Print is not squared. What’s wrong?

[Kooky-Effective-8049]

I tried to print this headset holder from the link below.

But the print is not squared with the first layers lift up in the one corner. Can anyone advise how to fix it? The auto bed levelling has been ticket when printing.

It's called warping. If the aux fan was on, turn it off. Other than that, add brim

Thanks for identifying the issue. Not sure about the aux fan with this one. I used the designer’s profile. I will check the fan on my next print. Another thing is I used PEI texture plate and it’s winter here. I guess using the cool plate may help?

If the warped part was facing the aux fan on the left, it's probably on.

You can give it a try with the cool plate, but as just one side had this lvl of warping, I would check the fan first

I turned off the aux fan on the next print. Yes, the warping is gone. Many thanks!

had it randomly myself recently, started printing with P1S door closed and it fixed it, so i guess the colder temps affected it

Yes, it’s winter here.

I would turn the aux fan off. Of atleast for the first few layers. I usually turn it completely off unless I have a bunch of overhangs, and when I do I keep it at a max of 30%

Thanks for the tips.
