Indeed! Poly-Vee belts are acceptably quiet but of course then you need
to rig an encoder.
Probably a decent trade off. Available, not too expensive, transfer
power well and seem to last.
Years ago I made both of my pulleys.

You need t take several steps
1) verify the belt and pulleys have the same tooth profile. They need to
match exactly.
2) if the profile is "square teeth" then yes, these are noisy. Decide if
you want to spend the $$ to change the profile because no amount of
adjustment will make a square tooth
Regarding belt tension. Goal is to get engagement with the minimum amount
of tension. This ensures the bearings on motor and driven pulley shafts
are not overloaded.
I work with very large bearing and or bushed machines. (Crushing
equipment). Standard rule of thumb is 1/64” of deflection per

It could go at the bottom, nearer the drive motor.
The belt on my Holbrook is a rather wide poly-vee. Very quiet. I

If it quiets down with pressure applied to the back of the belt, something
like this might do the trick.

I have managed to get two AMC 30A20 servo amps on eBay, one
relatively cheap, the other somewhat expensive. Now, I need
a 3rd. These are 30A peak 15 A continuous, up to 180 V DC
input.
These match the current specs of the NC400's that came with
the machine. But, for the Z axis, maybe less

It doesn't add any backlash, but nor does it reduce it at all.

If you have a 3D printer, you could try making a floating tensioner:
