hi, i am a fadal service technician(9 years)
you must first power down.
unplug the scale from card 10 in the nc rack.
power on, and cold start
remove 4 screws holding the front way cover
put an indicater at both the end of the y ballscrew and in the spindle against the table
at control enter bl,2,0,0,0- zero backlash comp
move y axis .001" zero both indicaters
move y back to zero
if the table shows .005 and the balscrew indicates .004 then your thrust bearings have .004 slop and your ballnut has .001 slop
your glass scale will cause shaking if your combined backlash is greater than.0015
if you have any questions, email me at
