If all you want is a jog-dial then there are very cheap components available: http://uk.rs-online.com/web/search/searchBrowseAction.html?method=getProduct&R=6234221 <http://uk.rs-online.com/web/search/searchBrowseAction.html?method=getProduct&R=6234221>For example. I am not sure that the originally-posted magnetic encoder would be too suitable for a CNC shaft encoder, it seems too likely to suffer from bit-dither as it seems to measure the position of the magnet axis using hall effect deveices differentially, whereas a gray-code optical encoder should never change its output unless the shaft actually moves by a whole encoder-step. -- atp ------------------------------------------------------------------------------ Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensing option that enables unlimited royalty-free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
