Thanks for the advice guys. Mike, I didnt know you were on here. I'm Franklin Milton who contacted you about some of your servonut actuators that I got on ebay. Best deal ever, I got 8 THK actuatrs and 2 BE actuators for $300. Anyway, gloating aside, the teknic drives have been very straight forward for me and the documentation is great. Of course they wont give us ebay hunters any help we gave them no money.
