Two screws holding motor to central diff housing keep coming loose after a couple of minutes of running the car no matter how tight i do up the screws. I have tried stronger washers and re-printing a fresh central diff housing with fresh slots. Does anyone have any good suggestions for overcoming this problem as its driving me crazy!!!
Use blue thread locking fluid if screws are coming loose because of the vibration.
I think its more likely coming loose from the motor making the 3d Printed parts “soft”. The motor gets very hot and maybe transfers the heat to the area where the screws pass through the plastic housing so they come loose? Is this possible do you think? I will try threadlock and see what happens…
how hot does your motor get? more than 100°C ?!
no idea how hot but enough to soften the 3d prints…maybe i should make central diff housing in ABS not PLA?
maybe bit if it melts PLA it would probabl do the same to ABS
are you using this motor?
