface and attempted to tune the PID. I got the AB Temp Error when it started to run the first cycle.
Where do I go from here in troubleshooting? My guess at this point is the cables going to the extruder, the connection of the extruder to the motherboard, or the motherboard itself.
