I'm having an issue with my topper and was wondering if anyone has any ideas. The martian is getting stuck so the it doesn't jump like it should. When I run the topper in test mode, if I lightly push up on the martian's arm it'll start jumping and run until I stop the test, and depending on where it stops in the cycle it'll start up again and work but then if it comes to rest at the bottom of the stroke (in the 6 o'clock position, where it most naturally rests) it gets hung up and will stop working. There were a few sticky spots on the gears for the motor so I rebuilt it and it spins great now, so I'm confident that isn't the issue. Has anyone else had this problem or maybe an idea about how to proceed? Obviously it's not that important of a detail, it's just annoying.
