Ok, thanks Hood, will have a look in the file.

I have fixed the USB issue too - get rid of the hub and just run two extensions back to the PC, works fine now.

What do i do with it?

I'm still new to Fusion, and is it ok with Mach3??

Just spotted another possible error -

in the first segment - the one that works, the code rapids to X & Y then drops the Z

In the second segment - the crap one, the code drops the Z then rapids to X & Y - just right to make a nonsense out of the clearance plane and mach into your clamps and fixtures

I have posted it on the Fusion forum, I cant see anything that can be edited in the post - it seems tool-specific for some reason it does not like my spot drill anymore but did a day or so ago

Pisses me off because it a was a new tool too.

Air-cutting probably would not show much as the error was only about 15mm - difficult to see with not toolholder mounted.

After a tool change you should not have any Z movements until you have called the tool height offset.
Not sure whether it matters if there is a Z call on the G43H line  but my BobCAD post puts a move there and there are no probs, for example
N01 T75 M6
S1400 M3
G0 G90 G54 X26.678 Y24.157
G43 H75 Z25.4 M8
Z5.08

That is exactly what my meagre G-code knowledge is telling me too, but Fusion has other ideas and I have less tools now

Its odd, i have other code that uses the same tool and it works ok, i have messed with just about all the settings in this part and just cant make it get that line correct.

So your'e saying all the other code is wrong and this one is right, but backwards?

All the posted code i have has G43 Zxx Hxx format and works ok, this one has the Z before the G43 so must be wrong?

Just read through a much larger job i did yesterday and the G43 line is ALWAYS G43 Z30.0 Hxx

SO something is upsetting the post it seems.??

This might help, its the raw code, first op works, second op fails. The placing and format of the G43 seems wrong in 2nd op??

Ok, so yesterday i had a great run on the mill, one part, 6 tool changes, perfect result.

Tonight was a simple part - face, spot, drill 3 holes.

So, I set the ref's with my Haimer, the face cut works nicely, good finish, requests the spotting drill, drill fitted, Z drops to below the vice and then proceeds to snap my nice new bit off by ramming it into the back of said vise Much language and head scratching follows. I did hit the big red button but was too late to save the bit.

Ok, new bit fitted, ref'd the machine again, reset my co-ordinates, run the part again, facing cut took nothing off of course, just a whisper, spot drill requested again, fitted, this time i had my fist over the stop button, watched and yes it drops the Z way too low for the tool, stop pressed, give up for the night.

Now, had a glass of wine with me tea, and looking at the code (fusion 360 CAM) I see it is asking for a Z30 move BEFORE applying the tool offset !

Surely that is a crap error - the previous tool was shorter than the spot drill and the height it was heading for was correct for that tool of course but put the longer spot drill in and - snap.

Just so i know where to head, is this a Fusion 360CAM error, post error or just me being a twat ( I doubt it this time though )

Surely it MUST apply tool offset before commanding ANY Z axis move?
