I’ve had a similar problem with my left motor. I’ve used it for approximately 100 hours before left motor could only turn one side. Do we have any news from the manufacturer? I’ve already ordered 2 other motor from the maslow website.
I see you @Johnny5 have bought a another set of gear where did you find those?
Is the behaviour of your motor similar to mine (working only in one way and not well) or is it a complete motor failure in both ways?
