I recently grew weary of messing with the mightyboard in my printer more than I was printing. Looked around for an alternative and really like the DuetWiFi. It then occurred to me that I already have the stuff to lash one up from parts. Well, sort of... No TCM2660 stepper drivers, but it looks like a properly set up DRV8825 stepstick will work as long as I don't try to adjust the current throuby Giark - Developers
