Topic: SD2 first layer becoming detached

I am running an SD2 with a glass bed and it's been great for almost a year that way.  Recently, all my prints are coming out with the first layer or two not securely attached to the rest of the print.  I end up peeling them off almost like brim.  Has anyone seen this happen?

The bed heater seems to be working - I get the same temperature on it that I have in the past.  I've leveled the bed and used the same gap that I've always used.  And so far it doesn't seem to matter what spool of filament I'm printing with, it still happens.

None that I'm aware of.  I typically only set brim on/off, support material on/off.

Re: SD2 first layer becoming detached

Are you letting the heated bed cool all the way before removing?  I sometimes get this issue when using smaller layer heights (0.2mm and below).  If possible, set your first layer height a little taller and it should help.  Or back off just like 1/4 turn on your Z stop and it won't be quite as smushed on and will come off easier.
