10mm belt nema23

[Robin Hewitt]

From the HPC gears website...

Approx. belt flank play backlash are as follows:
T5 - 0.6mm
T10 - 1.1mm
AT5 - 0.2mm
AT10 - 0.4mm
AT20 - 0.8mm

Wonder if I could turn a 5.08mm pitch pulley down a tadge. The 5mm tooth seems a pretty good fit in that.
24t * .08mm / Pi = 0.61mm off the diameter. Might work. Or am I completely getting the sum wrong?

It is not that simple to get the pulley tooth size. You have the pitch line, which corresponds to the belt insertion, where the belt bends. From there you calculate the gap between the teeth to correspond to the belt teeth dimension. The teeth on a smaller diameter pulley are narrower than those on a bigger diameter...

If you tension enough the belt you'll have no backlash even with a smooth belt. The teeth are there for timing ... at times

But it looks like it might go, a small change in radius gives you 6 times as much off the circumference...

got my belt and pulley from cnc4you they match perfect, kev

Momentary hope, but they have nothing to fit my 15mm wide belt.

I think I might try 3D printing a pulley. Well, why not?

Is there a reason you bought pulleys and belts from different suppliers?

I don't think it matters where you buy them, the spec for the T5 pulley has 0.6mm of slop. I presume there is a good reason for this and it was not done simply to piss me off

They do 16mm wide belt and pulley, so these pulley suite your needs,
