G-Codes and M-Codes for MASSO
MASSO G- and M-Codes are the same as the industry standard. However, the MASSO software is different than other controller software in some respects.
All of the MASSO tool information is hard-wired in the control software, which is unique. Because of this, MASSO does not use G43 (tool length offset) or G49 (cancel tool length offset). To change from one tool to another, you only need to enter “T (the desired tool number) M06.” Example for tool #1: (T1 M06). Regardless of the current tool in use, or its position on the machine, when you enter the (T_ M06) command and then change your tool, the MASSO control will do all of the calculations and changes internally and move the next tool into the correct programmed position.
NOTE: The (T- M06) command MUST be in this order. A command of (M06 T-) will not work.
Below is a list of all of the MASSO G- and M-codes that can be used on our machines, along with their definitions. These are the G- and M-codes that are used on our Accu-Pro Machines and our original MASSO machines with the G2 board.
For a list of the G- and M-codes that are used on our machines with the Linux control, go to our G- and M-Codes for CNC page. You can also find more information on the MASSO G- and M-Codes at this link: Supported G-codes
