Hi, yesterday i got my Eggbot board ( exactly this one : http://www.watterott.com/de/EiBotBoard
The firmware update etc worked fine but when i try to adjust the vref of the the stepper drivers I realised that in every position of the poti, vref stays at ~2V (measured on ground and the vref pad near to the poti). Driving the steppers with this config heatens the motors and the drivers too much
Is there a design error in the version of the board?!
My second problem is the servo which isn't working. Sending a command to move it lets the servo make noise but it doesnt move...
Can anyone help me please ?
Thx in advance
