I'm working on my first CNC build and I'm opting to build something like the OX. I want a heavy duty machine with a large work space. So far I have decided to start with the complicated stuff: motors, wiring and controller, and then move on to the actual building of the mill. This will be my summer project this year. I have opted to purchase the following parts to begin my project: Stepper Motors (qty4) http://www.ebay.com/itm/121146152794 He wasn't sure of the torq on these but thought they were around 175, I'm hoping they are powerful enough for my build 12V Regulated Power Supply http://www.ebay.com/itm/261198916470 same as in the OX build Arduino Uno R3 http://www.ebay.com/itm/251459710321 Arduino CNC Shield v 3.03 http://www.ebay.com/itm/271659685052 This looks like it should work well as a controller, however I'm not sure how to connect the 6wire stepper motors to the 4 pins on the controller. Pololu A4988 Motor Controllers w heatsink http://www.ebay.com/itm/191114673825 now hopefully I can get everything wired up without destroying anything! For the mill itself I'm using a: Dremel 8220 12v battery powered drill - (why battery powered you say!... well I'm also creating a 12v 1.5amp powered adapter so the dremel will run off 120v when connected to the CNC) http://www.amazon.com/gp/product/B0...&tag=wwwnathangood-20&linkId=ZQJULHW3NZJNXUPN Any advice on this would be great! I'm a noob and this is my first build but I'm also an electronics/computer guru so I'm looking forward to the challenge!
