Hello!
I require some help.
It could we hardware or settings problem.

Previous printer and current - I always (!!) get a corner lifting.
No idea what causes it, I have tried different temps on the glass and nozzle.

I don't have a pic right now, but its generally a corner that lifts, sometimes it just curves up, other times it just a dead lift and sits up no matter what.

Printing onto a mirror with a later of Kapton tape on it.

Head bed - 60 to 70 dregrees.
Generally first layer is 70 and other layers around 60 or 65.

Extruder is at around 185.
