[Info] Fusion 360 - Setting Home Coordinates / Machine Profile

This came up in another thread, but thought I’d create a dedicated spot for reference. The default Fusion 360 (F360) post-processor will end a program the Machine Coordinate System 0, 0 (x=0, y=0). This can be seen in the processed g-code G53 G0 X0 Y0. For some, that can be an unwanted behavior.

I solved this by creating a Machine Profile within F360 (Machine Library), and setting the Home Position for both X and Y (Z is already set to 0).


This will change the G53 output to something like G53 G0 X400 Y500 (X and Y will be the values you set within the profile).

In addition, there are some other things you can default within the machine profile, like which post-processor to use. If you’re like me, and have multiple machines you post-process to, this can be a nice default to set (save your self the sanity of wondering why your probing operation is gone crazy, only to realize you were post processing for a different controller).

I’ve attached the profile (.machine) file, for those interested as well. Note, I’ve slowed down my rapids on X/Y if you use this, adjust accordingly.
RENAME THIS FILE - REMOVE THE .NC (I had to add that to get around the file type permissions :wink: )

Thanks Tim - aside from the super simple way of doing this in Fusion (<-- joke), will it affect the origin for cutting? I hope not, but just checking.

No, this is all within the machine coordinates system (MCS). When you zero on your part, you’re doing that in the work coordinate system (WCS). So all cutting is relative to WCS.

Also I’m sure there’s other ways within the Post Processor to adjust these settings, but I was just goofing around, and stumbled across this and figured I’d try it, and it worked :smiley: - as I was getting tired of the unit returning to the front left corner after each process (I prefer a machine to finish away from where I’m standing :wink:

This feature (at least in the post processor I’m using) is hardcoded. However, it’s really fairly simple to modify the post processor .cps file to have the machine go wherever you want. There is a function towards the end of the script called “onClose()” where you can input whatever coordinates you’d like other than 0,0,0.

I was looking at exactly that, but didn’t want to have to maintain a separate version of post-processor (though I think I will anyway) - and I prefer things to be parameterized. But good call.

Also - the machine profile works across different post-processors - which I’m facing currently while I test my other controller (GRBL).

Yeah, that is what I was going to do. Just haven’t gotten around it it.

There should be a way to make those parameters and have them show up in the list GUI. Haven’t done it personally. But now I’d like to try.

This should do the trick…
