Hi Guys

New to this excellent forum, Just prurchase the MDF and will be starting cutting it up today.

On the motor end Biplor and unipolar what is best.
I have the chance of getting a:

VEXTA STEPPER MOTOR PART No PK266-02B DC 2A 1.8 OHM . 2 PHASE STEPPER MOTOR. DOUBLE SHAFT TYPE. 56.4MM SQUARE. 1/4" SHAFT.

It is new and is cheap, is two phase bipolar ?

On Cranky's web site hes says to look out for brands like Vexta so I thought this would be suitable.

Do all the three motors have to be identical ? I know they all would have to be either biplor or unipolar but thats all.

Thanks guys
