First layer defect and strange noise

Hello everyone, for some time I have had defects on the first layers of my Hueforges prints. Each time the print deteriorates, I hear a dull friction noise and obviously this noise comes from the plate because when I put my hand on it, I feel a slight tremor.

I have 2 x1cs so I tried moving the ams and file to my other printer and everything works, so it’s not a G-CODE or filament issue.

The machine only has 250 hours of printing, it is up to date and I have already carried out 3 complete maintenances, each time followed by a complete calibration. I do not know what to do.

The machine as it stands is unusable. The photo I put is a hueforge on the 4th printing layer, see the condition yourself…

I remind you that the settings under bambu studio are the same as those I have on another printer which does not encounter any problems so I think we must turn to the printer itself but what to do? I have already done all the maintenance recommended by the manufacturer.

If some of you can direct me to know where to look, I would be very grateful, thank you all and happy printing!

Welcome to the forum.

I don’t think you can draw such a conclusion just yet.

Have you tried a simple first-layer test? By that I mean take a cube primitive of 240x240x0.20mm and see if the printer reproduces the problem. I’ll wager it won’t. What makes me say that? Whenever I’ve tried to print a geometrically intricate model with a large Gcode file, I have exactly the symptoms you described. I learned that’s because of all the micromovements of the nozzle that involved. What you’re hearing is all the changes in course the random Gcode is asking of the servo motors. Now if the sound goes away using a first layer test, that more or less proves that you’re printer is fine.

My first discovery of this phenomena was trying to print out this beast at 0.08 layer height

I had the printer less than two weeks and the terrible grinding noise made me think the printer had just destroyed itself. I didn’t dare attempt it again for another month once I was more confident in how the machine was supposed to operate.

Thank you very much for your answer. Indeed, I only have the problem on this type of printing however as I specified in my first comment, I have 2 x1c and the other does not have this problem at all and the layers are magnificent using the same filament and the same G-CODE, that’s what it tells me that the printer has a problem that I would like to identify. It is true that I will only have one printer, I would not have asked myself the question. But as you see my photo, I can’t let the printer print like this, I hope to find the solution or a direction to follow here.

Thank you very much for your intervention! :slight_smile:

Any update on this ,as I have similar on my 0.08 layers on hueforge prints .
All BL pla and 0.4 nozzle .
I have my textured plate on and will try a smooth one later but until then any update on what grinding noise (maybe as above said servomotorer) or is it tensions in belts ?

Well I have my X1 carbon with the newer ams . If that helps and everything is maintained and checked .
10% on my hygro in the ams .
I put some pics in here and it’s the first time I try that here so bare with me :wink:




Did the first layer or two go down well in that example? What does the other side look like? I speculate that a grease spot caused lack of adhesion there, it’s the only way I could see that mess happening.
