              Thank you Jonathan.

              Yes, the 2 reel motors are separated from the main machine. They are housed in a sub chassis that I designed.

              Wow. I'm knocked out. And you did that to isolate the transport from the electronics?

              Just to isolate the 2 reel motors to eliminate the vibration of the reel motors and spinning reels from the main machine.
              The side benefits are eliminating the magnetic field and heat of the reel motors from the main machine.
              I do not use the fan.
