Setting spindle position


Premium Member
There's been a discussion on the LinuxCNC group about positioning the spindle for an automatic tool changer. I think for one of those spindles that has the two tangs on the tool.

Now I don't need that but I can see there might be a time where a boring tool might want to be put into the tool changer in a certain orientation so it doesn't bump up against other things. The end result of the thread was a simple M66 command and looking for a spindle point. It's not super precise but pretty darn good.

I made a shaky video (25 seconds) with my cell phone which is all over the place so it doesn't look like it lines up but it really does each time. If someone wants I'll do a better video with my D800 on a tripod.
