Stepper problem

Hello :) Yes I am sure, I followed his instructions to the letter... I read carefully wiring diagrams from CNC4YOU and from the AM882 manual. I have checked several times.. I should try to plug my Mom's computer to see if the problem is not just the computer --'

I haven't tested the drives / motors the way you mention. How do you do that ? Drivers are brand new, they seem to work fine (they hold the motors in place when the Mach3 reset button is "up" and let them turn freely without power when it is "down").

@noplace
That, my dear, is a great idea, it's probably the only thing I haven't tried. I happen to have a PC power supply laying somewhere in my room.
