[Solved] Sanity check on Prusa Mini noises while printing.

Just received my Mini the other day and got everything assembled. I would kindly request a sanity check on the sound my Mini is making please!

The noise is apparent during faster movements and during the straight perimeter movements as well. It has a grindy sound that I want to verify if it's fine, or if the bearings need lubrication.

While not printing, I notice that the bed generally requires a moderate amount of force to move by hand, and sounds somewhat rough as well.

I used PrusaSlicer's Mini profile at 0.2mm quality at 15% infill for this print, and am printing CHEP's calibration cube.

My Mini arrived with 4.0.2 installed, but I've upgraded to 4.0.3.

Well noted! I downgraded back to 4.0.2 and the movements are much quieter! It's definitely not as grindy as it was when I was on 4.0.3. I reprinted my CHEP calibration cube and it doesn't "grind" during the perimeters anymore.

Thanks for the tip!

4.04 is out now - it would be interesting to see if that version shows the issue or not.

Hello together,

yesterday I received my mini and I have exact the same noise but the installed FW is already version 4.0.5

In fact it is so loud that my girlfriend already complained about it while she is sitting in the room next to me. Ender 3 with silent motherboard is way more quite.  what can I do? is this normal? could someone post a video how loud it should be ? I was printing with the default profile in 0.2 mm QUALITY.

Thanks for the help.

Hello again,

I made a video where I move the bed by hand to hear the sound.
I printed a cylinder and the surface finish is not what I expected, at least not from a prusa printer and all the videos that I have seen.
The surface is not smooth, it has many small wrinkels and  artefacts. 

Best, 

Tommy

I’ve had my mini for 4 days now and have the same issue. The y-axis makes a loud noise as it travels. It can be heard throughout the house.
