Sorry if this is a double post.
Later that night...
- So I took my box apart and surprisingly none of the gears were broken/bent in any way.
- I re-shimmed and as I was turning my gears and aligning them with the piston, I found that my piston teeth were damaged!
- on the third/fourth tooth it looks like the gear had crushed the plastic and won't fit in between the teeth anymore
- So essentially it got stuck!
What could have caused this? A bad AoE?
Would filing the spaces in between the teeth solve this issue? Or do I need a new piston altogether? How can I avoid this from happening again?
Any help would be greatly appreciated.
