This is a 6" rotary table with CNC attachment for use in the Bridgemill, Shopmaster and Shoptask machines equipped with the Gecko 540 drive. It has a 400 OZ/IN stepper motor cabled to plug into the Gecko. For those with a different driver, you could change the cable end to match your CNC. The unit will be delivered in 2 boxes, with the CNC kit separate for safer shipping. Installation is strictly a bolt up operation taking a few minutes. The kit allows you to retain full manual functions of the rotary table as well.
