Re: MAGIC SMOKE Xylotex drives

Hi Bill,

You keep saying "blowing", as if they're resetting themselves.

I (somehow) did blow one driver on a 3 axis Xyltex board, and when I took a
meter to the outputs (power removed of course) of that driver - dead short.

The Xylotex board has a surface mount LED, it will come on for a moment, then
shut off upon power up when one of more drivers are blown/shorted.

Are you seeing any of these symptoms?

Have you contact Jeff of Xylotex? He's really helpful in these situations.

Jim...
