NOISY Core One

Hello, anyone know why this core one is being so noisy? I've wiped the linear rail and re lubricated with prusa linear rail lube and i used the new belt tensioning feature to tighten my belts good but it is very loud?

RE: NOISY Core One

This doesn't sound wrong to me - it once did but you get used to it...

For an experiment, try adjusting the speed from the front panel. It may shift the "noisy" features slightly in frequency. But for a more systematic way to quiet it down, check "stealth mode". 

Input shaper calibration with accelerometer may help (the input shaper finds resonant frequencies and suppresses them in the stepper input). And maybe this particular noise even improves with time (the rattling, not the high-pitched whine). At least I got that impression on my core one.

RE: NOISY Core One

redo the calibrations in the menus, it helps a bit.

See my GitHub and printables.com for some 3d stuff that you may like.
