Controller fan bogus.

Yes. It's kinda weird. I'll check the wiring again, maybe i wired the tacho instead of pwm. Would that explain the behavior?

Thermistor wonky when N / L are switched

Good work! I have one other idea. I once had problems with induction caused by a 7kV (high frequency) electronic ballast firing up in an i²c line. The solution was shielding the high voltage line with a mesh to PE. The problem was not completely gone, but what solved it was removing the one loop that was still in the wire. Do not coil wires 😄

Controller fan bogus.

It's super strange, as Iam using a 12v parts cooling fan https://www.arctic.de/S4028-15K/ACFAN00264A And this one works fine on the ebb with a 12v enable pin from the Octopus

Controller fan bogus.

@MDFPereira Using: https://www.arctic.de/F14-PWM/ACFAN00218A (Don't remember the exact config, Iam on mobile) But:

[controller_fan controller_fan]
pin: !PE8
cycle_time: 0.01
enable_pin: PD13

[controller_fan controller_fan]
pin: !PE8
cycle_time: 0.01
enable_pin: PD13

This config works now:

[controller_fan controller_fan]
pin: PD13
cycle_time: 0.01

[controller_fan controller_fan]
pin: PD13
cycle_time: 0.01

Cycle time did multiple timings.

Controller fan bogus.

It's always idle, but it has something to do with the fan, not the mosfet. If I connect the fan 3 wire and just use a two wire config it works, if I use a 3 wire config it runs at idle. Strange, but configured as a two wire fan I can run it. EDIT: maybe I'll check if something's not wired correctly, but for now the 4 wire fan is running fine as a two wire fan.

Underextrusion with different nozzles

Ok. So the Generic Ratrig PETG has a flow of 0.93 which for a filament needing about 103 adds up.
