Is there a schematic showing the layout of the board and what the jumper settings are?

I'm using 200 steps/revolution motors. Dual Y setup.

The board layout is walked through in the video instructions found at http://j.mp/Lal92X
It's a pretty straight forward build, with things marked on the surface of the board itself.

As for the jumper settings, I've reworked the truth table from the A4988's data sheet.

I've also added the table to the instructions page at http://www.bit.ly/getstepping

Can you give the pin settings for dual Y also. Thanks.

Sure thing. To reverse the direction of a single motor, you want to swap *one* pair of leads.
For example, in the directions at reativesubstance.com, the builder is directed to install the leads in order from left to right as green, black, red then blue.

Green and black represent one winding, the 'A' winding, in the motor. Red and blue represent the 'B' winding. Reversing either green and black, or the red and blue lead will result in the motor direction reversing.

I'll clarify this in the directions, too.

Dual Y Setup

Ok. Thanks I probably needed to know that to. But that isn't exactly what I was asking. Is this setup correct? http://www.shapeoko.com/wiki/index.php/Dual_Motor

Or does the (A)axis need 2 jumpers like the (Y)axis?
And on the 6 pin connector the 2 jumpers go on the (A and D) pins?

The video's I watched will putting it together but I had the volume muted to keep my girlfriend from getting mad will CSI was on. So I will listen to them later.

Hey Guys
where did you get them cool little 'smoke stacks'?
oh ah ,I mean heat sinks for the driver chip.

@chip: look for a "MOSFET heatsink".

I'm still not totally sure what you are after: so I'll cover multiple bases.

If you plan on using the fourth space as an A-axis, then you put two jumpers across oriented above the "DY" on the board.
If you plan on using the fourth space as an second Y-axis, then you put two jumpers across oriented above the "A" on the board.
This is a result of an error in the silk screen.

The link in your post, http://www.shapeoko.com/wiki/index.php/Dual_Motor , has a picture that shows the proper jumpers on the 6 pin header to run a DY motor setup.

As CV said, look for MOSFET coolers. We bundle sinks with the Pololu drivers in the online store.

ejs thank you. I think I have it figured out. Next weekend I will find out.

Hi EJS,

I was trying to order some of the bare PCBs to New Zealand and noticed you were sold out. When will they next be available again?

Thanks,
Harrie
