Does anyone else's aux feeder sound like crap?

What are the default settings for velocity, accel & push_length in your buffer_stepper.cfg file?

Just found the post which mentions the settings I used.

Filament feeder

Velocity seems to be the setting which can quieten the buffer without affecting its ability to feed fresh filament. I put accel back to its default setting of 5000, & the filament fed fine from that point on. I now have velocity set to 30, rather than its default of 150. Doesn’t seem to have any adverse effect with regard to buffering/feeding, but it does make a notable difference to the noise level.
