If you still have issues, you may need to do a firmware reset from the Machine Inspector.
Open up the Machine Inspector by going to Machine > General Settings> Machine Inspector.
In the Machine Inspector scroll down to the console and send this command:
$X
Press enter. This will unlock the machine. Then send this command:
$RST=*
Press enter.
You should receive an "OK" message that the reset was successful.
If you still have issues, it may be a mechanical or electronics issue and you'll need to reach out to your machine manufacturer for additional support.
