smoking miniengine - 24images - 10-03-2015

I am using miniengine controler with a 4 meters track. So far a lot of nice results.
Positionning the track with an important slope for a nice "crane shot effect".
A the end the limit switch stopped the dolly, then, the dolly goes quickly down the slope, effect of its own weight.
The problem is that the stepper motor generated electricity and burned the easydriver shield.
I am now waiting for a new easydriver to fix my controler, but I'm not sure that I didn't burn the whole controler...

Is'nt ther a solution to keep the motor in a stopped but not "sleeping" mode when you reach the limit position either with limit switch or maximum steps limit ?

The miniEngine 1 has unfortunately no such feature. There is only a software solution for this on the newer miniEngine v2 (keep motors powered).

Do you think that some kind of electrical protection could be add to stop this "back current" from the motor as a diode ?

There is a simple software solution but the development for the miniEngine v1 is stopped due to the new v2 and the fact that the memory is full (no more space foe additional code and features).
Cheers.
