Pitch of t2 timing belt (2 replies)

I ordered a t2 timing belt with pulleys, and installed it on my printer.
I now have all my electronics wired, I have noticed that the printer is not traveling the right distance when I tell it.
I got suspicious of the belt, and whipped out my calipers and measured it. The pitch on it turns out to be about 1.75mm.
The printer only travelels the right distance however, when the pitch is set to 2.5mm
I thought that t2 timing belts by definition had a 2mm pitch.

Please help, Max
