Heater fault when moving Y Axis

kmoore

Hello, I could use some assistance. I am setting up a build using a DUET 3 HC6. I am installing a pellet extruder that is has three heaters with independent K-Style Thermocouples. I have the thermocouples ran to two daughterboards. I was able to get the heaters tuned but now when I move the Y axis my heaters fault and set to 2000 c instead of their actual temp.

I checked the wiring on the thermocouples.
I made sure the continuity is good.
I disabled the Y Axis and moved the extruder by hand to see if it would trigger the heater fault (It did not).
I've checked the wiring of my Y motor, everything is great.

Thank you for your help

below is the link to my config file.

Are you using thermocouple extension wires?
Are they of the right type?
Do the wires run next to any motor wiring?

@phaedrux
I am not. I am currently using 24ga wires. Did not know that thermocouple wires needed to be anything special.

Ill try that next.

Thank you
