Hi,
with my old fanduct I had some rotten prints due to loss of steps, so I build an improved one.
The new one is very efficient now. Cools enuf at 20% fan speed.
... but as print objects are very different, it may occure, that die airflow will be reflected from the printed part and cool down the hotend.
Which in turn aborts the print with some error like the one in the second picture.
So I'd like to know, whether the gap, that aborts the print can be configured.
I don't know, if the heater is capable to reach temperature with cooling, but I'm confident.
To show what happens some pictures:
when the heater speeds up for a bridge, and support has enuf room to eat the airflow, heating recovers from cool down.
When support under the bridge reflects the airflow, this is what happens:
