M99 Sub-Program Return or Loop
This code is used to return to the main program from a subroutine or macro, the format is M99 Pnnnn (Pnnnn is the
line in the main program to return to). It will cause the main program to loop back to the beginning without stopping
when used in the main program.
Programming Notes - You can simulate Fanuc behavior by using the following code:
calling program: Haas

M99 With Macros - If the machine is equipped with the optional macros, you can use a global variable and specify
a block to jump to by adding #nnn=dddd in the subroutine and then using M99 P#nnn after the subroutine call.
M101 MOM (Minimum Oil Machining) Canned Cycle Mode
M101 tells the system to start MOM whenever the appropriate G-Code Canned Cycle is encountered (G73, G74,
G76, G77, and G81 thru G89). Oil is dispensed for the on time duration whenever the tool is at the R-Plane.
I(on time): Canned Cycle Mode
On Time: Squirt duration in seconds (0.050 is 50 msec).
M102 MOM Mode
M102 tells the system to ignore the G-Code Canned Cycles and dispense oil whenever M102 is encountered in the
program. Oil is dispensed for the on time duration at a periodicity dictated by the Time Between Squirts MOM.
I(on time) J(cycle time): MOM Mode
On Time: Squirt duration in seconds (0.050 is 50 msec).
Cycle Time: Time (in seconds) between squirts.
M103 Cancels MOM Mode.
M103 tells the system to cancel both Canned Mode and MOM Mode (no oil will be dispensed via MOM).
M103: Cancels MOM Mode.
M109 Interactive User Input
This M code allows a G-code program to place a short prompt (message) on the screen. A macro variable in the
range 500 through 599 must be specified by a P code. The program can check for any character that can be
entered from the keyboard by comparing with the decimal equivalent of the ASCII character (G47, Text Engraving,
has a list of ASCII characters).
The following sample program will ask the user a Yes or No question, then wait for either a “Y” or an “N” to be
entered. All other characters will be ignored.
