I am new to this forum. (ooh nooo!!) I need some help picking the right power supply for my CNC wood router.
My Setup:
I built this 3-axis router 6 feet long and about 1.5 feet wide.
Motors
3 Superior Electric Slo-Syn Stepper motors:
M092-FD09
300 oz/in
2.5v
4.6A
Drivers
3 MBL 536 Bilevel Drivers (Anaheim Automation)
Controller
I am using an embedded controller(uCsimm) that runs embedded linux (uClinux) to send the control signals to the stepper motor drivers. The embedded controller has an ethernet controller built in, so I have the machine in the garage and a 40 foot long ethernet cable that winds its way through my kitchen into a ethernet hub in my office. (I've tripped over this cable a couple times and almost crashed through a wall) . I've also designed a 2D CAD/CAM program using Visual C++. It works fairly good for my setup. All this frustrating work and you know what? I'm not wearing a dress just yet...
My current problem is the following: I was powering the drivers using a 28v switch mode supply and a 5v supply ( the ground of both supplies were tied together as well as the ground from my embedded controller) no filter capacitors. The machine has never runned smoothly, so I want to change over my power supply to a linear mode supply. I'm also looking at a higher voltage 50-70v for the power supply. Can one of you great lads tell me how to go about calculating the power requirement for my setup. I would appreciate it very much...
