I made a video to plug the spindle I bought. I made the schematic and did the PCB layout in Diptrace (www.diptrace.com
) then exported as a DXF. I used VCarve to generate the paths etc, then Mach3 to run the router.
Here's the kicker - the endmill I used is 0.005" diameter! Got that from Think & Tinker at www.thinktink.com
