Hello! I have been dreaming of building a CNC machine for quite some time now. Today is the day that I actually am going to start putting money on the table and ordering some parts to put this thing together!!
Basically I am building a small machine for metal work. Travel will be about 1.5' x 1.5' x 1'. My goal is to use Servo motors, as long as things don't get too complicated or expensive.
Here's where I am starting out..
I am interested in using mach3 software.
I have found some boards on ebay that seem to be quite well priced, and are labled DDCM3V5.0. They seem to be a board from China, but I am not quite sure what exactly they can do. Do they act as both the breakout board (pc interface) and the servo motor driver in one device? Or would I still need servo driver boards attached to this? Does the encoder feedback from the servo connect to this board somewhere, or would this feedback be a connection on an additional motor driver board?
If these boards are not fit for servo CNC, can anyone suggest a good starting point for a breakout board / driver / servo combo for me to look at ? I really would just like a good recommendation for a cost efficient driver / breakout board combo for servos / encoders etc.
Goal would be 0.001" precision. Speed does not need to be extremely fast, but is a bonus of course. The spindle router will most likely be in the range of 5 - 10 pounds, 10 000 RPM.
Thanks!
