My 4 axis setup continued…

So I fixed the post processor for autodesk fusion 360, which was very easy. Their forum has some posts explaining what to do. The rotating axis is fixed to the A axis in the produced gcode, so i needed to remap my axes because until now i have had the A axis as slave to X. Now my slave is B so A can become the rotating axis.

Then in autodesk fusion 360 i loaded a part i designed some time ago having features on several sides. I recreated the cam operations and set the tool position per operation. Generated code and voila. Next i loaded and ran the job without tool inserted and with some random scrap for stock. I also set a high z zero position for this test run.

In this video you see at 26 th second that it turns automatically to 270 degrees for the next operation.

Next I want to machine the part for real. The size will be irregular in z as it rotates, so I need to find a smart way to fix it in the chuck and still maintain correct centering.

My cnc has two drive screws for x axis. One on each side of the gantry. I use x and now b to drive the two motors in sync.

What do you edit after generating. Are you using ADF360. ?

Super to see your progress.

@brian_alley that is also a possible way. The exact configuration depend on many factors. I wanted a gantry that would self align when calling home on x. Each side will fine-home individually.
