[Emc-users] EMC2 and 4th axis in milling: specifying speed and angular velocity?

2010-12-08 Thread Igor Chudov
I am not too far from adding a 4th axis to my Bridgeport Interact mill. The 4th axis will be a servo driven rotary table that sits vertically on the milling table, so that the axis of the rotary ta ble is parallel to X. I have a question, inspired by a recent discussion. Let's say I wanted to

Stephen, thanks, this is a wonderful way to implement this! i -- What happens now with your Lotus Notes apps - do you make another costly upgrade, or settle for being marooned without product support? Time to move off
