Re: For Sale or trade (4) bipolar Step-Syn stepper motors

I thought that I had 4 bipolar motors but I have 2 bipolar and 2
unipolar. I am going to go and get 2 more printers today. They have
one of each in them. I took the case off of the back of each type of
motor and the bipolar do not have the center tap. I will still end up
with 4 bipolar motors that I don't need and want to sell.

I am planning on using the Hobby CNC driver board. I believe that I
can drive the motors with 12V.
