Parameters and Current Consumption
One possible issue is the current consumption.
The specification sheet also warns of high temperatures, but the controller takes care of them. So selecting the right parameters is key. I selected iRun = iMac = 3 or 100 mA. |

I've measured the total consumption of the model with 2 steppers:
So a standard 9V fischertechnik battery supplies the whole model easily. The model includes the Arduino mini, a Bluetooth module for debugging, the 2 stepper controllers and the 2 stepper motors. |
