The fan is loud, was wondering if anyone has tried running without it? Do the temps for the motor controllers get too high?

What does the correctPos ("CP" serial command) do? It seems to only get called on a collision, but I don't understand why it recalculates / resets the position based on the encoder only upon collision.

I have the ds3225 servo that came with the gripper kit, and my gripper seems to not put constant pressure when holding an item. The gripper/servo bounces and tries to grip again. The guide suggests that the servo should be trying to put max force and will heat up, etc, but that doesn't seem to be happening. How can I fix this?

J4 motor did a full 360 when using the Ry/Rx and Try/Trx buttons in the software. Now my wires are wrapped around the housing and I can't get the J4 motor to go back to where it was. I need it to move 360 clockwise, how can I do that?

Both linear rods in the J5 assembly are sliding out and in when the J5 motor is activated. I have used the set screws and loctite, but the motor seems like its too powerful and breaks the bond. Has anyone had this problem or a solution to it?

I see that in some posts, this is machined aluminum, but in the guide it says to print it. Is the AR4 kit supposed to come with it or should it be printed?

Has anyone made a leader arm for the AR4? Are there cheaper motors we could use that are drop in replacements?
