Help select Servo type, conversion from steppers.

Update:
Got the ESS Smooth stepper from Warp9. Connected it directly to my 2 existing BOB's. And after a few tries on the ethernet connection, it works.

So I'm up to 416,6666 steps/mm on the Z-drive and giving a speed of 12500mm/min
Y+1 slave axis, is 400 steps/mm and 18500 mm/min
X axis is 160steps/mm and 25000+ mm/min.

Most of the Z-axis resonance is gone, I guess there will always be some. But much lower noise.

Now is left to find the Acceleration/speed trade off.
Y axis (the worst one) is around 1200mm/s^2 I could set the rapid speed down, and increase the Acceleration.....

Further I need to figure out some 'issues' with the smoothe stepper, but that's a different thread.

Best Regards, Bo Andersen.

Great news.!! . . . Now buy some Lead shine EM806 Digital drives and take it to the next level. They are light years better than those drives you are using now.
Digital drives are SOOOOO much smoother than analog drives and run the motors much cooler and allow higher feed rates still.

With Digital drives and ESS you'll be able to run much higher Micro steps which give smoother running motors. Only way to appreciate the difference is to see it for your self.!
