    Hi all, I’ve been lurking on these forums for a couple weeks now gleaning lots of tips as I try and build my MPCNC, but now I’m stumped and need to come out of the shadows and ask y’all for some help. So I bought the parts kit from Ryan and everything has gone really well so far, but I’m at the point where I’m supposed to adjust the driver voltages. Or am I? Is that something Ryan already did? I hope so, because I watched the Pololu video and I’m still pretty lost. I understand how to take the measurements, but I have no idea what voltage and amperage I am shooting for and those formulas make my head hurt. Thanks for any help and looking forward to seeing you all around the forums.

    – Jeff

    Already done! Plug it in and get it dirty.

    Awesome, thank you! And just for future reference, what voltage do you set these at? You know, just in case I ever actually need to do it for some reason.
