Quoted from zaphX:
Well, I spoke too soon about it working itself out. I am getting regular failures now. Frequent but not 100%.
- Chest opens only a sliver of what it should.
- When the chest closes, it rises to its full height, then closes.
- Sometimes on boot when it does the open-close thing, it doesn’t open all the way there either, making a whirring noise when it stalls.
I don’t think the linkage is binding, but I’ll check it again.
I’m assuming the bootup sequence doesn’t care about the state of the microswitch, so the control arm for that is unlikely to be the culprit. I am guessing this is a power issue and it doesn’t have enough power to pull it down.
Open/close sequence on boot sets the servo to zero, opens and closes and then sets itself to match the position of the switch. So you could just see an open/close or an open/close/open. The first movements not being related to the switch at all.
If your switch is being fully contacted by the bushings and giving a clear clicking sound, then it is unlikely that. Since the chest triggers (it sounds like) but the movement is lacking, I would suspect the switch is fine. You could test it by just moving the forks out of the way and manually triggering the switch. Does it function properly then?
But more likely it is binding up. It doesn't give a full test doing this with the playfield up since gravity doesn't come in to play like it should, but in testing does the thing move fluidly?
I am going to make a video right now about my thoughts on the rod adjustment. That seems to be one of the biggest questions or hangups.
Maybe with this new flexible rod all the issues will be solved.
