Screw fell out in the middle of a print

Posted · Screw fell out in the middle of a print

I heard something fall into the chamber in the middle of a print, I'm not sure where it came from



It looks like it may be one of the screws that attach the gears to the rods.

What is the best way to move the printhead around when the machine is off so I can spin the rods and take a look. I don't want to force anything.

    Yup, that looks like a grub-/setscrew from one of the pulleys (gears). With the machine off you can just grab the head and move it around. You can do this when the machine is turned on as well as long as the stepper motors have powered off. Or, if you want to be more gentle grab the black boxes that ride on the exterior rods and move them in tandem. (you wont harm the printer using either technique).

    While you're looking for the place to put the screw back in, take the opportunity to tighten all of the screws so this doesn't happen again. Tighten them hard.
