My name is Silvio and I am from Brasil (www.feitoalaser.com.br)
I would like to know if anyone knows how to tighten a X-axis belt on a Gcc Mercury II?
Many Thanks

I don't know the Mercury II specifically, but if the belt system is the same
as the Mercury, then there are small black plastic plates where the belts
attach. They are held with two allen head screws. Those plates have grooves
cut into them to match up with the teeth on the belt, so that they have traction.
If you loosen the two screws on one side, you can pull the belt in another notch
or two to tighten it.

The plates are about 1" x 1/2" black plastic and have grooves on both sides.
This locks the plate to the belt when the screws are tightened.
I always get the X and Y rails mixed.. this is the one that controls Y movement.
the other ones are on either side of the flying head. But follow the belt.. it will
always lead to these.
