Introduction: "Deux" K'nex Ball Machine

Currently, this is the first ball machine on this site. Anyways, this a relatively small and simple ball machine with two paths and a motor driven chain.

I think this Is a bit Self explanatory, but I will tell you anyway.

Congratulations, You have Finished Project DEUX!!!

Step 20: Troubleshooting

The DEUX is an advanced piece of K'nex machinery, but it does have its flaws. Here are some Common Problems.

P: My motor is not Running.
A: Either the batteries are dead or the motor is broken

P: The Ball Gets Stuck On the three Identical Paths.
A: Push the edges apart or remove the grey connectors on the paths.

P: The ball Does Not Make It over The loop
A: Check If the Tubing Is on correctly

P: The Ball Grabbers Always Snap off!
A: Try removing the central Grey Connector From the path in the base.

If you have any other Questions, PM me and I will post the Solution
