I am having trouble. Not sure but I think this has to do with me flipping Z axis in tool orientation as I am machining the underside of the part now.
I fixed this by changing the origin to the underside of the part and flipping it. I probably could of defined the part top as the bottom too but I didn't try that.
It just would of been nice to just flip Z in tool orientation and not mess with the drawing.
Geckocycles. I do a lot of two-sided machining with Fusion. For me, I would split "Flange6 2x" into at least two different machining setups. One for the top-side operations and another for the bottom-side operations. Specify the XYZ planes in the Setup. This will solve the issue and you shouldn't get the error. I always create two different Gcode files, one for the top and another for the bottom. Maybe this will help.
I didn't think about just doing 2 g codes. I remember seeing a Lars video where he put the origin in the middle (width) of the part too. Extrude 2 side from start of drawing.
When I flipped Z in tool orientation the simulator worked fine but just wouldn't create G Code so I was wondering why. I knew of some other work arounds after G Code generator didn't work.

Swissi,
I do quite a bit of machining with multiple WCS in one file, I would find it very useful to modify the "write tool list" function to list the tool offset info by WCS.
Code: Select all
(T1 D=0.5 ZMIN=-0.1755 - flat end mill - 0.5 Flat End Mill)
(T4 D=0.125 ZMIN=-0.3 - flat end mill)
N10 G90 G94 G17
N15 G20
Code: Select all
(G54 T1 D=0.5 ZMIN=-0.005 - flat end mill - 0.5 Flat End Mill)
(G54 T4 D=0.125 ZMIN=0.25 - 0.125 flat end mill)
(G55 T1 D=0.5 ZMIN=-0.55 - flat end mill - 0.5 Flat End Mill)
(G55 T4 D=0.125 ZMIN=-0.3 - 0.125 flat end mill)
N10 G90 G94 G17
N15 G20
Is this something others would find useful?

Clint,
tool offsets are independent of the WCS. I can see the benefits of listing all the WCS#'s being used in the job file like this
so you are aware that you need to set them all up but I don't see the benefit of knowing which tool is being used in which WCS.
Can you explain a little more why you need to know which tool is being used in each WCS?

I would use it as a reality check.
Here is a real example: I use G55 for the top of the part and engrave with T3 @ Z -0.0625 and G54 for the bottom of the part to cut out the part with T3 @ Z -0.005. In this example, it currently lists the minimum Z for T3 as Z -0.0625 and I have to search thru the Gcode for all instances of Z -0, make sure that it is in the G54 section, and that the minimum Z set to Z -0.005.
I use this as a double-check that I haven't told Fusion to do something stupid, which I have - way too many times...

Sorry Clint but I'm still struggling to understand the problem and I start to have the suspicions that you are using Fusion 360 in an "unconventional" way.
In the example you are describing to engrave on the top and on the bottom of the workpiece, this should be two different setups in Fusion 360 and you can use G54 on top of the workpiece for both setups and you have to establish WCS Z0 for G54 only once for the top as it will be the same for the bottom when you turn it around. In the top setup you set a engraving depth of Z -0.0625 and for the bottom at Z -0.005.
Everything will be handled by Fusion 360 and CNC12 without an issue.
Would you mind sharing the Fusion 360 model with me? You can email me the Share-Link to the email address in the signature of this post.
BTW are you using the CNC12 Tool Offset Library for your tools? I'm currently working on a new "ToolOffSetter" module for the ProbeApp that will take away the struggle many people have with Tool Height Offsets. I have to admit that it took me a long time to figure out all the details of all the different options available. The ToolOffSetter module does have a questionnaire about your machine, type of tool holders and what type of probes you have (even having no probe at all and touching off tools manually is an option) and will recommend and setup the appropriate method based on the answers. I hope to have it ready in November.

here is a weird one. I have a shared network folder for my router (think netshare) If I try to save the nc in the root folder it will not save. But if I have it in another folder in that share it will save no problem.

This looks like a permission problem that you are not allowed to save a file in the root folder of your netshare. Definitely not something I can help you with on the Post Processor side.

How many files in the root folder? I believe there is a limit of 254 files in the root.

2 files. This isn't really netshare. Just a shared folder on the computer.

Well this is this is even weirder. I was able to save no problem with Francos PP in the root folder.
