Ok, I'm building a moving gantry style cnc about 4'x4'. My problem is I don't know what reduction I need on the x axis. The gantry is going to weigh about 100-120lb. I'm using the g540 even through I know it could be a little small for the size of motor I might need to move this at a reasonable speed. Already bought the kehling 387oz and am planning on overcoming the small motor size by utilizing the 4th driver and running two motors on the x axis. I believe that would give it more power and not sacrifice speed. So what is confusing me is I'm thinking I need to have some kind of reduction for this but the 2000 step think is not making since. If I actually had 2000 steps I wouldn't need any reduction? 1.19in pulley*3.14= 3.7366/2000=.0018683 is close to 1/512 of an inch? Thats better than it would ever need to be for what I'm doing. wood, plastic and aluminum. Do I still think of it as 200 steps? How much do I reduce it? I know someone on here has the answer.
