The T command is used to specify the tool number required for the following tool path.

The tool number is used in conjunction with the M06 command, which performs the actual tool change.

The T command must always appear before the M06 command. If the tool number is specified after M06, the machine may behave unpredictably.

If the specified tool is already loaded, the tool change command will be ignored.

Syntax & Parameters

The T value defines the tool number to be selected.
