Part 1

Insert the cutter into the hole in the cutter holder, and

use the hexagonal screwdriver that comes with the

machine to tighten the cutter mounting screw.

Head

Use the height setting made in step 4 to set Z0. Z0 is

the reference point for raising and lowering the

spindle.

Refer to “Setting the Z0 Position.”

Bottom of the head

Rotate the dial in the direction of the arrow shown in

the figure to extend the cutter to the engraving depth

(cutting-in amount).

Move the cutter out just enough for the necessary

engraving depth.

The lines printed on the dial indicate 0.0254 mm

(0.001 in.) for each mark. For instance, to set a

cutting depth of 0.5 mm (0.0197 in.), rotate an 20

mark portion.

Engraving depth

Raise the spindle with the [+Z] key.

Surface of

the workpiece

When setting the engraving depth with software, set a depth

about 2 mm deeper than the depth that would be set on the

micrometer dial. (In other words, 2 mm deeper than the actual

engraving depth.)

Engraving can be done at a standard depth by increasing the

force on the workpiece from the top.

When using the depth regulator nose to perform engraving, the

Z1 point (the tool-down position) is set to a height lower than

the actual engraving depth.

As a result of this, Z1 may be set to a position lower than the

surface of the table.

At this time, the error "Bad Parameter" appears during

engraving, and operation stops. To clear the error, switch off the

power.

To avoid errors, place a flat board under the workpiece to serve

as a lifting base.

Use a board of the following thickness.

Thickness of board placed under workpiece

> [Z1] - [Workpiece thickness]

A thickness of about 5 mm (0.2 in.) is appropriate. If the board

is too thick, the Z-axis operating range (30 mm (1.18 in.)) may

be exceeded, making engraving impossible.
