Thank you kwackers for sharing this project with all of us!
I have been reading this thread with great interest thinking it may well be the solution I was looking for my application. What I am seeking is a simple single axis controller for positioning a fence on various woodworking machines. The idea is to be able to simply input a distance with the keyboard and move the fence to that position with either a lead screw or timing belt drive. I'm hoping this controller could do this without too much difficulty simply by rewriting the code. Is this doable with this design? (or better yet, has anyone already done it??) I'm prepared to dust off my programming knowledge and tackle it if this is the right platform for the application I have in mind. Ideally other functions such as incremental positioning, preset values, etc. could be implemented also.
Any input or pointers would be welcome and if I can get this project started I'll start a new thread.
