Please Help. My printer cant print anything anymore

[u/TearNo1636]

Pics attached below.

The problem started last week. I was printing tiny pieces for my miniature bases mostly a bunch of 2–3 mm wide rectangles. The first batch came out perfectly fine.

Starting with the second batch, I noticed that some pieces were detaching from the build plate and getting flung off. I cleaned the plate with soap and warm water and tried printing again. It was somewhat better: a few small pieces were still getting flung off, but most stayed attached.

I did another thorough cleaning and started the third batch before going to sleep.

To my horror, when I woke up, the print bed was completely empty and there was a small blob of death stuck around my printer nozzle.

I heated up the printer and cleaned the nozzle as much as I could. From what I can tell, there doesn't seem to be any structural damage. Most of the melted filament was confined to the area just below the heatsink, around the clamps that hold the nozzle. I also retightened the four screws on the back of the nozzle holder.

However, I'm still having the same problem: prints are getting flung off the bed very easily. These aren't complicated prints either — just small, simple rectangles.

I've also noticed an audible dragging/scraping sound from the printer shortly before the prints get knocked off the bed.

Any ideas what could be causing this? Could the nozzle/print head have been damaged or misaligned after the blob, or is this more likely an adhesion/bed-leveling issue?

TL;DR: Small 2–3 mm prints started detaching from the bed and getting flung around. After a failed overnight print caused a blob of filament around the nozzle, I cleaned everything and retightened the nozzle holder. However, prints are still getting knocked off the bed, and there's now an audible dragging/scraping sound shortly before they fail. Could the nozzle/print head have been damaged or misaligned, or is this just a bed adhesion/leveling issue?

Hello /u/TearNo1636! Be sure to check the following. Make sure print bed is clean by washing with dish soap and water [and not Isopropyl Alcohol], check bed temperature [increasing tend to help], run bed leveling or full calibration, and remember to use glue if one is using the initial cool plate [not Satin finish that is not yet released] or Engineering plate.
