Need Help Configuring 4th Axis (C-Axis) on 3-Axis CNC Router in Fusion 360

[jose43714]

Hi everyone,I have a 3-axis CNC router and recently purchased a 4th axis (C-axis) add-on for it. For context, I've attached a video showing the setup. From what I understand, this C-axis can only move the Z-axis position, while the angle is adjusted manually.

I'm struggling to figure out how to properly configure this C-axis in Fusion 360. Specifically, I need guidance on which post-processor to use for this type of device. If anyone in the community can recommend a suitable post-processor or share an example of how to configure this type of cutting tool setup, I’d greatly appreciate it!
Thanks in advance for any help or suggestions.

Hi @jose43714 ,

You can set up the machine definition here by adding rotary axis and entering the correct orientation vectors for each position. This ensures the tool aligns properly with its default (C0) position. For example, if the tool’s C0 position points from the origin along the positive X-axis, set the “head” vector to match that direction, as shown in the screenshot below.

To generate NC code, you can use a generic post processor like Fanuc, provided it matches your machine’s NC code. Alternatively, you can select a suitable post processor from the post processor library.

Thanks,
