我有位朋友也遇到相同的問題 https://youtube.com/shorts/0Fd5uubn5Rg Denis也是說正常 that is a normal sound for a grinder. This is a mechanical device with a lot of moving parts. It will produce different sounds that come and go. There is nothing wrong with it. Use it
我當時是把影片直接以附件放在email裡的 這個回覆,我懷疑Denis沒有看影片 moving parts如果是指馬達,減速機那些,他應該就會直接說了 於是我再要求他看影片,磨豆機的刀盤都拆掉了,異音應該來自培林底下 然後他回 I am sorry but it is normal. Likely the noise is from the drive key which is loose.
Daniel, the noises are normal, its a grinder that crushes coffee with large burrs, it will generate all kinds of noises that change and come and go. Noise from your video sounds like vibration. Something is vibrating. When you hear it place your hand on different parts of the grinder to find out what it is. Safety cap on top, portafilter are the first things to try.
