Disable Reference Switches – This seng exists to provide a temporary workaround for a
malfunconing reference switch circuit. The Ref X, Ref Y, Ref Z, and Ref A buons now set the
machine reference posion to the mill posion at the me the buon is pressed instead of going
through the homing procedure.
NOTE: If desired, this procedure may be used in conjuncon with one or more dial indicators mounted at
the ends of mill travel to provide a more accurate method of manually referencing the mill.
G30/M998 Move in Z Only – The G30 or M998 G-code commands can be used to move the mill to
a pre-set posion. The posion is seable using the Set G30 buon on the Osets screen. A G30
or M998 command is typically programmed right before a tool change line in G-code programs so
that the spindle head clears the workpiece with sucient distance to be able to change tools. When
selected, this opon moves to the tool change posion in Z only, otherwise a coordinated XYZ move
occurs on G30 or M998.
Enable So Keyboard – If the mill is equipped with an oponal Touch Screen LCD Monitor (PN
35450), this provides a so keyboard for DRO and MDI entries (for inial setup and calibraon, refer
to Touch Screen Kit documentaon). When the mouse is clicked in a DRO eld, a numeric keypad
opens on screen (see Figure 6.16). When the mouse is clicked in the MDI Line, the Save or Save As
elds, or the conversaonal tle DRO, a so QWERTY keyboard opens on screen (see Figure 6.17).
Press Enter to accept the value that has been typed. Press ESC to exit the on-screen keypad and
restore the previous value.
Probe Opons – Tormach has two probes available: a Passive Probe (PN 32310) and an industrial
grade Digizing Probe (PN 31858). Instruct PathPilot which type of probe is aached to the mill
before using the probing buons. Refer to chapter 8, Accessories, to ensure correct probe is selected
before changing this seng.
Enable USB IO Board – The USB-based IO module (PN 32616) provides an extra eight points of
non-real me IO (four digital inputs, four outputs) that can be controlled via M-codes in a G-code
program. Refer to the documentaon that comes with that product for more details.
