Changing Axis Movement Speed
1.
Press HIGH/LOW to toggle between fast and
slow speeds.
Changing Axis Movement Mode
1.
Press MODE to toggle between Continuous,
Step, and Distance modes.
— In Continuous mode, press and hold axis
movement buttons to move axes. Release
button to stop movement.
— In Step mode, press button to move axis
one step. Step size is determined by
speed mode.
— In Distance mode, press button to move
axis a user-defined distance. Set distance
by toggling to Distance mode, then input
distance and press OK. Controller will dis-
play current setting.

Homing Axes

Homing the machine returns all three axes to
"home" position or the machine-specific zero
point. Home is determined by magnetic limit
switches and will not change. Since all machine
movement is calculated from home, always home
axes and verify machine parameters before each
operation.
To home axes:
1.
Press HOME. Verify all axes move to their
farthest positions.
2.
Verify all machine parameters listed in
Verifying Parameters on Page 23.

Setting Origin

Work origin is the workpiece-specific zero point,
the starting point for the toolpath. All three axes
need to be zeroed at the work origin before run-
ning code.
The Z-axis can be set in relation to either the table
surface or the workpiece surface, but it must cor-
respond to what is established in the G-code. If
this is not done properly, the cutter may crash into
the material or the table, causing damage to the
workpiece or the machine.
Set work origin before each unique opera-
tion. The work origin of all axes must match
the origin of the toolpath established in the
G-code. Failure to set the work origin may
cause the cutter to crash and damage the
workpiece, machine, or cutter.
Setting Work Origin
1.
Clamp workpiece to table, insert cutter, and
load G-code onto controller.
2.
Manually move X- and Y-axes to toolpath
origin established in G-code.
3.
Manually move Z-axis down to
workpiece or table surface (as determined by
G-code).
4.
Place piece of paper between cutter tip and
surface. Slowly step Z-axis down while slid-
ing paper until paper cannot move.
5.
Press XY->0 to set X- and Y-axis origin.
6.
Press Z->0 to set Z-axis origin.
