In general about the BIX
The DC controller has very good rotational stability but doesn't use feedback as this can lock speed but trash the sound as it hunts for the optimum speed. There are good feedback controllers but come at a high cost.
Any of the following issues can affect stability:
oil or soil on belt, pulley or rim. Also improper belt tension.
Scored or lack of oil in the bearing.

We received some parts back and the user had taken apart the bearing and caused damage. this is very easy to do as the tolerance is very tight and the spindle steel is very hard. It is very easy to score the walls of the bearing housing putting it together.

Also some sent back the pcb controller with burned out resistor due to not following the start up instructions in the manual.


If any have a problem they are welcome to return the bearing and the pcb controller and we will test it. Aside from the external problems mentioned, these 2 parts would be the main concern.

regards
Brian
