I have my arm built and electronics installed.
I have gotten all of the steppers to work on the arm via the controller.
I do have an issue with the base rotation motor (1) It seems to be stuck in permanent motion in one direction.
I can stop it by moving the appropriate stick on the control just enough in the right direction.... a little more and it goes the other way. I release the stick and off the motor goes again.
Could this be that the control was not in its neutral position when the software was installed? or a dodgy control possibly?
Only one other thing.... the gripper seems to move on startup but not via the controller.
Is this indicative of any particular obvious cause I am not seeing?
