I solved much of my problems by carefully leveling the print bed. I use the paper method but I use a thin sheet and got better results (22# copy paper seems to be too thick).
I also replaced my print bed with glass and wipe it down with isopropyl alcohol before each print.
I get much better results without using glue or hair spray.
I usually print PLA nozzle 205 and bed 65 with a brim and it stick very well.
I had A LOT of trouble getting adhesion when i first began this trip…switched to a glass plate, I set the temp at 70 and i LET IT WARM UP for a awhile. Check the temp with a contact thermometer. If I start to have adhesion trouble I wash the glass with hot water and dish detergent. Rinse well with cold water and let it dry ON the machine - don’t get fingers all over the glass. Also tramel the glass with copy paper for .4 nozzle, parchment paper with .3
If your z offset is adjusted.
In your slicer, set:
Initial layer height to 0.2
Initial layer print speed 15mm/s
Initial fan speed 0%
You can use a brim for more adhesion
