Entombing that mess with a squirt of hot melt glue
-
As an added benefit, when the bulb lights up you know the Extruder Motor has died!
-
A gas-tight joint is a happy joint.
-
And now for the long-awaited and much anticipated thermal coefficients for the insulated and greased Thermal Core:
-
A cheap mechanical switch works just fine!
-
In an ideal situation, the coefficient wouldn’t change
-
Now we can compute the temperature differences between interesting locations on the Thermal Core.
-
This would be significantly easier if I had a thermocouple with a known-good calibration, but I don’t.
