96-8000 rev R June 2007
M80 / M81 Auto Door Open / Close
The M80 opens the Auto Door and the M81 closes the close the Auto Door. The control pendant will beep when the
door is in motion.
M82 Tool Unclamp
This code is used to release the tool from the spindle. It is used as a maintenance/test function only. Tool changes
should be done using an M06.
M83 / M84 Auto Air Gun On / Off
An M83 will turn the Air Gun on, and an M84 will turn it off. Additionally, an M83 Pnnn (where nnn is in millisec-
onds) will turn it on for the specified time, then off automatically. The Auto Air Gun is also manual toggled on and off
by pressing “Shift” followed by the “Coolant” button.
M86 Tool Clamp
This code will clamp a tool into the spindle. It is used as a maintenance/test function only. Tool changes should be
done using an M06.
M88 Through-Spindle Coolant On / M89 Through-Spindle Coolant Off
The M88 code is used to turn on the through-spindle coolant (TSC) option, an M89 turns the coolant off.
Proper tooling, with a through-hole, must be in place before using the TSC system. Failure to use proper tooling will
flood the spindle head with coolant and void the warranty.
Running an M04 (Spindle Reverse) command with TSC on is not recommended.
Sample Program
Note: The M88 command should be before the spindle speed command.

M95 Sleep Mode Sleep
Sleep mode is essentially a long dwell (pause). Sleep mode can be used when the user wants the machine to
begin warming itself up so it can be ready for use upon the operators arrival. The format of the M95 command is:
M95 (hh:mm)
The comment immediately following the M95 must contain the hours and minutes that the machine is to sleep for.
For example, if the current time were 6 p.m. and the user wanted the machine to sleep until 6:30 a.m. the next day,
the following command would be used:
