Ultimaker s3 issues

[mamastoast 0]

First time using the office ultimaker printer in a few years and we are experiencing some issue.

 

Can anyone spot the potential problem from these pictures? 

 

It was printed standing with the big part at the top, no supports. While I dont expect angles to be perfect, I know they should be printing more succesfully than this. Been a while since I used an FDM printer so I'd really appreciate any help you can give 🙂

A lil more information. This printer has previously printed spheres with very few issues. I dunno why it's decided to mess up at even small overhang angles.

I've tightened the belts on the printer(one was a lil loose, but fixing it didnt make a difference)
I've calibrated XY
I've tried printing at 190
I've cleaned the print core
I'm printing at 100% fan speed, PLA filament, entirely new spool.
I've tried printing at different layer height and speeds, doesn't seem to make a difference.

 

Tried printing upside down with supports, there is a distinct "stepping" going on

It seems like possibly your side fans might not be running in the first photo. Also, when was the Z-screw last cleaned and lubricated? The Z-shafts?

+1 for checking the side fans, debris like a loose chunk of support structure can get in there and jam them up. The printers can't report if the fans are actually running properly so you need to visually check.
