SETTING X-AXIS BACKLASH
When re-installing the X axis servo, it will be necessary to reset the backlash. Backlash should be adjusted to .003 using a dial indi-
cator.
1. Re-install the servo and adjust inial backlash unl most of the play has been removed. Tight-en the four bolts holding the ser-
vo assembly adjustment plate.
2. Place a dial indicator with the dial on the side of the Carriage.
3. Enable the servo, now give a rm "shove" to the carriage in one direcon and zero the dial. Then "shove" in the opposite direc-
on and check your dial reading.
4. Adjust the backlash by loosening the 4 bolts holding the servo assembly adjustment plate and moving the 1/4-20 backlash ad-
justment bolt located just above the servo assembly adjustment plate (see photo below).
5. Tighten the 4 bolts holding the servo assembly adjustment plate and perform steps 3 & 4 as necessary to achieve .003" back-
lash.
6. Re-home the machine.
NOTE: If the adjustment is too loose the machine will not cut accurately. If the adjustment is too ght, the servo may make a
"whining" noise.
