I pulled parts from both printers to assemble a giant wilson II prusa variant.   I  will build a smaller core xy but It seems like I always have the same issues with the core xy motion. I will post a video as soon as I get it reassembled. I know it's something simple I'm overlooking.

Are you using the online firmware config tool for Repetier?

I believe wardjr is right in that you have one of your motors running backwards. Basically you need to flip the motor connectors, trail and error, until you can get the movement right first. Sorry I can't provide more specific help, but that's what I did until I found the right combination. Google Corexy XY movement for more specifics.

I redid the tension to make sure both rails were perpendicular as well. I have both x and y steps at 80. I'm running the most recent version of marlin I believe. I have run out of stuff to try.

When I move either axis the other axis moves as well. I figured both x and y should have same steps per mm.

Finally figured out the homing and end stop configuration, but the problem I'm having now is when when x or y moves the other axis moves with it. Is this the way core xy works or is it something with the way the belt is tensioned? One is with fishing line the other gt2 but both are pretty tight. Any help would be greatly appreciated.
