xl vs. HTD (again ) was Re: run two geckos from same pins

Hello,

"Regular" readers can skip this as you've seen it before :-)

The xl 1/5" type timing belts have a tendency to slip, and this will
be made even more likely as the belt "stretch" that 118" centers will
allow is entered into the equation.

Use of the HTD metric style belt will help considerably, as
its "parabolic" tooth form is just plain better technology. It also
will work reliably at lower belt tensions than the xl type.

Hope this helps.
