hello people

looking at building a mini wood/plastic router/engraver but the problem i have is i have 4 stepper motors

3 Sanyo Denki unipolor but only know they are 1.3Ω which i have no idea on what it relates to and 1.8 deg/step

1 Kyushu Matsushi.ta rated at 6v, COIL 8Ω, deg/step 1.8

what i am wondering is what voltage i would be good enought to run these motors at and the best user built board to build that would not cost to much to build

anyway hope someone out there can help me
Cheers
William
