This works on engine lathes, milling machines, routers, lasers, 3d printers, etc...anything CNC that uses G-code.
It is rare for anyone outside of manufacturing facilities to take advantage of the 6 work offset G-codes G54, G55, G56, G57, G58 & G59. These work for CNC router, laser, 3D printing, CNC milling and any other system that uses gcode.
Once you understand how to use them, your tooling and position setup times will be almost eliminated. Especially if you want to run production work.
Wondering what these little known g-codes are?
G54 to G59 are work position commands that, once set in your cnc, will retain the XYZ coordinates you set. Each G code can be set to a unique position in all axis. Your various workpieces can have fixed locations that can be called up anytime, eliminating setting the coordinates to zero.
→ You can set up multiple work stations on one work surface.
→ You can use the exact same program in multiple places
These work offset codes are perfect for someone that is trying to make money with their cnc and runs production work. They allow you to dedicate and fix the job position without adjusting after running other jobs.
If you use a 1/4" endmill for a particular type of job that you run often, the zero points of the job and the tool tip can be set to the zero reference point. In this case, there is no zero position setup.
HOW TO SET UP A WORK OFFSET
To set up a work position offset, decide on what code will be dedicated to that position (ex. G59). Enter that code into the command line. It will show up on your screen as an active 'G' command. Position your tool to the zero point you want to use. Then zero all axis. This is now set until reset the zero position for that code.
Reposition your machine with the next tool at the next zero points. Enter in the next dedicated work offset G-code and zero all axis.
IT IS BEST TO LEAVE ONE WORK OFFSET G-CODE FOR OPEN USE AND ODD JOBS...TYPICALLY G54 WILL NOT BE DEDICATED TO A POSITION.
