Improving the fixture offset recording custom macro

Updated: May 21, 2019

Suggested by Alejandro Garcia of Extreme Machine, Inc.


In a previous blog post, we published a custom macro to record the settings for fixture offsets one through six (G54 through G59). The custom macro actually creates a program that will allow the user to reset fixture offsets to their current values at some future date. It does so by outputting the commands through the communications port using a DPRNT command.


While this program is very helpful, we recently had a request for doing the same thing with the extended fixture offset option (when users have a total of 54 fixture offsets). What follows is the program that does this – outputting the standard fixture offsets (G54 though G59) as well as the additional 48 fixture offsets. And again, a program is created that – when reloaded and executed once – will reset all fixture offset registers to their current settings.


Two notes:

First, the program uses system variables to attain fixture offset settings. As you know, system variables vary from one Fanuc control model to another. This program is for a 16M control. You’ll have to determine which system variables are related to your control if it is not a 16M and modify the program accordingly.


Second, and in similar fashion, the L word of G10 (which is being used to reload fixture offsets) also varies from one Fanuc control model to another. You will have to determine which L word is related to the extended fixture offset option and modify the program accordingly.
