      I'm looking for an affordable CNC 4-axis conversion package to convert
      a stepper CNC router to servo motor driven. Brushless nema 23 servo
      motors with encoders and control box ready to hook up. Any leads
      would be appreciated.

          shipment and they replaced it with no compalints.

                Hi

                These servodrives accept pulse signals for step and
                direction from the parallel port and have been tested
                for problem free operation with Mach.
                We can have full control of the drives from the Mach.
                High speed, high accuracy, closed loop operation are
                the advantages of these servo sets in comparison with
                stepper motors.
                These servos are high torque 400W to 6000W. It is not
                the cheapest solution but be sure that it is the best
                solution.
                All come prewired and preconfigured to work with
                Mach3. You can not compare them with low-end servo
                motors and drives which can read up to 1000steps/rev,
                have not got build-in encoders and have up to 120ozin
                torque. In fact 120ozin is not enough for CNC
                machining. We use at least 4 times this torque for CNC
                machining.
                If you use belt to multiply the torque you will have a
                percentage of power loss and you will decrease the
                speed of your axis very much. So, the best solution is
                for you to determine first, what is the torque you
                need.
                We can do it with many ways. You may already know the
                way but I will say it once more: Hang up a weight from
                the outter diameter of your handwheel. You ll start
                from a light one and add weight each time until the
                axis move. When you see motion then you will have
                torque(able to move axis)= radius x weight.
                After this test you will know what torque you need.

                The servo motors I tell you about, have from 180ozin
                (13.2kgcm) up to 4500ozin torque, 10.000 steps per rev
                and do not need an external DC supplier to work. They
                are plug and play. You will also see couplings which
                allow you to connect the shaft of the motor with the
                shaft of your axis.

                Take a look at:

                  Sadly "Affordable" and "brushless servo" cannot usually be used in the
                  same sentence! Well I guess it depends on how rich you are of course ;)

                  Unless you can find matching drives and Servo's on ebay etc. Brushed
                  servos are by far more affordable.

                  I have tended to stick with Brushed drives/servos and no problems
                  really, at least you can mix and match drives (Gecko, Rutex, Teknix etc)
                  with more or less any Brushed Servo motor without the hassles Brushless
                  can give you.

                    The machine I'm converting to servos is a Techno isel model 27 built
                    in the mid 90's. I bought the system without any software and
                    converted it to run on Mach2 then Mach3. I'm very familiar with the
                    Yaskawa motors because I program and maintain large CNC routers in my
                    day job, which use Yaskawa and fanuc motors. The Mach software is
                    similar to fanuc in its programming language and I want to continue
                    using it. The conversion kit from techno runs around $4000.00, for a
                    4-axis control. It seems that a system from camtronics would be
                    approximately half the price. But as with everything in life I don't
                    want to buy a system just because its cheaper and I would like more
                    leads to comparable systems and your experience with them. Thanks
                    for your suggestions so far.
