Taz 6 print is peeling up

Hello, I have a taz6 using the lulzbot taz 6 cura default “standard” profile and my bigger prints are warping on the bottom layer any suggestions?

You look to have some pretty bad heater bed delamination going on from the yellow color of the middle of that bed. Will tend to cause the bed to be too cold there due to lack of heat transfer.

What material are you printing?

we are using HIPS
the lulzbot brand

We have only printed like 10 things

“schools printer” they got it about a year ago used it a few times then the lady who set it up left so it has been sitting dormant for about a year. I recently started it up again as i’m the only one who knows how to use it
