To: emc-users@lists.sourceforge.net Date: Sunday, September 22, 2013, 2:56 AM What did you set the drive steps and current to? Dont go more than 2000 to start with and then see if you need more resolution. OOh and dont use the Enable on the drive, it does not work :) -------------------- The motors are labeled 5.6 amps, no indication if that's peak or RMS so I set the drives to 7.8/5.6 peak/RMS. It's the only setting with either one exactly 5.6.
The lowest step setting on them is 400, which is half stepping these 200 step/rev motors. Didn't get any motion except random jerks until I set the drives to 400 and 200 in stepconf. Should I try a higher setting on the drive and leave it at 200 in stepconf? Belt reduction on the mill is 1.5:1 with 14 teeth on the motors and 21 on the ballscrew pulleys. Haven't counted the thread per inch on the screws, or if they're single or multiple lead. ------------------------------------------------------------------------------ LIMITED TIME SALE - Full Year of Microsoft Training For Just $49.99! 1,500+ hours of tutorials including VisualStudio 2012, Windows 8, SharePoint 2013, SQL 2012, MVC 4, more.
