Mike-

Thanks for pointing to a key GDC decision and associated rule- I found them quite helpful.

We are still investigating the idea of powering our EM with multiple voltages for different release forces which may become slightly cumbersome using Spikes. One team member suggested a servo mechanically turning a potentiometer.
That's why we decided to check with Luminary Micro to see if they would give the OK for our specific application.
