Hello, I'm new to the group and cnc thanks in advance for any help! I recently bought a taig mill with sherline steppers, denvercnc control and running Mach2 controller on winXP home 2400Mhz dell computer. I'm having problems with what I believe is interference from the spindle motor or general A/C noise. If I leave the mill spindle running and have Mach2 doing nothing (holding the steppers at 0,0,0 and wait about 2 minutes and then check my handwheel zeros the steppers will have moved .002 to .035 (or more). Mach2 still says 0,0,0. I can observe the servos "glitching" randomly, but they always seem to move in one direction. If I switch the mill motor on and off or switch my Sherline lathe motor on and off nearby 90% of the time one or more steppers will glitch. I tried running power from a different circuit down to the motor (extension cord) this seemed to help a little (or maybe wishfull thinking?) but the problem is still there. Yesterday I mounted a sherline motor/head/speed control on the mill and the problem got worse. It's there with the Taig or Sherline motor though. Should I try grounding my mill? Should I ground mill, controller, computer all to the same point? Thanks for any suggestions, Andy 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.
