Re: New Article Posted

Nice Article Phil! Thanks much for the information.

I also wanted to say good looking stepper drivers too at a good
price. Looks to me like this is a great resource for those that are
a bit afraid of the soldering gun while at the same time being a
great value!

I will be referring folks to you for their stepper driver needs. I
must admit though that I have the Hobby CNC driver on my router, and
my "own design" on the little machine I am making now. But, @
$29.95 each for your drivers, assembled, you are surly providing a
good value!
