Thanks for the graph. To balance the scope would you use heavier weights closer to the RA axis to minimise moment of inertia or lighter weights further from the RA axis to reduce overall weight on the

Hi Bryn, So when the cable in the DEC socket on Gemini was connected to the RA motor, the RA motor ran uncontrollably? That does sound like a problem with the Gemini unit itself. Could be something

Thanks Brendan and Paul, So I swapped the dec cable to the RA motor and the fault transferred, so immediately thought that the cable was at fault. However, during various other tests, the fault stayed

Paul is spot on swap Ra motor to DEC and visa versa. Keep track of which part started from. You can remove the motors and run them on a bench to test. They don’t need yo be fitted yo test. if the

Hi Bryn, Continuous uncontrollable slew indicates that Gemini isn’t reading the encoder from the DEC axis servo motor. Things to try: - make sure the motor cables are not broken by swapping them. If
