Hi David, The four input wires are probably one for each of the three phases and one frame ground. (The three phases are usually connected together like a Y,...
Hi, I can only comment here on how I do it with my lathe as the miller is not yet CNC. I do a quick sketch in ACAD, scrap of paper or beer-mat. I then fill out...
Hi Les, What I said still stands where ever the tool post is located for the reasons I gave, that of the cutting forces. If you want to check with Boxford's...
Doug, I suppose their thinking was to try and get a new group of customers... By providing handwheels, they appeal to the people who have used nothing else. In...
Hello Charles, I believe this is a very common misconception... Actually, CNC is VERY helpful for one-off and short run stuff. In fact, a huge part of the...
Bill, I'd suggst a different approach... Since you already know Acad; use it. Ace converter will do a reasonable job of turning your geometry into gcode, and...
Ballendo, That is a selling point of CNC, but not what got me into it. Due to the tremendous setup investment (time and money) for a first time CNCer's one-off...
What you have are Brushless DC Servo Motors or sometimes referred to as AC servo motors. The Gecko drives are for Brushed servo motors. Brushless motors have...
Probably the best idea would be to combine both your ideas. Use 110v into the 220v input to get half the voltage, and go with Jons idea of running them out of...
Thanks ballendo, can you possibly tell me which apps to look for that work with Autocad for CNC work? Soecifically I can use some help maneuvering around the...
My sole intent when I first decided to CNC my machine was to be able to eliminate the Hand-Wheels. However... That has not happened yet. Even though their use...
... Fair enough. I have some 30V power suplies, but they're small enough that I'd probably want to use 1 supply per motor...hardly an ideal scenario. ... How...
Hi Ballendo: Good points all!! However, when I was just starting out, I had a Flashcut powered Sherline and I used a program called Drafix Cad to generate the...
... The 30 volt supplies will be ok for the motors, voltage wise, but a bit high for the 5 volt regulators, which would prefer about 8 to 12. ... Electrically...
... Yes, that is for a standard, permanent magnet brush DC motor. ... One wire is either a safety ground or a center tap on a wye winding. Most AC servo motors...
... Yup, I want to second this! The very first part I did when I got my 2-axis CNC system going was a part to mount the motor for the 3rd axis. But, now that...

Ok, so in summary, the options for getting up to speed are: Autocad, 3d transferred to a CAM program such as VisualMill Ace Converter or similar g&m codes...
The cross sectional area of the core is the limiting factor as to how mush flux at saturation the xfmr can handle. The "core" is only the bit in the center...
