Overhangs and bridging are bad with filament that need strong cooling (PLA, TPU) on higher speeds

[tankanickel]

If you try to print PLA/TPU or other materials that need stronger cooling with higher speeds, the afterburner cooling solution is not pushing enough air to cool the material fast enough. This is an inherent flaw with the afterburner. (this issue does present itself even with open doors)

The only solutions are AFAIK:

• slow down the printing speed (no 5 minute nice looking benchies for you)
• change the toolhead solution to the stealthburner (involves some costs, wiring work, changed settings and a new motor)
