Great job , we had issues in the rear left corner with top layer print issues and small warping in other thread on was measured variations in the bed temp but not ideal and was not sure if it was the bed or some thermal issue in the left corner
I did tests with PLA 50C and ASA 110C both the same with PLA was able to solve it not ideal
Can you please bump it to 100C or 110C and take a few pictures lets say in the beginning and 5-10 minutes apart with more focus on the left rear quarter of the plate . It will be great to see the variation compare to center at start and how long it takes to become almost even or with in 2-4C
was not sure if it was the plate or some thermal cooling issue in the corner , but ASA is printed with no fans
Other wise i print PLA at 50C plate all the time
