[Dsg-rich] [EXTERNAL] Re: d0 test station CCD stand stepper motor controller?

[Tyler Lemon]

Hi Marco,

The stepper motors are still at JLab.

I'll double check to make sure I didn't overlook the controller.

Hi Tyler,
actually, I don't remember if we brought the controller back in Italy.
Are the step motors still there? It would be strange that we took the
controller but not the motors.
