Re: Toshiba TB6600
A certain amount of noise is expected when using a chopper driver, but the 6600 is especially loud as far as I can tell... the TB6064AH is much quieter. The Linistepper is very quiet if that is a hard requirement for you. Some research places use it to position sensitive sensor probes, because if they use choppers, the EMF and vibration from the motors swamps the signal they are trying to pick up.
