Check the operation of the visor limit switches - the machine is trying to see what the visor position is. Run a switch test to verify they are being operated.

I'm not sure why it takes so long for the eject hole in the upper left takes so long to register. Someone else may have other ideas.

I had an intermittent issue on my machine - the problem was a wire in the daisy chain for a column in the switch matrix. It took lots of hand over fist following of the wire to find the problem - a poorly connected wire at a solder joint - only two or three strands of wire were connected. Resoldered, and that issue disappeared.

FYI the switch test procedures (from @billc479) are at page 28+ of the manual; you can trigger each limit switch by hand and verify that their closures are seen by the MPU. And you can also run the motor via solenoid test #13 (at page 27) and visually inspect the limit switch closure action. Adjust switches (bend the actuators) as needed. Test the faulty saucer's switch as well (using a ball is more realistic than using your finger here).

Switch problems are very common, the diagnostic tests are your friend here.

Here is the pinbot manual:

You've got a switch problem. Look at the green/blue wire, everything that connects to it according to the switch matrix table (page 33 in the pdf). TUG on each of the green/blue wires to make sure that they are firmly connected to each switch, not just the Visor/Up or Visor/Down switch, because the break in the wire could be earlier in the chain.

Similarly, the White/Blue or White/Violet wires, tug on every connection to every switch, see if you can find the 'almost not making connecton' or 'not making connection' problem.

Similarly, the Eject Hole (left and right) switch wires, trace them down, tug on all the connections to make sure nothing is barely connected or occasionally connected.

Of course, you could just have a flakey or bad switch, which is a lot easier than tracing the wires!
