I actually solved the problem with mine. It was the cog belt had to much tension on it and was rubbing tightly against the metal pulleys. I went to AutoZone auto supply store and purchased some v-belt dressing, sprayed it on q-tip cotton swabs and wiped it on the edges of all the cog belts and the machine is a quite as it was when I first pulled it out of the box. You need to verify how tight the belts are and adjust them with the four hex screws holding the servo. The holes are slotted and allow minor tension adjustment. They need to be taught, but not so tight they act like a spring when you squeeze them together.

My machine has started making a funny "clicking' noise in the y-axis movement. I have cleaned and lubricated everything just short of disassembly. The problem is that I cannot determine where the noise is coming from as it is coming from everything I put my ear or sound "probe" too. Any suggestions?
