After working on some modifications to my Creality Ender 3 Pro I am starting to print on it again. Did some test prints with standard PLA and was able to print out a phone holder with it with little issues with adhesion to the build plate or printing issues in general.
However, I am now trying to print something much larger with PLA + (I need it to be a bit stronger, but PETG feels like overkill) and am having an issue with build plate adhesion. Attached is a photo of what it looked like when I stopped it, it seemed to have no problem putting down the skirt, but once it started printing the first layer for the box, it started pulling up and not adhering properly.
Was hoping for any suggestions or tips to help with this, or if you have had a similar issue and found a solution I would love to hear.
I am using a Wham Bam magnetic build plate that I am scuffed up with some steel wool and applied a gluestick too to help with adhesion. I am printing at 220 on the extruder and 65 on the build plate.
