**Question for the group…** or specifically those folks with _ **1f 1gen machines running their blackbox** _ (clone buildbotics) controllers…  
And more specifically.. those still suffering with the “spindle drop issue” where the weight of the spindle “drops” with e-stop or power loss.

I’ve recently come across an open-loop stepper with an electronic brake?

Recently acquired such a stepper and worked with Doug (over at BB) to power the brake-release during use… I have the technical details needed… but before I dig into this project I wanted to gauge interest.
