Re: Afraid to use my "Z"...not sure if stepper or driver is acting up...

I thought I should have mentioned the heat...it was a good 80° or so
in my shop...I have the 3 Geckos mounted on an alum. plate that is
~18"x8"x.625" and it was pretty warm to the touch as was the Geckos.

Thanks, I'll try the fan and keep an eye on things.
