X/Y bar movement off of belts?

Recommended Posts

Not sure what to call this one. This is what I came into this morning after doing an all night project:

This is actually a 2nd print job. It did it on a long job over night, so I reseated the bar on the black pieces on both sides and ensured it moved appropriate and then started this 30 minute job. Came back to check on it later and this is what I walked into.

The bar (Y axis, i guess) has slid completely back past the belt that moves it back and forth.

What causes this / where do I even start with trying to fix it? Just putting the bar back on the black pieces on the belt didn't do it, so there's got to be something else causing it.

Nevermind. The printcore housing won't close all the way (the magnet won't engage) so I'm using the rubber bands to hold it closed so it doesn't fall open during a job and one of them got caught in the hole the pole goes through the carriage. Just means I need to figure out the housing problem sooner rather than later.

Try this fix for the fan bracket issue. It's soft metal; if it gets bent out of 90 it doesn't close well; you should be able to bend it back to 90 degrees with a little force.
