Maybe a kit with instructions and parts.

Would seem worth exploring as motor drivers.

The response from the group was instantaneous.

I am wondering if anyone has had luck in using DS motor / Meade control on a large Dob base. I am starting to build a 13" f/4.5 Mon, 09 Nov 2009 19:58:50 GMT pinyachta http://tech.groups.yahoo.com/group/RoboScope/message/12114 http://tech.groups.yahoo.com/group/RoboScope/message/12114 Must have used google to translate. Maybe I should offer to clean it up in return for one of their "self-assembling kits." Geo.

Have you ever had the chance to try one of the new 497EP's against this code?
