Hi all,

Just thought I'd share with you all my success that I had last night. I've designed a micro-stepping controller based on a PIC microcontroller called PICStep. It is capable of driving 3Amp per phase @ 54V and supports all modes up to 1/8th stepping.

Well last night I did the final testing of the driver and it all worked perfectly! I got a cheesy 0.75A motor up and spinning to a few hundred RPM and then to about 500-1000 RPM via TurboCNC running at 16KHz, the driver could go *much* faster but the motor couldn't!

Anyway, you can check out all the details here (http://www.fromorbit.com/projects/picstep/index.php) .

I'm thinking of getting some boards professionally made via CustomPCB, so if anyone wants some please let me know and I'll place an order. Depending on the demand I'll see what that costs will be. Shouldn't be more than $15-20 a board I reckon, but we'll see. Big order lower costs!

Cheers,
Alan.

A great job Alan.

Yep, it's fine to inline the site.

I've also added some photos and a little WMV of a motor spinning up and down etc etc. I'm going to put some finishing touches on the firmware, and then it's as good as done.

If anyone wants a professional board version of this controller, please let me know as I'm trying to guage demand before I commit to a quantity with the PCB manufacturer.

You can contact me via my email link on my website.

Thanks,
Alan.
