Guess I lost my first reply somehow - Dazp1976 you are exactly correct. I found Auto Tech., during my frustration period a couple weeks ago during the "China Syndrome" debacle in shipping. My purchase was based on a recommendation and I sorely regret it. I'm completing a machine that will be open source and I ordered a 439 oz.in. kit from China (NEMA 24) to save a few bucks. Big mistake and will never be repeated. Frankly, they have blatantly lied to me over the course of almost 2 months - stopping me in my tracks from moving forward....lesson learned. Would attach a photo of the prototype but can't seem the find the attach button...
