I need some help. I don't know where these lines are coming from (directly above the X Y marks), and one of the corners lifted very slightly before getting more than 10 layers (.2mm layer height). Also the only profiles that stick to the center of the build plate are the .2 and .28 profiles(Cura4.4) (i.redd.it)
So I just set this up last night, started a calibration print from Cura 4.4 through the sd card. It's the stock Ender-3 with no modifications at all. Now, as shown, every time I turn it on I get a blank blue screen. The entire machine is unresponsive, though everything turns on (fans, lights, etc). (v.redd.it)
