Hi David,
It's good to hear that the Duet gets better support for CNC.

After designing and building a CoreXY and two delta printers I decided to build a CNC machine. The two delta printers are controlled by a Duet Wifi. I am impressed by the power of the Duet. I just finished the build of the CNC machine and control it with a Duet Wifi. I use Fusion 360 as CAD/CAM software. Only one issue, there was no suitable postprocessor in Fusion 360 which could produce proper gcode for the Duet. After a little research on the internet I found that it is possible to change or make your own post processors for Fusion 360. So I did. I have now made, still a "beta version" version, a post processor for F360. Basic functions are working and did my first tests on the CNC machine. So far so good

The support of multiple WCS was also in the top of my wishlist, next to support for controlling the spindle. I have a Delta VFD007E21T controller in combination with a TeknoMotor ElectroSpindel C31/40-D-DBS-P-ER20-0.7KW-12.000-24.000RPM.

Is there a way on the forum to share the F360 post processor?
