I just replaced some cracked printed parts on my Mini and added the damper to the Y axis and replaced the PEI sheet. I figured this would be a good time to re-hone my filaments to make sure I’m getting idea prints.
I’ve been able to get it close, but it seems like the first few layers aren’t quite perfect. Please see the attached progression.
The part on the far right is where I am now. The initial layer thickness is perfect. Calipers are measuring 0.43-ish, the 20x20 block is coming in at about 20.1x20.1 which is pretty darn close. However, it seems like the first few layers don’t match the rest of the print. It appears the corners bow up a bit.
My guess is this is a cooling fan issue. Currently it’s set to the Lulzbot HIPS recommended 50% in their profile. Does this corner curve indicate I need to turn cooling down a bit?
