• Thanks for the direction. I tried the non-operating motors on the M1 terminal and they both ran fine, so the motors are good.

    I called Dimension Engineering and spoke to Charlotte. She came to the same conclusion as you that the controller is toast. She sent am RMA for me to send back the controller and they will diagnose the problem and either…[Read more]

  • I built an ATR kit with 42mm motors. All is wired as instructed and the robot will run properly but only until the ferrites get hot and then the 2×25 Sabertooth controller errors out. Can anyone tell me why the ferrites would be hot enough to blister your finger after only running for 30 seconds or so? I am suspecting the capacitors across the…[Read more]
