Trying to clean the nozzle, so I’m trying to get the unit up to temperature to remove it. But at power on, my screen show “Err MINTEMP”. I’ve removed the extruder and dismantled it a few times but all the wires seem to be connected properly, all the screws are in place, etc. Anybody have the same problem?
Make sure you have the heater cartridge and thermistor connected properly. They are both two pin connectors. That error is generally due to a disconnected, improperly connected or failed thermistor.
I am currently having this issue with my Taz 6 after a user error ruined one of our toolheads. I’m attempting to install a new toolhead but can’t get anywhere because the screen won’t clear the Err E1 MINTEMP. Anyone have success with this?
I am having the same errors here. It started with a z-axis binding issue. During the process of identifying that problem, the Err E1 Minitemp error came up. Now I can’t do anything either.
I have 2 Taz 6 machines with one being setup for dual extrusion. I was able to swap toolheads but that didn’t stop the error.
Open to any suggestions…
I have a Taz 4. Today the outside temps dropped to freezing and the backroom where it sits showed 6°C on the head, 7°C on the plate when I turned it on. I went to preheat PLA and it showed this Err MINTEMP on the screen. Restarting the printer and the error showed up while doing nothing.
I powered it off for 1min, then on and noticed the error wasn’t there. I held my hand over the extruder for a while and managed to raise it to 11°C, then tried the preheat and it worked. Back up and printing. Maybe it was too cold and something opened up in the heating element. Maybe something opened between the path from the drive circuit to the element. I hope this doesn’t keep happening, or I’ll be posting more finds here.
While this is my easy fix, consider opening up the connector to heating resistor and checking that power is being delivered to the connector by connecting a multimeter (DMM) in ammeter setting. Elements are around 30W, so at 24V this is 1.25A and shouldn’t damage your DMM. I haven’t tried this, and am not 100% sure that the drive circuit will still output power with DMM in the circuit path, but suppose it should.
