I just replaced the power cables, not the encoder cables, and I didn't use shielded cable, I used the same stuff that is pictured. I used 12/4 AWG.

I will replace cables. You changed the power and encoder? Given the color and the type of cable, I do not think this is the original cable. For power, did you use shielded cable?
