Shutter motor stalls and halts

Whether I use the motor switch or send a command to open, the motor stalls.

It won’t drive upward until I hit the switch or command it, three to four times. As well; when I send a command to close the shutter, it stops about half way down. Send another command and it stops again until sending another closing command.

Im not certain if I did something wrong, I’ve a defective shutter motor or the single track design; being one sided, loads up the motor.

I’m using strictly ASCOM to control everything per the instructions; e.g., setup and test phases.

Any help?

Thanks,

Dan
