Ender 3 V3 SE PETG Printing help

Hi there,
I got some Creality CR PETG yesterday and I have been trying to get it to print. I printed a temperature tower and it seemed good until I looked at the bottom. There was an unintended recess in the part. I have tried to print other things but there is gaps in the first layer extrusions. I have tried levelling the bed with no luck. Gluestick doesn’t help either. Does anyone have a good orca slicer profile for PETG?

Morning,

I havent printed with PETG yet, but I ordered a roll and should be delivered later today.
Its sunlu PETG though, but will let you know my experience with…

Sunlu PETG is great, I get through kilos of it. It is the only white PETG that I would keep going back to, great for printing ghosts.
