My CNC router made some real progress today. For about 4 hours, I struggled to get an EDE1204 Bi-poler Stepper driver IC working. I finally gave up and decided to write a program for the Parallax Propeller to drive the stepper. Five minutes later, I had a working X axis. Its bad enough that I wasted 4 hours, but those stupid ICs (I bought 4 of them) were $9 each.
