Actually this is something I was also wondering about. I know that when I switched my reprap from T5 to GT2 belts there was a significant improvement in quality. That being said I'll probabley start off with the standard MXL belts just to get everything up and running and tinker later.

It does make me wonder however, if there was a specific design reason that Bart chose to go with MXL belts for usage with Makerslide..

Curious if anyone else has any input on this topic.

Curious about the same thing... see my post here regarding the torque rating on these mxl pulleys

Just to straighten this out: It was my choice to use MXL with project Shapeoko. For Bart's applications, MXL probably works fine as the original design was intended for his 2.x laser, where not much torque was required due to the nature of the machine where speed is valued over torque.

As far as why did I chose MXL? I looked around and found that MXL was a popular belt choise for other projects, and it fit my cost requirements. I bought a length of belting and a pulley, and tested them out. I never looked at the torque chart for the belting because they seemed to work fine (and still work fine) for me.

I have yet to try a different belting (like G2 or T5), but would be really interested in comparing the results.

Thanks for the explanation! "it worked" seems like a fine test :D

GT2 and PowerGrip technologies were difficult to get from our DIY world, with a simple shop and Paypal.
Was a lot of discussion in the Reprap world to enhance printing, but availability was the problem.

Now, not only the GT2/PowerGrip has a superb argumentation to compare with vanilla timing belting, but buying them is easier.

The "next step upgrade" is V-wheel type: Delrin/Makerslide seems suited for 3D printing and light CNC, but what GT2 can offer to CNC (increased force) means that metal V-wheel are needed, not supported on Makerslide, I would dare to say.

But GT2/Delrin brings precision gain and Shapeoko can surely take an advantage by upgrading.
Why not considering a group discussion to agree on:
- Belt type (pitch & width)
- Pulley (nb of grooves, other)
- Idler (standard or custom)
... and submit a "GT2 upgrade pack" to Eedward? (As he did for new plates) ! :D
