Help with apparently too hot printing
-
@jens55 some fans does not like being pwm'd. Try changing the switching frequency of that fan when you declare it in config.g .

@mikes, I think you missed the part about me setting up a DC power supply to verify the fan operation with straight DC. I might not have been clear.
BTW, the model printed just fine without support and proper cooling ! There are still some edge artifacts but I am positive they are related to uncalibrated pressure advance and they are very minor.

@jens55 nice one! Happy you found the problem! Take your time and go into calibration steps for extruder steps, PA, filament flow and you are good almost for ever. At beginning i skipped steps because i tought they were not needed, but in the end the difference is remarkable. More if you try to speed up things.

@mikes , this is an example of my corners now:
The corner is on the right side and is perfect. I started a separate thread about trying to reduce the oddities of the seam that you can see to the left of the corner.
