Problem on first layer with Alfawise U30

Filament 3D Printer Technical Help
1

Hello,
I am a beginner in 3d printing with an Alfawise U30.

The printer is assembled and seems to work.

I have installed Cura to have Gcode files from stl files with the Alfawise U30 profile.

I tried to print little objects but I have always the same problem : the first layer is bad, no details appeared.

So, to have a reference, I got 3dBenchy stl file and generated a Gcode file with Cura.

And like the other tests, the first layer is bad.

And then, I wondered if maybe the problem can come from the way the way Gcode is generated.

So, I made a test with the 3dBenchy Gcode file delivered with the Alfawise U30.

But I had again the same problem : the first layer is bad.

I don’t know where is the problem and I don’t have much experience, so I want to ask you if you can help me with this.

Thanks

Hello there,

For your first layer make sure that your z-offset is set correctly: https://all3dp.com/2/z-offset-3d-printing-how-to-adjust-it/

If you don’t have success after trying that just let me know and I we can see about something else.

Thanks,
