Need a little clarification.
April 21, 2014 06:34PM
Just got my RAMPS board for my first build. I checked out [] for the instructions but I am a little unclear on the orientation of the stepper drivers. Is there a pin one and what direction should it be oriented with the power connections pointing to the left as a reference. Also there were jumpers include in the kit but again I am unclear as to where to connect them. Any help or a point to the correct place on the wiki would be most welcome. Thanks!

Depends on your stepper drivers..

Jumpers go under the stepper drivers, normally you have all 3 on for 1/16 micro stepping when using a pololu or a clone.
all 3 its 1/32 micro stepping is using a drv8825

Same with orientation, they are all pin compatible with
(this is from the underside)

I tent to try and identify the thick tracks going to the steppers. And they go same side as the stepper pins.

The end of the driver that has the pot (silver circular component that has slots for a small philips screwdriver) faces away from the power connector end of the board.

This image illustrates it: []

position of the pot is not relaiable as there is at least one driver board with it at the other end.. (just to complicate things)

Thanks! I used a magnifying glass to look at the pin labels and pointed the A1, A2, B1, B2 pins towards the stepper motor header pins.
