Re: G28 G53

We also have one Haas mill which follows the Fanuc format. But since the code G91G28X0Y0Z0 sends the machine spindle to the far right hand machine home position, I do not like to use it.
Instead I use the machine coordinate system command G53.
(first program blocks)
G90G53Z0
G53X-15.Y0 (machine has a 30 inch X axis travel)
(last program blocks)
G53X-15.Y0
G0G90G40G80T1M6
M30
The fadal can run either format. If you set it to FORMAT 2 (been years, I think it's 2), it will act more like the HAAS, including G54 offsets instead of E1.
You can change the HAAS code and remove the X move so it won't move the table all the way over.
