Guys I just finished my build with a 48x48 router using a ess smoothstepper gecko 540 warp9 running mach4 and when cutting a rectangle my Y axis (bridged/slave) doesn't repeat and leaves about .06 between .125" depth cuts cutting a rectangle that is 5x9. I cant imagine that backlash is causing this. when I step back and forth with a indicator using .01 steps it repeats. I'm at a total loss. if anyone can shed some light on this I would be greatfull
