I am getting ready to start my "first print" just to find that my DSH is not fully switching anymore. As it turns out, the black servo arm (or servo horn) is stripped out where the arm connects to the servo (there seems to be some oil leaking from the servo). I can't just buy this black plastic arm; I have to buy a whole servo to replace it... Which isn't a huge deal, as they are cheap enough. But I have no confidence the replacement won't end the same way! I've emailed Makertech and am waiting on an answer. In the mean time, I have counted the splines on the servo, to 21T, and I am hoping to get a 21T aluminum servo horn to fit inside the red ABS cover (not really sure if I can get one that will mount to the MG90S, as this is such a small servo, it doesn't seem to warrant aluminum attachments...) Does anybody else have experience or suggestions on this problem? Servo replacement suggestions? Servo horn suggestions? I feel like this servo is a problem, and I'm not the best way to remedy it at the moment.
