does anyone else’s aux feeder sound like crap? make a beeerrrrrrttt noise every time it feeds additional filament. I’ve taken it apart and everything looks fine. any help would be great!

I don’t have a Max so I can’t comment on how it sounds. The aux feeder uses a TMC2209 motor driver in UART mode. [buffer_stepper filament_buffer] step_pin: buffer_mcu: PA8 dir_pin: buffer_mcu: PA9 enable_pin: !buffer_mcu: PA11 microsteps: 16 rotati…

its sounds like a duck quacking every time it feeds . when there is no filament in it and you activate it its much less noisy but sounds like a duck quacking every 10 seconds

I’ve reduced velocity to 50, & accel to 1000 on mine. I’m currently testing it on those settings. It quietens it notably, & isn’t currently causing any issues feed wise. It’s worth experimenting with those two values.

I replaced mile with a Infinity flow s1, no more noise, filament runout no longer an issue.

The noise of this one is now down to around half, possibly slightly less, of what it was. Reducing those speeds helped. I’ve also removed the grease from the internal gears & lubricated those with wax, as I noted slight gear noise. That’s gone now. Finally, reduced the travel distance of the tube/sl…

Did you have any issues getting the S1 to fully push the filament into the printhead?

couple of years later now, I can confirm these numbers are very good.

I eventually found the best settings were to leave velocity at its default setting. accel: 5000 Velocity I adjusted to 30. velocity: 30 Setting accel too low can occasionally lead to the feeder not recognising when filament reaches the extruder. Velocity seems to be very forgiving of its setting…

Mine sounds terrible, too. It’s extremely loud.
