Make a Rugged Stepper Driver
First part of my two part project to create a decent rugged stepper driver board is complete.
This is a simple, manually configured driver board that can do micro-stepping and can be made by a kitchen table constructor. It is not meant to be small and there are no surface mount components used in it's design.
Based on the Toshiba TB6560AHQ stepper driver IC it features 2.5A continuous and 3A peak drive with advanced current control features. Plenty for any model of RepRap.
The second part of this project is to convert the design to a SPI based programmable controller with step and direction signals that allows full 5D driving from a micro-controller with a limited pin count. (28Pin Arduino)
But first to build a few of the manual boards and evaluate them on my Huxley build.
