I am a neophyte at 3D printing. My Ender 3 is now 4 days old and I modified it out of the box with a glass bed. My first print was a fairly complex item, but a mere 90 x 160 x 3.5 mm. Used the sample filament that was included with the 3, first print was a keeper.
Today I was trying to use the AmazonBasics PLA 3D printer filament. I am not amused. I'm using the identical setup and glass bed as before but poor adhesion prevented a print.
I cleaned the glass with acetone followed with 90 % IPA... No joy. Another cleaning using a dishwashing detergent and IPA, boo hiss!
The glass bed is a Creality for the Ender, purchased separately For the first print, no adhesive was used, just the glass (cleaned the glass prior to the first print as described).
