I am designing a new belt driven x-axis for my laser. I would like to know how Epilog, LaserPro and other quailty laser cutters drive there x-axis (The axis that rasters/engraves)

I think they will all be belt driven, but are they direct drive with a pulley on the motor shaft or do they have a reduction gearbox?

If somebody with a nice machine could post a pic of the drive setup that would help me out.

Cheers
