Re: [CAD_CAM_EDM_DRO] Linear glass scales...dro

Hi,

I have these scales made in India and marketed here in Britain by Liberty
Systems Ltd., they are 5 micron but I saw on the website they did many
different resolutions.

I have the manual somewhere with the manufacturers web address on it, when I
find it I'll post the url.

They might deal direct.

Regards,

Terry
