Impressive video. Interesting how you set the angle precisely. The thought that went into building that attachment is also pretty cool. So for LinuxCNC, if you have the A Axis and an encoder on the horizontal spindle, how do you tell the system to hob the gear? Just curious. Nowhere near being able to do this yet. Don't even have my Harmonic Drive operational nor an encoder on the spindle. And my mill has the rotatable X axis but no horizontal feature. You mentioned the program you wrote so you can derive the numbers. But ultimately what does the G-Code look like for hobbing that gear? Is there a feature in the G-code for LinuxCNC that lets you slave the A axis to the Spindle with a specific ratio? Sorry for the ignorant questions. Don't even know what to google to get these answers. As in I don't know what I don't know.
