I just plain need help here. Please don’t respond with “If you don’t know what you are doing then, don’t try it”, because nothing is more bothersome than someone telling me not to seek help.
Has anyone written a tutorial on using this break out board with an Arduino Uno R3? I know you guys are operating with a level of knowledge far above mine, but I’ve spent a day just trying to get the board to work with my controller and a stepper motor.
I’m suffering from the “Code is documentation” problem. It seems like anyone who has written something online about this is operating under the assumption that every reader is a programming guru. If anyone has the heart to write up a basic tutorial for wiring up a test rig, and show which calculations are important to get a motor turning then I promise I will share all my future developments with the community.
I’m hoping to use these chips to drive 3 stepper motors for a 3 Axis CNC machine, with the goal of having it up and running by April 2014. I’ve got a router up and running on GRBL with a CNC shield before. This is my attempt to get into the nitty gritty. Who knows months from now I could have a decent setup, but any help just getting started would be much appreciated.
No public wish lists :(
