I have an Ender 3 V2 pro with the Quinly bed adhered to the aluminium bed.
I have a hard time getting my prints to stick well. (PLA as well as PETG). We finally found out that only increasing the bed temperature a lot helps a little. Only the edges have a very bad adhesion and even terrible warp.
Here are measurements from an infrared thermometer:
I kept the orientation and distance constant.
Is it normal that the temperature has such differences across the bed?
If not: What could be the cause?
And: How can this be solved?
