Re: Create A axis from HV6

Thanks Paul just what I was looking for. In fact, before I acquired
the HV-6, I just a missed a rotary table like the one you converted on
Ebay.

I also was inspired by the other projects on your website.

Question: I had also thought of making an off-line divider controller
like you made. I was going to use a PIC. Is the design of yours
available? No point in re-inventing a wheel with so many projects to
tackle. ;-)

Thanks for your help.

Regards

David
