Strange Artifacts on First layer
Hi guys,
I have these strange artifacts during the First layer.
I clean the bed with isoprophilic alcool a lot and warm the bed at 65 degrees for 10-15 mins before launching the print.
These errors come random in my First layer,not at the same areas.
What can i do?
Best regards and thanks in advance

Nozzle likely just slightly too close to the bed.. it pulls up the neighbouring lines when too close and causes these waves
So the mesh doesnt work i think

Mesh has nothing to do with z-offset
The Z offset is good, some areas are flat,some areas are to squishy
So It s the mesh

Too much squish causes pressure in the hotend to vary and will cause varying extrusion widths. That’s likely what you’re seeing.
Do you see minute areas of the bed mesh that vary in these areas only? Your OP says they appear in random areas.
"Do you see minute areas of the bed mesh that vary in these areas only?"
Yes, after a lot of print i can see an Area that is more squishy then others, in the left corner

I meant on the visualized bed mesh, in Klipper, not on the physical bed.
yes also in the bed mesh in klipper
but is like "reverse"

Check https://discord.com/channels/582187371529764864/1123972418428489749, I have the same when it seems mesh ignored
Ah, you already there, sorry
try to find a solution
I have SuperPinda Probe and i would ask if the default settings in RatOs are OK.
Also the X and Y offset. I have the default probe mount printed and installed.
I have enabled "Invert Z Control" into Mainsail. In this case "making the bed move down when you click the down arrow"
I have checked my bed plate and i think is not twisted or similar issue.
I will post an image.
I have a Z-Offset like 2.000
i followed the ratrig procedure to install and set the correct Probe distance from the bed and the nozzle:
STEP 38
https://ratrig.dozuki.com/Guide/09.+EVA+3.0+Assembly/142?lang=en#s1051
"Adjust the probe up to down as necessary to position the tip 1mm higher than the hot end nozzle"
Last action will be delete and reinstall RatOs from the beginning.
