Quoted from Vespula:
Right spot finally needs repair.
The assembly bracket holding the bottom screw in the vertical servo broke. I think servos are fine.
Now I finally get to use the other half of my spotlight upgrade kit and install emax servos I've been saving for this day.
Lasted almost 1500 plays... that's pretty dern good I think.
That is a fantastic run. I'm at about 1700 plays and I've gone through several brackets for the same reason (the little eyelit breaks every time). JJP replaced mine under warranty each time, I'll say that for them, but it is annoying to have to keep repairing them.
Nonetheless, another point of failure I've found is that even if the servo doesn't die and bracket doesn't break, and the actuator doesn't break, I find the spot that the gear goes in the actuator gets rounded out, so the actuator arm just slips on the gear and moves erratically, or not at all.
The mezelmods spotlight parts have been out of stock for months. Maybe they are done making them forever? There designs on Thingiverse that are vastly more robust than the original, if you have access to a 3D Printer that can print in PETG or Nylon.
