I have a kg1414 from k2, and for the most part I have been happy with it. I am using it to make some pretty delicate cuts, and the vibration in the y axis (large axis that moves the gantry) is affecting the surface of those cuts. The vibration is definitely not from any cutting process. It is the same when not running the spindle, and the cuts are extremely light on very soft material.
These vibrations would probably go unnoticed for most woodworking applications, but they have forced me to slow down my process considerably. Any advice that anyone can give me would be greatly appreciated!!
(The kg1414 y axis uses square rails, one on each side, attached to an aluminum extrusion frame)
