Fusion 360 Mill Post Processor for Acorn with additional Features (New Version 5)

[swissi]

Looking at the output in more detail, all the moves look OK to me.

There are ten G94 (cancel Inverse Time) commands followed by a straight X move and I think they make it look a little jerky but they are just quick straight repositioning moves to go clean out the corners.

At this point I'll claim that everything looks perfectly fine unless somebody can provide proof otherwise

I turned the stock 180 degrees, then ran the 2D Adaptive followed by a 2D Pocket finishing operation. As I couldn't be bothered to shorten or replace the long stock, it was a little juddery during the heavier cuts but there was certainly nothing untoward and the result is pretty good.

I guess the rapid repositioning moves are the issue if there is one but apart from causing transient buttock tightening, it's not a problem.

I could probably risk a smaller cutter now and get a more precise result. Famous last words?

Again, it's some way short of a proper validation test as such but it seems to be doing the business from what I can see so far. Thanks for the excellent work and support, Swissi!

Thanks to Muzzer who found an undeclared Variable in the Beta_1 version of the Fusion 360 Post Processor with enhanced 4th Axis support that was posted here: viewtopic.php?f=60&t=2992&start=40#p36139

If you have downloaded the Beta_1 version, here's Beta_2 with the fixes. Please report any issues you find:

***Removed: Official version 3 now available on first post*****

As mentioned before, If you are currently using an earlier version of my Post Processor, please note that I had to move variable #300 to #330 and #301 to #331 so if you are using the mfunc6.mac file that displays all the File and Tool Information in CNC12, you have to modify these two variables or use the new mfunc6.mac file that's been attached to this Beta version.

Also note that this version of the post processor includes the support for Fusion 360 WCS and Geometry Probing but the output of the Post Processor need the CNC12 specific Probing Cycles that I have currently in Beta Testing.

Check out the draft version of the Fusion 360 Probing User Guide for CNC12 if you are interested in Fusion 360 Probing.

Version 3 of the Fusion 360 Post Processor for Centroid CNC12 is now officially released.

See the first post of this thread for the download link.

These are the new Features that have been added:

***Update: Version 3 of this Post Processor has been posted***
7/11/2020 MinRev-40783-swissi-003


***Change Log v3
New features added (click the links for Implementation Details):

• Improved Logic for Rotary Axis Support (less unwinding between Tool Paths)

• Property to Reset the Rotary Axis at the End of a Job without the need to unwind

• Property to Check/Update Tool Diameter Offsets in the CNC12 Tool Offset Library A Message like this is being displayed when a difference in Tool Diameter between the Fusion 360 and CNC12 Tool library is found:

• Support for Fusion 360 Probing (WCS and Geometry). Be aware that the Post Processor alone is not enough to enable Fusion 360 Probing. The Post Processor is just calling probing sub-programs that did not exist for CNC12 and I had to write them with big efforts. If you are interested in the Fusion 360 Probing Cycles for Centroid CNC12, contact me via PM or send email to swissi2000@gmail.com

***End of Change Log

Please report issues and suggestions for new features in this thread.

Great work Swissi, been using the previous beta without any problems. If I can get my library built in Fusion 360 (still figuring out DOC, IPM, SFM and feed per tooth that I should use on my PM25) version 3 should help keep me out of trouble. Maybe.

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,

from the error report it looks like you have some unsupported axes configuration/directions setup.

Have you tried another Post Processor? This problem might not be specific to this post processor and could be something Fusion just can't do.

Would you mind sharing your model in Fusion 360 so I can track down the issue?

I am 100% new to the CNC side of machining and 360. I'm sure it is just me and the way I think.

I have not tried the other Centroid PP with this part. I did with the internal spline part I made and there was an issue with the spindle starting which your version did not have. THX.

One side gets machined and then welded to another part. Then the second pocket gets machined in after welding. Like I said, I did find a work around and I'm sure there are other ways to do it too. I just thought flipping Z would post as it did simulate fine.

I tried to attach the 2 *.f3d files and they are not a supported format. "Invalid file extension: flange6 2x v1.f3d"
Should I email them to you?

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.
