Hi all,
Just brought a King Rich 3000 and have started to convert it to CNC. I am a bit late starting the thread as I have already set up the X & Y axis. To help keep costs down I have done a couple of things different.
For example I am using 400w servo's instead of the 750 normally used. My thinking was that the ProTac guys would have used bigger motors then needed also I figured I could reduce the gearing if needed. Standard pullies are M3 15mm wide belts with 16 tooth driving 44 tooth giving 2.75 reduction. To my surprised with a bit of reconfiguring the drives I got it to work. The big surprise is that I am getting travel speeds of 4,000mm per min. Have even got it going at 5,000 but decided to back it down.
The servo gear I used have a lot of advatges because the software behaves as if it has steppers on the end of it but they are servos.
Here is a link to the supplier,
Single Axis 400W Brushless AC Servo Kit :: Servo Kits :: CNC :: Ocean Controls
Each axis cost me the same as a motor only from other suppliers.
Thats enough for now,
Have a great day.
Tony
