adhesion problem

Hello

Im using a brand new steel sheet with powder coating (cleaned once with isopropylalkohol), the PETG filament is dried -

but the adhesion is crazy bad. 

why? 

I'm printing plates, with a big footprint... so adhesion shouldn't be a problem at all... 

 

thanks

Did you adjust live z? Textured and satin sheets are about 0.4 mm thinner than plain steel sheets. Also, I'd give the sheet a good rinse with hot water and dish washing soap to remove any residues.
