Re: [CAD_CAM_EDM_DRO] Re: Proxxon Mill CNC Conversion

Graham - Those photos are impressive. Nice work.

Thanks for the input. The Proxon does seem a bit small for my needs.
At this point, I think I will get the Taig as it appears to fit my
needs the best, albeit expensive.

Thanks again to everyone for the input. I'll post some pics when I get
it running.
