Anyway, grabbing my table, I got enough movement that you could actually hear the oil on the dovetails making their suction sound. Tried tightening x to the point of it jamming, it wasn't X Moved onto Y. It's acting all kinds of crazy and after reading this thread, I decided I'd like to just pull the X and Y saddles and clean/inspect everything.
I suspect debris in the dove tails, I might even expect a loose ballnut where it connects to saddle.
Anyway, I don't see a diagram in my manual, any points/heads up would be helpful. I don't currently have the spanner wrench for the angular bearing adjustment, figured I'd just make one. I watched a video by NY CNC but they had an 1100. Does the 440 have the jut/jam nut on the X and then the bearings adjustment is WITHIN the stepper on Y? Maybe this is how 1100 is too...I'm not sure, He didn't go into Y adjustment. I might even think the ballscrew needs replacement which my machine was sold with one, but I'll have to figure out if its a X or X (I assume they are different lengths)
Not the way I wanted to start 2021, but after 2020, no surprise.
Thanks guys.
