Thanks Sam. I believe my motors have a common on two pairs of coils. I think like this: 1 C 2 | | | WW WW MM MM | | | 3 C 4 I don't know the options for wiring this configuration, but the Gecko documentation indicates that you can series or parallel the coils for a four wire configuration. I get the feeling that currently, my four coils are driven separately. The plan so far, is to just reproduce the present wave forms, so I won't need to know what I am doing. I'll just look like it. -- Kirk Wallace (California, USA http://www.wallacecompany.com/machine_shop/ Hardinge HNC lathe, Bridgeport mill conversion, doing XY now, Zubal lathe conversion pending Craftsman AA 109 restoration Shizuoka ST-N/Bandit CNC) ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
