Does anyone have a post processor that works with the Revolution and Fusion 360. I use fusion for all my design work and don’t want to switch to a new software. 3 Axis machining is working fine with the elite masso post processor, but no luck with 4axis yet. I don’t mind editing the code, but see no need to reinvent the wheel if somone has this working already.
I use Fusion as well, but for now have no need for using a rotary.
When i did look into it, the only option was a ‘wrap’ feature available in 2D pocketing toolpaths, but that is limited to selecting a surface on a cylinder only to pocket. I believe this type of wrap is different than that offered by Vectric.
Fourth axis functionality, such as wanting to make a chess piece-like object, is now only available if a machining extension is purchased (on top of the subscription license).

I’ve used my usual fusion set up and milled on the rotary with Indexed milling.

Would you be willing to share that post processor file and a screenshot of your settings. I’m comfortable with CNC and been using a haas vf3 for some time. I’ve been at this for 8 hrs now with no luck
I have the multi-axis extension. However, I’m getting errors with the post processor trying to create the G-Code. Everything Fusion is telling me is that there is a problem with the post processsor file itself. I’ve had some success rewriting the PP, ie, I’m getting it to process and post, but it’s now returning incorrect cutting data…z axis cutting too deeply. I’m hoping someone has a working PP that will solve this.

It sounds like you are bringing a fair bit of experience to this already but have you tried Autodesk forum support for this? I have found the regular community members extremely helpful and quick to respond.

Not yet. I’m starting here and working my way from there. Since the machine is the common denominator, it seems the best place to start to me. I’ll look into the other forum as well. However, since the Onefinity is a niche market and not an industrial machine, this seems like the most likely source to find a solution, especially if others already have their machines working.

I use the PP generously produced by @blaghislain .

I just received my 4th axis add-on for an Original Series Woodworker. I am a long time Fusion user and I am looking for a good post processor. What is your experience with the blaghislain processor? I would like to run true 4-axis paths…not just index and mill.
I ended up just using a generic grbl post processor. Couldn’t get anything to work that was designed for the onefinity

You were able to get it to work? I tried the one included with the fusion library, but I keep getting the following error… Actually, I have get the same error using the Fusion Buildbotics 4-axis post processor.
Eventually, but I’m travelling at the moment. I’ll have to reference my library and get back to you.
I am just getting into this process now for my new Onefinity. I’ve done it before on an OpenBuilds machine. I think you need to make a machine config to add the A axis to the kinematics.
Make sure to turn off TCP as well. I have not tested this yet, so be careful if you do. Maybe run it with the 4th axis off the machine at first to be safe. I can follow up if it works (if I remember to). It does post, at least.

That kinematics layout worked well for me.
I ran into a few other issues that might be worth noting:
I am getting a weird line down my part, but I think the probe X-axis on my rotary is wrong by about 1.5mm. Cutting a hole from both sides of the stock shows a clear misalignment. I was able to fix this by adjusting the X offset for probing by a mm or so from where the manual says to put it, but I still get lines in my cut, so it might need more calibration.
I had one cut where the Y was clearly wrong after changing tools (about 2mm high). I think there was some dust on the tool setter and the height was set wrong on the tool change. The rotary is very sensitive to calibration errors as indexed cuts end up misaligned.
X offset is slightly wrong (line down part every 90 degrees):
