solved the problem, but don't understand the cause.
I used digital pins for the autodrivers 5V and GND. Once I use the mega's 5V pin however, the autodriver works properly.
Even though the pins are pulled first thing in the software, followed by a 3 second delay.
Any idea why this happens?
I'm using a buzzer to indicate before and after the command. If I plug in the battery first and then the USB (before the command), the Arduino doesn't reboot, as the first buzz doesn't repeat. The motors then turn.
I've got a problem when using a 12V Lipo to power my Arduino Mega2560.
A move command gets executed, when the Arduino Mega is connected via USB and the Lipo is hooked up to the AutoDriver and Vin of the Arduino.
The move command doesn't get executed however, if I power up the project only via the Lipo (connected to Vin and the stepper Driver). When that is the case, the Arduino 5V reads 5V, also on the Stepper Driver.
And now the weird thing. When powering up while USB and Lipo connected, my example code waits 3 seconds for the stepper command. In that time I quickly unplug the USB and the move command works.
I am using a buzzer tone before and after the move command which means that the code doesn't get stuck anywhere I guess.

is there a chance for an stp or stl file of this board?
No public wish lists :(
