Hi All

I bought a CR-6 MAX few weeks ago, and got into PETG printing last week. Since than I've had this situation on certain spots over the bed. I've changed certain parameters in Cura 4.8 like retraction distance and speed but still on that large piece at the end of the first layer I got this things (see picture).

Can someone give me a hint on what may cause this??

PETG nozzle temp at 235 and bed 85, glue all over the bed to have a film for helping removal of the part after print

New to the 3D printing world and learning the hard way, I have this situation with PTEG and would appre3ciate help on this. First panel I printed with PETG was worse, by tweeking retration I ended up almost perfect up to this point where it looks like for some reason it does not adhere to bed.

PETG with nozzle temp at 240 and bed at 75

Any help indication on this would be much appreciated, Thanks!!!
