Splitting by Tool Results in Unit Change

MR-1
1

Using Fusion. When posting each tool individually, results are as-expected (output in inches) and includes G20 (unit in inches) in each file.

When posting the whole setup or multiple tools (and selecting split by tool in post processor settings), the post doesn’t include the G20 in anything other than the first tool file & thus, CutControl imports everything after the first tool file as metric and all the moves are much smaller than what they should be.

Anyone else experiencing this?

Example of the first tool header, which includes the proper codes:
(1001)
G90 G94
G17
G20
(Adaptive1)
T70
S8000 M3
G54
M8
G0 X-0.1154 Y0.0479

X0.1103 Y0.0582 Z0.0825 I-0.0058 J0.1246

X0.1208 Y0.0289 Z0.0561 I0.0252 J0.1217

Example of the second tool file, which does not include much of the first tool’s header info:
(1001)
(2D Chamfer1)
T35

I’m sure this is just a post processor modification, but I can’t imagine I’m the only one with the issue.

The work around is to post all individually, but when the “split by tool” function works, it’s convenient.

Known issue with GRBL. You can’t do tool change g code, “T”. Post it by each tool or change controllers.

Fusion outputs separate files per tool. This isn’t a controller issue in this case; rather a post processor issue. Manually inputting G20 to the start of the files works properly in CutControl.

I imagine the PP could be edited to make this happen, but I’ve been too lazy to read through it and see what lines need added or edited.
Until they introduce multi-tool programs and auto touch off I’m not too worried about it. I’ll just post separately and do the multi-program thing.
The one time I tried posting like this I manually added the G17 G20 etc to make it run properly.

Whoops read this completely wrong.

If you put in the following in at line 450 like below I believe it will work. I can’t test this because I am not paying for F360 right now but this should be it. Let me know if it doesn’t add the G20/G21 at the beginning. FYI you can copy it from line 426.

Tried that already but no improvement. I believe further up there is logic along the lines of “first sequence” which then skips where I had added that section. I’ll look again.
