I'm wondering if anyone have installed spindle speed control on their Sherline mill. I've tried to find information on this with Google, but there isn't too much relevant info to find it seems. (I might use the wrong search term though)

I'm hoping to control the spindle speed from EMC, and I guess it shouldn't be that difficult compared to some of the achievements shown on this forum...

The closest thing I've found is the DigiSpeed from Homann Designs, but no pictures of a install on a Sherline or user feedback.

Regards,
Ronny
