servos and heat
I have killed a handful of servos, both "low end" 9g servos and the better very precise metal geared ones I use for my R/C airplanes.
I think it may be due to heat, the servo being too close to the hotend. Servos are not made for this kind of extreme heat. (Its around 5-6 cm behind the hotend, and the hotend runs at 250+ degrees most of the time, sometimes more, and around the servo it has to be around 150 degrees, at least.
.
I am about to make an IR proximity sensor instead - but they have issues with lighting disturbing the IR sensor.
Has anyone else experienced this or am I imagining things - and if so, has anyone tried to insulate the servo to protect it from heat?
