Last Minute Problem Encountered with Turntable

I have encountered a last minute problem with the turntable. I have been running the turntable it has been working fine and responding to the instructions given. However, there is a slight jittering problem where the turntable would get stuck in its place and jitter from side to side but in the same spot.

After running this a few times, I started to notice a pattern in the jittering. At first, I tested the turntable with no weight on it, and it runs smoothly. Following instructions without any problem or jittering.

Here is a video footage of the above statement:

Here is a video footage of the turntable jittering, then working smoothly and then ending with jittering:

I have managed to track down the cause of the jittering. The problem is in one of the relays that are on my stripboard. The jittering is due to the magnetic switching of the relays.

I am now planning to use an IC which is a Stepping Motor Controller Driver to compensate this problem. The IC has no magnetic components therefore this problem will not occur again.

I have purchased the IC from eBay today and will have this problem solved by end of this week.
