There are two vendors selling basic 6A stepper drivers on eBay.
One has a website http://www.electronicutopia.com and is selling them for under $25. Seems to be a basic full step driver with no isolation or heatsink. The other is user "esreng". His boards are about $47 but do half step and have a heatsink. I am looking for drivers to drive ~200oz/in steppers for my Shoptask 3-in-1. The Shoptask has a 2:1 ratio on the stepper drive and a 10 tpi lead screw so one full step would be 0.00025", which is more than the accuracy of my Acme lead screws, I think, so I don't think I need half step or microstep drivers. If anyone has any experience with these drivers or vendors or any other advice on these it would be most welcome. I am on a small budget so these are very tempting. thanks Alastair Addresses: FAQ: http://www.ktmarketing.com/faq.html FILES: http://groups.yahoo.com/group/CAD_CAM_EDM_DRO/files/ Post Messages: [EMAIL PROTECTED] Subscribe: [EMAIL PROTECTED] Unsubscribe: [EMAIL PROTECTED] List owner: [EMAIL PROTECTED], [EMAIL PROTECTED], [EMAIL PROTECTED] Moderator: [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] [Moderators] URL to this group: http://groups.yahoo.com/group/CAD_CAM_EDM_DRO OFF Topic POSTS: General Machining If you wish to post on unlimited OT subjects goto: aol://5863:126/rec.crafts.metalworking or go thru Google.com to reach it if you have trouble. http://www.metalworking.com/news_servers.html http://groups.yahoo.com/group/jobshophomeshop I consider this to be a sister site to the CCED group, as many of the same members are there, for OT subjects, that are not allowed on the CCED list.
