I printed a roll of cheap black ABS ($10/roll on amazon), and found my printer didn't work anymore. The cause was a significantly expanded nozzle.
New Rule...Have lots of spare cheap brass nozzles. Use a new nozzle every time you change nozzle size.
The dull grey is Amazon basics PLA, the shiny grey is Ebay cheap grey. The Ebay stuff has poor adhesion (for PLA), is super fragile (filament breaks every time i weigh it), but looks great.
Both cheap filaments have horrible bridging. The cheap grey is so bad I had to add extra layers on top.
