ABS Printing and Fan

I printed for the first time last night with ABS. After the print finished, the Aux Fan kept running. I woke up this morning and it was still 100%.

Is this normal?

It may be as simple as the start and end gcode, or maybe you accidentally turned the fan on manually.

Did you change something, or use a profile from someone else?

I would suggest not running the Aux fan at all while printing ABS to avoid warping issues.

I do run it before the print to help heat up the chamber but it turns off as soon as the print starts.

You may be correct, I think I found out. I downloaded a file from MakerWorld and it looks like they turned on Air Filtration Enhancement.

I assume this turns the fan on after the print is done to 100%. I can’t seem to find any documentation on what that does.
