Re: Extruder stepper missing steps..

So,

I have replaced the polulu, no refief
Now I have replaced the nema17, same problem persists.

I notice there is a small wobble in the gears with a moment of slightly more friction. However, No real problem with moving by hand.

Is it possible to increase power to the motor to overcome the friction ?
Is power adjustable ? In the polulu or in the firmware ?
