Yea, I do prefer timing belts and used that on my plasma that goes up to 600 IPM on Nema 23 steppers. I did under size them at first for the X axis. Good thing precision is not an issue so I don't have to use the round tooth (expensive) belts the square tooth belts are good enough for this application.
