Is the fan on the 3D printing module that is facing downward intended to cool the part or is it cooling something inside the module?

@Tone , it is a good question. I’ve seen some prints/additions to direct the flow onto the print.

@Tone @CthulhuLabs now I’m curious which is the correct direction. I don’t think the stepper motors need cooling as much as the hot end or the print.

There are two fans. One is blowing across the heatsink for the hotend, the other as near as I can tell is blowing on the stepper motor. The reason for that is the stepper is in cramped space with the hotend. It heats up it needs active cooling. Neither of those dinky fans is enough for proper part c…

Mine is definitely blowing downward. I’m wondering if the other fan wasn’t moving enough air through the module and they decided to add the bottom fan to help out? Edit: The stepper motor really takes up about 75% of the cross section area there, the electronics takes up a bunch of the top area and…
