Struggling print warping with pet-g

I am doing the auto bed level mod for the A5 and am struggling on the cover corners with PET-G. Looking for some advice to improve... from left to right I tried temps of 210 to 225. Fan at 20%. No issues sticking to the bed, it starts a few layers up. I am also using supports.

Warping with pet-g

    I’m not really sure why you’d be getting such bad warping with PETG. Maybe try turn fan off altogether? And try fan at 100% too? Looks like problems with overhangs and/or possibly overextrusion. What layer height? How cold is the room the printer is in?

    tried layer height of .2mm and .1mm. room is kind of on the cold side I would say but not that cold. I will try with no fan and then with the fan at 100 and see.

    If its just warping the 100% fan print should be significantly worse. If not, its something else...

    It got better... it might be the fan duct I just switched to... I’ll try putting the blow hard back on.
