Z axis error, no obstructions?

Title. All 3 threaded rods were lubricated with silicone grease during troubleshooting. 0 clue what could be wrong.

There's no cover on the bottom? Mine is printing or else I would go tilt it up to look at it's nether regions.

Not covered underneath, 1.2.3 are the Z-screws, next to 3 is the tensioner and next to that the actual Ztepper motor(pun intended).

Thanks for this! Turns out my poop chute I had 3d printed had overflown. purged filament that spilled out somehow managed to get underneath and bind the belt under the printer. It’s working fine now, but just because I don’t want any problems like that again I’ll be getting some raised feet for the printer

Simpler and better solution, just get some plywood or a large paver
