I agree with you. The Prusa calculators helped me to visualise the real difference between 2 and 3mm pitch. It is near nothing in term of accuracy for a tool which extrudes melted plastic.Quote

I don't think 2 or 3 mm pitch makes any difference, especially if it is GT profile
I don't think so : one full turn of a 3mm pitch driving pulley is the same full turn than a 2mm pitch driving pulley of the same diameter: it remains a full turn, and the length of ''moved belt'', is the same. So there is no gain, or loss for speed.Quote

I suppose you get faster with the larger pitch, and a new controller to divide the steps more.
I would be glad if you can point me to a source of Genuine GT2, 2mm pitch, 15mm wide GATES belts.Quote

(and GT2 2mm can be sourced in 15mm wide as well
Yes you are probably right. But...everything is in the word: ''probably''.Quote
gmedlicott
as the digital dentist mentioned, it probably doesn't have much effect in practice, as there are other larger contributing factors to accuracy

in the same way a 5mm lead on a screw would be faster than a 2mm lead

Misumi USA has everything to answer this question hereQuote
MechaBits
but I wouldnt know the diam of a 20t gt3
an interesting point: I must to think of it twice, before making the choice of belt widthQuote
leadinglights
Wide belts lever on the shaft more than narrow belts as narrow belts can be set closer to the flange.
