the nema 23s on the techno will work do they have a model number, you will need to know what wire is what phase. sounds difficult it isn't!! look for model number we can get specs from that. i am a fan of the 201's and basically because i have a few and they are smooth!! gecko has a forum here on cnc zone and marris (gecko) responds to it, he can tell you better than i call gecko as well they are very helpfull! i have also used keling and john is pretty knowledgable as well
