Ohhh @StephanK just beat me to it!
Do you remember when your prints started warping @Jinja?
Are you sure it happens with PLA too, have you also used ABS?
It would be helpful if you could include a photo of what a warped print looks like, and how your first layer looks like.
Have you tried using both sides of your glass plate?
The side with the warning-sticker offers you the best adhesion.
How do you clean your bed?
Looking forward hearing from you!
Lets see if i can be of any help till the pros show up ;-)
60°C bed temp should be more than plenty for PLA. More doesn't make it better in my experience. Did you try 50°C?
What are you using to clean your buildplate? Been using window cleaner at first. It apparently left some residue that needed a good wash in the sink to get rid of. Ever since all i am using is isoprop alcohol 70% or higher on a paper towel.
I'm getting mixed results with the standard nozzle height procedure as well. Starting from there, I usually just go ahead and turn the 3 knobs some more during the 1st layer of a test print in order to squish my first layer down even more.
Can you take a picture of your first layer?
