My application is relatively low speed with small (NEMA 17) motors, and I have
not had noise problems but am running a very short distance.
There are also other drives that use the Allegro 3977, but I do not remember
them off hand. A simple internet search search will probably find them-one
even sells kits and bare boards for those who don't mind assembling surface
mount by hand.
For low speed low power price sensitive applications the Xylotex or other drive
based on the 3977 is probably fine, but you are right that for faster, smoother
motion you need a drive that can deliver more power, such as the ones made by
Gecko.

Subject: Re: [Emc-users] Xylotex Drives
Xylotex drives are not optoisolated, which may cause noise problems, which I
experienced.
Also speed is limited due to a voltage limitation of 24 V.
I use Geckos 201 now and happy - speed is high and no noise. Motion is
extremely smooth.
They cost more, though.

from BDI v2.05 (.06? something like that).
