1.7V 4.7A Stepper motor which driver

[motorsports]

I am building a Flying gantry CNC Router, with 2 motors and leadscrews for the Y-Axis. 27" X 36"

I just bought 4 Superior Slo-sync motors (used) and their rating is as follows:

1.7V
4.7A
150oz*in holding torque

My next step is to buy a controller for these motors, but it seems their isn't much out there for the higher current controllers. I will need at least 10A/channel because the Y-Axis drive will have two motors connected in Parrallel.

First question is do you know of a good board that will run these motors?

Second Question: What will I need for a power supply? (Volts, Amp requirements)

Third Question: Am I better off buying a good board, and then buying motors to suit it.

Em ...
not to be negative, but you need a single driver for each stepper.
So you need 2 drivers for the y, and the controller sw (like mach3) is told to drive them together i.e. slaved.
There have been many threads / comments;
You cannot make 1 driver drive 2 steppers well.

Ok hanermo, Thanks

I had read a thread where someone was told they could run the two motors in Parallel, but they would have to remember to double the current capacity for that drive.

I will go for a board with fourth axis capability then.

Actually, a member here has designed a 5amp board that will actually "slave" the two motors in hardware. It's a 4 axis board, but two of the axis' can be driven from a single input.

As was mentioned, you don't want to run two motors from one drive. You could also use Gecko's to drive those.

However, 150oz is on the low side - you may want to go with something bigger.

For $335, you can get four 305oz motors and a 4 axis driver from HobbyCNC.

It also includes everything you need for the power supply except a 24V transformer and a case to hold everything.
