Prints don't stick in the middle
I have my prusa for about 1 month.
In this month, the only thing i do is troubleshooting.
It takes 2 weeks befor the calibration worked, every time i get an error message. All was build correctly. The solution was, calibrating without nozzle. After a few tries, the calibration was working.
Now i have struggle with the heatbed. In the center, the print doesn't stick to the bed. It's like an circle of 6cm.
I have replaced the pei sheet with a new, no effect. Every time i clean the bed with alcohol. The rest of the bed works nice, but not in the middle.
I'm not shure, but it feels like the center is a bit colder then the other areas on the bed.
The bed is not bended, the surface is flat.
I think it's a bug in the auto calibrate function or its to cold in the center?
Anyone got an idea to fix this?

look (& read !) here.
and especially take attention about the cleaning hints.
if you think that your heatbed doesn't heat up in the middle, the only way to check this is with an infrared thermometer.
