Fusion 360 - EMC Post ?

I'm trying to learn Fusion 360. I have a start on this but am by no means competent. I've tried to post a small part to G-code using the LinuxCNC (EMC) post processor. On a tool change I get this command:

G43 Z0.06 H1

or similar. There is a modal G0 above this which applies to the Z move? I've been too scared to try in on the machine. Would this command even work, with the Z0.06 embedded? When will the Z0.06 move happen, before or after the tool length comp? The Z0.06 moves to clearance height over the part, so the intent is to apply G43 first. Very confusion, or I'm missing something.

I spent a day leaning enough about the Fusion Post to hack a change to this. Even if this command works it's confusing to me. On my post the G43 is on a line above the Z move.

Does anyone know of a "better" LinuxCNC post for Fusion 360 milling? How is their Post for LinuxCNC turning?

Thank you for any insight.

You might need to include a little more of the gcode before, including and after the tool change.  I'm struggling to picture what you are referring to.
I use a copy of the standard linuxcnc postprocessor in Fusion360 on my mill.

Sorry. I was mostly interested in that particular command line. But some more context would have been good.

This is a test part with a simple circular pocket (1/2" end mill) with a chamfer around it's top (1/2" spot drill). I don't think it'll matter much to the code, but I selected Autodesk's Generic 3D milling machine. For a post I used the EMC2 milling post from the Autodesk library. There is another post, just EMC, which I didn't try.

The program preamble and first tool change are as:

(POST-TEST-STOCK)
(MACHINE)
(  VENDOR AUTODESK)
(  DESCRIPTION GENERIC 3-AXIS)
(T1  D=0.5 CR=0. - ZMIN=-0.5 - FLAT END MILL)
(T20  D=0.5 CR=0. TAPER=90DEG - ZMIN=-0.2 - COUNTERSINK)
G90 G94 G17 G91.1
G20
G53 G0 Z0.
(2D POCKET2)
T1 M6
S7639 M3
G54
M8
G0 X0.465 Y-0.0681
G43 Z0.6 H1
G0 Z0.2
G1 Z0.15 F126.06
S7640
X0.4654 Y-0.0669 Z0.1391

It's not executing G43 then Z0.6 then H1. G43 requires the corresponding H1 offset to be specified on the same line and will apply it to the Z0.6 move if you specify it on the same line. You could instead write G43 H1 on one line, then the Z0.6 on a subsequent line.

Short answer is yes, the H1 offset will be applied to the Z0.6. 

You should get a copy of one of Peter Smid's books which explain the common G and M codes and show how they should be used. I prefer "CNC Control Setup for Milling and Turning" although the more commonly referred to one is "CNC Programming Handbook (3rd Edition)". Other references are available online but Smid's books are a good place to start.

Muzzer:

I think of G43 H1 as one command. I'm surprised the Z0.6 intermixed is OK. Sounds like it follows the rules though. I studied the LinuxCNC documentation and it didn't answer either question.

I hacked my Post to output two lines which is much easier for me to read:
G43 H1
Z0.06

I thought I had a book by Smid but don't now see it on the shelf. Must have lost it during the last move. The LinuxCNC documents and forum have answered all my questions until this came up.

Thank you for the insight.

The Z in the middle of G43 is wierd. But it works, I use that post all the time.
