Thermal Runaway error with PETG (silicon sock is on)
I have a CR10S with the full Direct Drive, hotend upgrade for the CR10S (The DDS upgrade kit).. I have set the stepper motor to 4.5 V and running the Bondtech firmware.
When I am printing PETG at 250 degrees or higher, I keep getting a thermal runaway error when the cooling fan is higher than >=50% (I have 50% dialed in after layer 4 in Simplify3D and immediately get the error). The blue silicone sock is on.
Is this normal behaviour? I thought the problem would occur only when the cooling fan is running at 100%?
Is this a worthwhile discussion?
