Thanks Will! Even having another place to look is reassuring. I was worried my machine was connected to some kind of alternate dimension that spat out set screws. A technological marvel but of limited practical use.
Happy Sunday everyone!
I finally had a chance to make it out to the shop and take a look at the pulley on the back side of the z-axis plate. It was indeed missing it’s set screws, so I put them back in place with some loctite to hopefully keep them from backing out again.
Thanks again to everyone for their help on this!
I just had this happen to me. I spent an hour trying to find another pulley because every pulley had all it’s set screws…forgot about the fixed one on the z axis!
