What am I doing wrong?
-
I am new to 3D printing and just got a Creality CR10 V3, with a BL Touch. I managed to print PLA after a little trial and error.
Now I’m trying to print PETG and having problems. The prints are not sticking completely to the bed. I tried covering the bed with blue painters tape and that didn’t change anything. I have set the settings recording too many videos I watched on YouTube and just can’t get this figured out any help or guidance on where to look for help would be greatly appreciated. Thank you  image url))

Having the bed temp at 75deg with slower speed 40mm/s when I use PETG, fixed my bed stick issues .. (even slower 25mm/s for first 2-3 layers helps greatly) Ender 3 Pro printer.
Also .. different brands of filament has different properties. (bloody annoying)

I generally have better results with PETG than PLA on my CR-10 Max, however after some issues I did find that PETG sometimes needs a different z-offset than PLA and I also print with a bed temp of 70c with just some Magigoo applied to the bed.
Hope that helps.

Bed-adhesion with PETG can be tricky. Blue painter's tape is decent with an unheated bed, you could try heated bed with unscented hair-spray.
Also double-check your bed-level and z-offset, if it does stick in some places but not others.PS. Your images didn't upload when you posted, so they're not part of your post.
