Total noob question - does the Snapmaker extruder module have a part cooling fan integrated?
I noticed there are two openings in the black plastic on the bottom directed towards the nozzle. I took the cover off the side of the extruder and looked at the fan, but for the life of me can’t tell where it moves the air to/from, or if it’s for electronics cooling, part cooling, or both.
Anyone have any thoughts on whether adding more cooling is helpful for PLA and PETG?
Reason I’m asking is because my prints are still coming out a little ragged. I’ve calibrated the extruder and run temp and retraction towers. I’ve also experimented with the layer height and speed settings.
I’m new to 3D printing, so maybe what I’m getting is typical, but so many of the prints shown on Thingiverse (the real pics, not the renderings) look SO much better than what I’m getting.
So, do you think more part cooling is a good idea, or is the integrated SM2 fan good enough?
The cooling fan IMHO is mainly for overhangs, where the plastic needs to cool down as fast as possible not to be pulled down by gravity. And for the few prints I did with Snapmaker overhangs were a pleasant thing - just worked across several centimeters. So I’d deem the fan good enough. Stand to be corrected…
Please keep us posted! And look around on Thingiverse and/or Facebook - I seem to remember that other users already created auxiliary fan mounts for SM2.
no but im bout to see if i can fit a noctua in there now … i didnt even know this damn thing had a cooling fan. this machine could be so much better if they would include all the settings we actually need in luban.
Hi,
reading through the forum, it seems that the part cooling fan is rather weak. But on my SM 2.0 it is so incredibly weak that I fear it is actually broken. I took a video where you can both hear and see some strange behaviour of the fan when sending the M106 P0 S255 to the device. Is this really the expected behaviour or should I contact the support?
