When I set up the machine I went by the Hurco manual that said to use a precision level on the table. I read in another post for Fadals that the the way covers should be removed, ways cleaned and to use them for the leveling process. I then saw on another board to level a vmc by leveling a surface plate on the table then adjust the leveling bolts til it trammed within .001 or better regardless of the way or table level. Any other suggestions?
