RE: DRV8825: Large audio noise with 3 drivers enabled`

Hi Rick,

Sorry my mistake. Should have set the motors to a hold position. New vid - goo.gl/.../mtEkepMRubK2pMqi8

Again, when there is only 1 or 2 motors the noise is very much reduced. Is there a reason that multiple drivers on the same board would directly effect each other? We have a large 4700uf capacitor in place to reduce any voltage spikes.

I saw from the related post you mentioned that the sense resistors require a good path to ground. I've tried to implament this with wiring on the board but it made no difference. Also reducing the current only has a marginal effect to the noise.

I will attempt to try with the motors in a fast decay setting.

Any other advice would be greatly appreciated,

Jack
