Prints not sticking to new Borosilicate bed
Hello Just replaced worn out stock bed that came with Ender 3 Pro. Had many successful prints with that bed. But even with cleaning it had too many ghost images and started to need a comealong to remove prints. So I ordered a Borosilicate glass bed and new updated adjustment springs. I cleaned bed, heated it up to 60 and checked for flatness. I'll have to say it is flat. What my problem is the Cell phone case I've started 3 times all failed. would not stay stucked to bed. When I restarted the print, it would lay down these brim lines. When the hot end got to the rear of the bed, this first strings would not stick. when it got to the front, it stuck. I even adjusted bed lil higher on back left and right corners. Made nice curves on the front but the rear didn't stick. Do I need to add some kind of stickum of some sort to the bed? Ender 3 Protried CURA 4.1,4.4,and 4.5(4.5 locked up a lot of times)Bed temp 200extruder 60, 4mm nozzle0.1220% infilwith BRIM without BRIM no differenceSkirt same results

the starting height is not set correctly. You need to follow whatever process the print manufacture gives you to set the initial starting height also called Z offset If the bed is level and the height is correct then PLA should stick to glass.
Once complete the attached model should be printed and the height of the walls measured with a digital caliper. The walls should be between 2.98 and 3mm tall if you are properly set up. If this is true when printed in the center of the bed. Place a model on each corner and measure them one at a time to check level.
Good luck it is a bit of a process but required if you want thing correct.

Ive never had an issue before. Could it be from adjusting the Z limit stop to compensate for glass thickness?
