No, I haven't included any electronics information, being that this is a low cost design I figured people would be trying to keep it cheap and would go with a 24v power supply, a cheap controller board off ebay and 278oz or 425oz motors with 1/2 Acme 10/1, 10/2 or 10/5 screws.
Most of what I am using is recycled from previous machines so I have mainly older driver boards, Xylotex and Rockcliff (A3977 based), and SOC Robotics MK4/MM160 (TB6560 Based) with 24v power supplies, motors that range between 218oz and 425oz and 1/2 ACME screws with various tpi/starts(10/1, 8/2, 10/5). On the 2 prototype machines I made I used 218 oz motors with 10/1 screws on the flying gantry design and got 36 ipm, on the moving table I wasn't exactly sure what I needed so I went with 425oz motors and 10/5 screws and my rapids can be up to 270 ipm (I don't run this fast) but I really haven't spent a lot of time trying to fine tune it yet.
There are a lot people here with a lot more knowledge about matching drive systems to machine design, anyone want to give a recommendation on a more recent driver setup and motors?
