Hmmm… maybe more than one issue here.
First off: I’m sorry to hear about the damaged wire– do you think that the wire is possibly broken other than just the loose end being broken off? (If necessary, we can send you a new motor, but you’ll be up and running much sooner if the problem can get sorted out with the motor that you already have.)
In any case, it sounds like you’re still not getting a good connection on one or more of your motor wires. The two motors should give identical resistance when they’re hooked up correctly and energized. I’d suggest removing all four wires from the terminal block and inspecting the ends. Make sure that the metal are cleanly exposed on each, and inserted to such a degree that the terminal block will make a good connection. Once inserted, pull gently on each wire, to make sure that they’re held in place.
If you still can’t get a good connection, you might try (A) stripping that green wire a little further back and trying again and/or (B) swapping the wires between the two motors. If the problem moves with the motor, then that would confirm that it’s some sort of an issue with the wires (or less likely, the motor itself). If it does not move, then that would indicate that it’s actually a problem with the EBB.
Separately, I would have expected that if you were trying to print, you should still have one motor moving, even if the second were disconnected. So, there may still be something amiss. If Robopaint appears to be moving *very quickly,* it may be in “simulation mode,” which is what it does when it does not have a connection to the WaterColorBot. (When you launch RoboPaint, it will indicate very clearly if it cannot find the WaterColorBot– if you haven’t seen this, disconnect the WaterColorBot’s USB cable and restart RoboPaint, so you can see how it reacts to this situation.) You can also test this by asking it to lower and raise the brush. If it has a good connection and power, it will comply.
