UM3 bed-screw cautionary

Recommended Posts

Posted · UM3 bed-screw cautionary

Last firmware update killed auto-leveling with me, but apparently manual leveling comes with its own risks.


TL;DR: Z-screw fell off during a print, and ultimately the glass build plate was thrown a good 2-3 feet out of the printer and onto the floor. Check the tightness of your z-screw if you are manual levelling.




Not sure when it came off, I'd printed two of the same print previously so I didn't give it as much scrutiny this time. First it destroyed the $100 buildtak plate I'd mounted 10 days ago to compensate for the loss of auto-levelling; flicked the build-plate off and then started scarring up the heated plate element.

      Through this post I would like to further explain what we are doing, and what you could be doing. 
      Our efforts consist of 2 layers. First; connect medical institutions and hospitals to (local) 3D Printing hubs to help them print parts of which a 3D model already exists. And second, contribute to design the necessary part and then have it printed via a (local) 3D printing hub. Experts are available from within Ultimaker and from within our network of 3D printing experts.
