This is my first post, but I think over the past many months I've read a majority of the posts here! What a great site full of info for us FNG/Greenhorns!!!
Anyway, I'm currently building a CNC router and have juts about finished gathering all my "stuff" to get it built. I am however having a brain freeze when it comes to power supplies. I need some help here.
I'm using Servos for all axis, here's the details I have.
X&Y Axis: Reliance E660's, 120V
Z Axis: Pittman 14xx, 38.0V
Using Rutex 990H drives.
So, I'm wondering, can it get by with one large power supply, or do I need 2 because of the differing power requirements of my servos?? What should the power supply rating be in Volts & AMPS?? I realize the rutex drives are only good to 100V and that should be more than plenty for the Reliance servos. They are rated at 10Amp max, and I have no idea what the pittman is rated at, but I think it's around 5 amps based on loose research.
I'm not intersted in building a power supply myself, so any pointers towards where to purchase one would be great....-or- if you're interested in building one for me, I have more money than time right now.
Any help would be MUCH appreciated.
Here's my basic design overview. My Moving Gantry Router is loosely based on the Data-Cut router plans, modified to my scrounging abilities, etc.. Will probably use Mach 2, still trying to decide on CAD/CAM software, leaning towards sheetcam for 2D work with TurboCAD, or Rhino, or Visual Mill, or.....
Have a happy new year,
