Error I have never had before

Hi Folks,

I am using Fusion 360 w/ the standard LinuxCNC [EMC] post.
I am getting an error I have never had before:

"Can not use G53 with cutter radius comp"

I did change my ini recently to include G54 to do toolchanges in a more convenient place, (can that cause this???)

I'll attach the ngc if it helps.

Thank in advance

I see an airplane in your logo.

Maybe first do G40. Then do G53.

G40 is cutter compansation off.
linuxcnc.org/docs/2.6/html/gcode/gcode.html#sec:G40

More of a flying wing than airplane, but I feel ya.

That did the trick, I just don't have a clue why it started this.

Thanks for the assist.

always a good idea to start the G-code with a preamble set to Fusion360

G17 G21 G54 G90 G61 G40 G40 G80 ...

as You like to be set the mashine

S1000 not a bad idee to set a Speed as tools break with no turn

That preamble looks like a worthwhile thing to do.
Now, how do I add it to the post?
Went and had a look at the LinuxCNC post and was blown away, I changed a post for Vetric and thought that was a challenge, this Fusion post is way way above my pay grade.
Short of a copy this and paste it (here) sort of step by step is the best I could do.

Also, I was running a ngc file today with three different tools in it, when I get to the end of a tool run the machine stops (just as the code tells it to), it dosen't ask for the next tool or give an opportunity to go foreword with the new tool.
Am I doing something wrong? How do I move on?
My guess is the post is written in a way it will not allow for this.

I'll add a little bit of code to show the issue.

Thanks again.

the linuxcnc post processor of fusion does not use G53 at all
try to use the fanuc11m one
just to test

I'm puzzled about that double tool call myself, I have no idea what is going on there.
Something in the post maybe?

I put together a test file to add here, can anyone explain or point me in a direction to address this conundrum?

Thanks as always.
