Hi,
I've got a HF minimill with a Hoss design 3 axis CNC conversion and little machine shop belt drive conversion.
I'm having a major issue. The spindle head (the whole part that moves up and down) is deflecting SUBSTANTIALLY when i'm trying to make a cut.
The X and Y axes (fun fact, the plural of axis is axes) are tuned in well (as evidenced by the fact that tightening the crap out of the Z axis yield no backlash on the X or Y).
The amount that I need to tighten the Z so it doesn't deflect is WELL beyond how loose it needs to be to move freely.
Also, my belt is slipping on the belt drive. I'm not sure if this is contributing.
Help! Please!
