Well, they say the grass is always greener on the other side.
My FLA (Fine Line Automation) 100 works very well on flat work and v carving. I am starting to do a lot more 2-1/2 D carving projects, and my machine seems to bounce a lot at feed rates of about 100ipm in x/y and 20 ipm Z. I have tightened everything up, including the bearings on the ways, and the issue persists even with new cutters. If I slow it way down to 50 ipm or less, with a plunge rate of 5, everything is more or less okay, but that sure makes for a long cycle time.
So I am looking for ways to make my machine more rigid. I see that Mechmates and Joe's Hybrid CNC both use v bearings, with either a dual gantry (Mechmate) or a gantry that grabs on the backside (Joe's), so I am wondering if it is a good idea to redo my machine to incorporate both the v bearings and some version of a dual gantry. Would it also be effective to change the z slide for a K2 z slide?
Have any of you refitted a FLA 100 with v bearings? How do you like the redo? Or alternatively, those with v bearing machines, do you like them, or do you long for some other method?
Ahren or Nate, do you have any secret hardware for doing this?
