Re: [CAD_CAM_EDM_DRO] Re: Rong Fu 31 CNC Conversion Kit / Instructions / Help? :D

Hey guys,
Yep, planned on using ballscrews for x / y. They're
just too sloppy for planning on making holes that do
not look like eggs. Fine for manual straight lines
but I realize it'd be a bear on cnc.

This is one of those things I wish I had a cnc mill to
make the conversion.... lol ;-) and also thanks for
the pics on your site Bubba.... I've got to go get my
3 ph hooked to my mill/drill today and take
measurements for acceptable ballscrews so I can start
watching ebay.
