Connect the -ve of the battery to the -ve signal input on the amp and also one side of the pot, run the +ve to the other end of the pot and take the wiper of the pot to the +ve signal of the amp, that should work :)

Just a wee warning, you will likely get creep even with the pot set to min as there will still be mV getting through so dont leave the drive enabled and wander away if the motor is still hooked to the machine.

none of the motors are connected to the ball screws but I will keep that in mind. So should I have purchased 2 9V batteries and connectors and hook one up the correct way and one up backwards?

No one is fine, you can if you wish just reverse the signal connections to test the amp the opposite way. If you were going to be making up a battery box that would be used many times over the coming years for testing amps then it would be an advantage to make up a -9 to +9v box like I did but for one off testing I wouldnt bother.

So I did what you said on the X axis. It worked like you explained there was some creep. It was almost stopped minor creep then medium pace and full on rapid. Now what? Should I test the rest of them in both directions?
