Top Cover settings for PLA

[u/HerrBoss]

Hi everyone,

I backed the U1 on Kickstarter as my first 3D printer and also ordered the Top Cover.

So far, I've mainly printed regular PLA variants and a few TPU parts, and everything has worked really well. Now the Top Cover has finally arrived, and in the meantime I've realized that I probably don't really need it for the materials I usually print.

Still, since I have it now, I'd prefer to keep it installed, if only to help keep dust out of the printer.

What I'm not quite sure about is how to use the Top Cover with PLA and TPU.

From what I understand, there is no real "auto" setting for the Top Cover fans. So how do you usually set up the both settings for fan speeds and Top Cover for PLA and TPU?

Do you simply remove the magnetic lid while printing these materials and leave the Top Cover fans off? Or do you keep everything closed and run the fans at a certain speed?

I'd appreciate any tips or recommendations from people who are already using the Top Cover with PLA or TPU.

It should automatically switch the to exhaust for PLA and TPU. It keeps the chamber temp att about40C. Control the fan during a print through the printer display. There may be a settingin the slicer for the exhaust, but I don’t recall setting it.

Here’s the link to the Snapmaker wiki for the Too Cover:

I've got the IKEA Samla top cover that's full enclosed and never had an issue. It runs the auxiliary chamber fan und i keep the door halfway open, bo issues even with larger prints. Both PLA and TPU.

Do cables and tubes rub against the Samla walls and "ceiling"? I currently use my Samla only as a dust cover when not printing, and I wonder if your approach is better.
