I'm very thankfull for your reply,however I must warn you of my lack of knowledge in regards to stepper motors...zilch!!! The info does not tell me the colour use i.e direction-step and motor connections,I don't know if I would end up destroying the boards if I use the 'try it anyway'. techique, The diagrams supplied for the controller boards do not state the colour , only.. direction-step-2b,2a-1b,1a so I am at a lost which goes where. My intentions for these motors is to construct a router for helping me in my hobby of aircraft modelling cutting woods of upto 1/4" thick. I will appreciate any help to this end.chaz@2b
