Hello everyone, this is my first post here. This site has been a wealth of information and has helped me incredibly. I've been lurking for a while but am finally to a point with my CNC project that I need some help.
having finished my frame and xyz axis, I orders some stepper motors and a few kits for drivers. The drivers are:

The motors I am unable to find a spec sheet on. I purchased them from ebay and this is what it says on the label:
600089000B
1.8 DEG/STEP 3.3V 2.0A
NO. 03640
SHINANO KENSHI CO. LTD. JAPAN
I looked on google for that part number and also emailed the shinano company asking for details, but nothing as of yet.
They are bipolar motors (4-wire), and are pretty big (2.25 inches cubed, and about 1.25 lbs each). I can get forward and backward steps using the parallel port of the computer and one of the drivers with a 9v battery, so I think the wiring is correct.
My question is:
How much power will be needed to run all 3 drivers/motors? Should I use one powersupply and split it to all 3 drivers or should I use a seperate powersupply for each driver/motor?
Thanks,
