electronics for cnc router. Keling?

[svfrolic]

I will be building cnc router, r&p, 48 x 96 and I am researching for good electronic kit for the build.I will probably stay away from cheap ebay gear from China.
I came across that kit from Keling/Automation Technology:
NEMA34 1200 oz-in Stepper Motors 3 Axis CNC Kit (110VAC/220VAC): (3) KL-8070D Digital Driver, 24- 80VDC, 7.0A Bipolar Driver (3) NEMA34 -1200 oz-in Stepper Motors (1) KL-7220, 72V(No load), Max 20A,Unregulated Power Supply, 110VAC/220VAC (1) C10 Breakout board, E-Stop or Limit Switch can be wired, you can update to C11 or other board (1) 5V Power Supply for Breakout Board 110VAC/220VAC -
(not sure about inductance of these motors)
I would like to ask if anybody has experience with this kit.
Alternatively I could get NEMA 37 kit from CNC Router Parts (more expensive) or order electronics from Gecko.
I will appreciate all advice.

Do you know the RPM range of a 1200 oz stepper at 70V

Regardless of where you purchase your electronics, for a rack and pinion based system you will almost certainly want to drive the gantry with a motor on both sides. This helps avoid racking, and puts more power behind the largest moving mass on your system. So I'd make sure you're looking at 4 axis electronics kits.

I don't. I know only specs that I got from the vendor.

That's what I thought. I saw other people using four motor kit for r&p routers. It's just something that vendor recommended so I thought I would ask about these motors.
I was checking your website and I was going to send you an email asking about some components for my machine. I just need to make a drawing so I can explain better what I need. I plan to weld my machine from steel instead using extrusion but I would like to use some of the hardware you sell such as linear motion parts, motor mounts etc.
Now I am trying to figure out what would be good electronics kit for the machine.
