If you are going to have EMC do tapping or threading, you may want to have the frequency on the upper end for better speed control at low spindle speeds. I assume you have the C11 pot turned all the way up to get 5 Volts at 200 RPM? Are you using an EMC axis or spindle feature for control? If it's convenient, would you put your .ini and .hal files on your website and post a link? -- Kirk Wallace (California, USA http://www.wallacecompany.com/machine_shop/ Hardinge HNC lathe, Bridgeport mill conversion, doing XY now, Zubal lathe conversion pending) ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
