Fusion360 has one for M3 and M4

93
Yep reboot the computer, that fixed it for me last time that happened, and can you post a gcode that failed

94
you can just do that in the air better to be safe then spending $20 000 for a new machine

95
Yes, when setting G28 to no then Fusion uses G54.  What I was still confused about was in Mach3...Under config...Fixtures - there's a screen where you can fill in values for G54 and save them.  But if my understanding is correct then I should just leave that area alone yes do that (don't save a G54)...And when I start a new part the work zero becomes the G54 for that particular project. only if you home first or know where home is

Also, when I close Mach3 I have been saying no if it asks if I want to save fixture changes. say yes

96
if you have a look at the post vids on the HSM youtube chanell, it makes it quite easy. have a look at the attached pick

You may have the stupid bug that makes Mach3 do a ghost offset, I call it a ghost as you can't find it and putting in the cancel tool offset codes clears it, Just type G40 and G49 into the MDI and hit enter.

Setting your home (machine zero) then going and setting the work zero sets the G54, G54 is the first offset if you don't set anything in fusion it just defaults to that if you home the machine and set the work zero.

The big problem with useing G54 at the end is if something is in the way you can hit it, useing G28 the Z axis goes up out of the way, then X and Y move.

It's easy to forget to set your clearances height high enough to clear everything in fusion, the bits of code i posted above is with the clearances height set to 15 mm.

One thing your need to do is read the manual for Mach3 it has almost all you need to know in it, this sort of thing comes up quite often here or on the fusion forum, And by hell there are some dangerous twats out there who will say you are wrong when your not,
(Not meaning you Wip your still seeking info, you know when you have one off those twats they lead by saying i have been programing computers for x amount of time )

Sticking the stock anywhere is what i do it's a big machine so most of the time to home the machine it moves in meters so I turn the home switches off and home in places.

Try putting the G40 and G49 in and try again to see if it comes good

This is the answer G28 G91 Z0. as rich said read what this means, I have never had fusion drag the cutter over the part as I set home before I do anything.

Start up rules to live by start the machine and clear the estop, home the machine after this whatever goes.

Wip what you have deleted you can change it in the post to not put out a G28 but do a G54

Start code with G28 set to No in the pre post diag

(T1  D=3. CR=0. - ZMIN=-4.25 - FLAT END MILL)
N10 G90 G94 G91.1 G40 G49 G17
N15 G21

(2D CONTOUR2)
N20 M5
N25 M9
N30 T1 M6
N35 S21000 M3
N40 G54
N45 M9

end code with G28 set to no

N46520 G0 Z15.

N46530 M9
N46535 X0. Y0.
N46540 M30

If you jump on the HSM forum you have a better chances at getting it fixed up fast https://forums.autodesk.com/t5/hsm-post-processor-forum/bd-p/218
