Hi.
I could not find where this issue come from.
I have waves on the first layers.
It happens only when printing large surfaces. I tried other filaments without success.
Could it come from the heat bed ?

Have you already face such issue ?

Thanks for your help.

Most likely cause is the nozzle too close to the bed for the first layer. Make adjustments in small increments and see how it goes.

Also if this persists through several layers then it could be over extruding also.

Thank you Wirlybird, you are right. The nozzle was too close.
Thanks to Duet3D controller I was able to modify the Z offset during printing by +/- 0.05mm step
I have to add 0.15mm to solve the issue, that's huge

Thanks again.

Great to hear and good job making small changes and waiting for the result. That's exactly how to fix issues in printing!!

Almost perfect, isn't it ?

Yes! If you get a little bit of that wavy (baconing) pattern it is ok since it will probably get covered over by the next layer. If it does persist through more layers then it may indicate a little over extrusion.

Ok. I'll test deeper, and try to have perfect surface
