Just wanting to know if this post would work with mach3 for tool change position.
It is for 4 Axis Fanuc.
When I simulate in FC, it doesn't show that the machine moves in Y to home for the tool change.
Z retracts and X remains put. Which is what I want. But really I need the Y axis to move back, or go Home to facilitate tool changes.
Am I forgetting something here? Here is the 2 processes of interest.

Maybe something like this?
You can keep your rotary the same as you have it.
[: prgm_stop=false] There is no space between the : and prgm, if I did not put one it would show up as a smiley face like this

Good Luck~!:cheers:

Thanks fo the reply and the code. I will try it today and see what happens. Their is no quicker way to destroy a cnc machine than to mess with the post processor. I hope everything goes well.

[Perfect Circle]

YES! Please Make a Copy of your current post and mess around with the copy.
Be safe!
Do you know how to use the debug mode in FC?
Ctrl right click the bottom bar and a window opens, there will be the option.

"Set XBuild debug options"

Ok, I'll give it a try. Thanks again.

[hjl4]

Works. Thanks Perfect Circle.

Awesome!
Happy to help.
