M07 – Low-Level (Mist) Coolant On

M08 – High-Level (Flood) Coolant On

M09 – Coolant Off

The actual implementation of these M-codes will be very machine dependent, but it will typically be very

simple. For instance, if the coolant on/off control were wired into Turbo PMAC’s Machine Output 7, and

the coolant high/low control were wired into Turbo PMAC’s Machine Output 8, the routines could simply

be:

N07000 M7=1 ; Set Mach. Out. 7: Coolant On

M8=0

; Clear Mach. Out. 8: Low Level

RETURN

N08000 M7=1

; Set Mach. Out. 7: Coolant On

M8=1

; Set Mach. Out. 8: High Level

RETURN

N09000 M7=0

; Clear Mach. Out. 7: Coolant Off

RETURN

DWELL statements could be added before and/or after the setting of the outputs if it is desired to provide

some time for the change to occur.

M12 – Chip Conveyor On

M13 – Chip Conveyor Off

The implementation of these codes, though machine dependent, typically will be simple. For instance, if

the conveyor on/off line were wired into Machine Output 2, these routines could simply be:

N12000 M2=1 ; Set Mach. Out. 2: Conveyor On

RETURN

N13000 M2=0

; Clear Mach. Out. 2: Conveyor Off

RETURN

M30 – End of Program with Rewind

See M02 description. M30 will be equivalent to M02 in most systems but will return to the beginning of

the program.

Default Conditions

Typically, a machine running G-code style programs requires many default values and modes beyond

what PMAC sets automatically during its power-up/reset cycle. To set these defaults, it is best to use the

PLC 1 program, which will be the first thing executed after the automatic power-up/reset cycle

(effectively extending what is done in this cycle). The last line in this program should be DISABLE PLC

1, which prevents repeated execution of the program. A simple file for such a program could be:

OPEN PLC 1

CLEAR

M55=0

; Spindle Off

P92=3000

; Maximum spindle RPM

P95=1000

; Max spindle accel. in RPM/sec

M70=0

; English measurements

DISABLE PLC 1

; So this is only executed once
