Petg starts lifting at the corners

I found that my print started to lift at the corners, so I switched to my glass build plate for better adhesion and raised the temperature of my print bed to a whopping 85 degrees, that seemed to solve the problem. But when I came back the next day the corners are almost lifted by a centimeter, what can I do more to fix this. It’s I pretty big print, so chances are the heat bed still doesn’t really get to the corners.

Add brim or better mouse ears if theey fit, make sure there is no air movement while it’s printing keep enclosure closed and warm.

+1 for the Brim. I switched most of my prints to a brim to make sure that the corners were good. After the print I deburr it.

Thanks guys, will check at next print, I’m letting this one finish because it was already halfway, and it uses 400 grams in total. The corners are not crucial, but it is ugly.

Print first layer a bit slow,
Brim, brim and brim…
or you can add small rounded feet to the first layer, they act like a brim and are easy to remove. there’s a Cura plug in for that if you use Cura.

Deburring what got annoying for me quickly :slight_smile:
I went with this - https://youtu.be/MCcFMDv_4eo

This is awesome! Thank you for sharing

Pulling out this old thread.

How are mouse ears possible in Luban? I have some larger things to print and don’t want to waste that much filament and time for a raft on the whole object.

But i can’t find how to add mouse ears only to my object i want to print

Use another slicing software ,This little thing can be added quickly and easily
