High current bipolar stepper drive

@Xerxes: Not a problem. And it's not a paste. It has a consistence like water, more fluid than the antifreeze coolant mix you use in your car. Just shake it a bit before use.

BTW: Picture of the tip now in my gallery: http://www.cnczone.com/gallery/data/.../soldertip.jpg

I would be very interested in both the description of the workings of that drive circuit and the current sense circuit you mentioned.

Hey guys, just a pic of the progress. If anybody wants the eagle files, just let me know. I'm considering bringing all important pins out to .1" headers just for software development and testing because I've got to get a board ordered in the next few days and I havent settled on pin assignments. Any feedback or input is welcomed. Again if you want the eagle files just let me know and I'll zip and post them.

Hi guys!
Does anybody has the L6506 block for EAGLE 4.13 ?Or where to get it?
Thanks a lot!

Just curious if this project was finished. Did it work as expected?
