Servo stops working unexpectedly
I recently finished building the sphere bot. I have been able to print some eggs but it has been a struggle. When printing the servo will just lock up. It makes a buzzing noise until I pull the plug. I have to leave it unplugged for a couple minutes before it stops doing that. My values right now are at 40,50 and the servo is in the right port. I did try some other values too but I get the same issue. Please help.
Try adjusting the UP and DOWN position of the servo in the eggbot plugin MENU. An UP value too high will lock the arm up and the gravity will not be enough to take it back. Additionally, check there is no friction on the pen arm.
