Hey @jonweisw
Could you please take a look at this thread -> X2 is doing nothing (connected to E0 on RAMPS)
Right there someone described the same symptoms of his motors and provided a short video. If your X2 motor acts similar, you also should try to swap your X2 driver with for example the X-axis driver. If this issue appears at the motor of the Y-axis your driver might be broken.
If you are not sure how the electronic board is built up, you can see on this site under step 4 where which motor is connected -> https://genesis.farmbot.io/docs/plug-everything-in
If you still have questions or don’t know exactly what you need to do, we can give you more detailed instructions any time
