Using the Engraver Option 19
Changing the cutter rpm
The engraver motor runs at a constant rpm, so to change the cutter rpm, you
move the belt to another pulley on the top of the spindle. The Engraver Option is
shipped from the factory with the belt around the center pulley for medium rpm.
Moving the belt to the top pulley changes the cutter rpm to maximum or high
speed. Moving the belt to the bottom pulley changes the cutter rpm to minimum
or low speed.
WARNING: Set the engraver motor power switch to off before performing
this procedure.
1. Open the engraver cover.
2. Determine the present
rpm.
3. Loosen the two motor
bracket mounting screws
and slide the motor to the
left to reduce belt tension.
4. Move the belt to a
different pulley.
CAUTION: When
performing the next step, do not stretch the belt excessively. Only slight
tension is required on the belt. Too much tension can damage the
spindle bearings.
5. Slide the motor to the right until the belt is snug and hold the motor in this
position.
6. Tighten the two motor bracket mounting screws.
7. Turn on the engraver motor power switch.
