I was working on my 1 yr old Shapeoko 3 when I discovered a tiny black screw on my wasteboard. It is .16 inches long and .12 inches in diameter with slightly double recessed ends. I have attached a picture. Any ideas where it may have come from? I thought I would ask the experts if they recognize it before I have to start taking things apart. I have a Dewalt 611 router and a Suckit dust boot. It looks like I may have seen it but I am unable to be sure,
Thanks Will,
It’s really difficult to see some of the x holes and get at them. What is the purpose of this particular screw? Is it to prevent slippage. Everything seems very stable - x,y, and z. Can a catastrophic event occur if it falls out?
I agree will Will, probably a set screw from the static pulley on the Z axis. Technically nothing should move even without that set screw. I lost one too last year, machine worked fine, I reinstalled it with blue loctite (242/243) when I had my Z axis apart.
As @DanoInTx noted it’s probably from the static pulley, which shouldn’t be able to move, being held in place by its bolt — I’d put it away as a spare so long as all the others are present and accounted for.
