Tormach 1500MX - Plane Selection (G17, G18, G19); Length Units (G20 and G21); Return to Predefined Position (G28 and G28.1); Return to Predefined Position (G30 and G30.1)

9.2.7 Plane Selection (G17, G18, G19)
To select the XY-plane as active, program: G17
To select the XZ-plane as active, program: G18
To select the YZ-plane as active, program: G19
The active plane determines how the tool path of an arc (G02
or G03) or canned cycle (G73, G81 through G89) is
interpreted.
9.2.8 Length Units (G20 and G21)
To set length units to inches, program: G20
To set length units to millimeters, program: G21
Tip! Program either G20 or G21 near the beginning
of a program, before any motion occurs. Avoid using
either one anywhere else in the program. It's your
responsibility to make sure that all numbers are
appropriate for use with the current length units.
9.2.9 Return to Predefined Position (G28 and G28.1)
To make a rapid linear move from the current position to the
absolute position of the values in parameters 5161-5166: G28
To make a rapid linear move to the G28.1 position by first
going to the intermediate position specified by the X~, Y~, and
Z~ words, program: G28 X~ Y~ Z~
Note: Any axis not specified won't move.
To store the current location of the tool in the G28.1 setting,
program: G28.1
G28 uses the values stored in parameters 5161, 5162, and
5163 as the X, Y, and Z final points to move to. The parameter
values are absolute machine coordinates in the native machine
units of inches.
To store the current absolute position into parameters 5161-
5163, program: G28.1
Troubleshooting
It's an error if:
l Cutter Compensation is turned on
9.2.10 Return to Predefined Position (G30 and
G30.1)
G30 uses the values stored in parameters 5181 and 5183 as
the X and Z final point to move to. The parameter values are
absolute machine coordinates in the native machine units of
inches.
To make a rapid traverse move from the current position to the
absolute position of the values in parameters, program: G30
To make a rapid traverse move to the position specified by
axes including any offsets, then make a rapid traverse move to
the absolute position of the values in parameters 5181 and/or
5183, program: G30 X~ Z~
Note: Any axis not specified won't move.
To store the current absolute position into parameters 5181-
5183, program: G30.1
Troubleshooting
It's an error if:
l Cutter Compensation is turned on
9.2.11 Automatically Measure Tool Lengths with an
ETS (G37 and G37.1)
Use G37 and G37.1 with an ElectronicTool Setter (ETS) to
enable automatic length measurement. For automated use,
add a G37 command after an M6 tool change commands.
If you're using the ETS with a mill, the input port varies
depending on your machine:
l
M Series Mills Plug the ETS into the Accessory Input 2
port. You can still use the Accessory Input 1 port for
other probes and accessories.
l
Older PCNCMills Plug the ETS into the (single)
accessory input port.
Move to G37 Position Over ETS (G37.1)
To move to the G37 position (over the ETS), program:G37.1
To set the G37 position:
1. Jog the machine over the center of the ETS.
2. From the Probe tab, on the ETS Setup tab, select Set G37
ETSPosition.
The read-only DROs in the ETSG37 Position Setup group
display the new position.
