I have been having issues with my first layer and figured I would run a 20x20 mesh to see if I could find any issues with the topology of the bed. I definitely got something interesting but I am not sure what conclusion I should be deriving from this. If anyone has any ideas please let me know because this is my 2nd creality printer but the first time I have seen such a fine mesh have this many “spikes”
Hello Antal_Mak,
That is a weird one isn’t it.
Is it possible that the printer is on a not so stable platform ? it looks like some ringing effect.
This is a long shot (but one I check for at times), is there any grit under the build plate ?
I have found that from taking my build plate away to the kitchen sink to wash it, when I get back sometimes I find specks that need wiping off the heat pad.
Cheers.
Thanks for the quick response. Unfortunately both of those are a now.
- The shelf/desk it is on is built into the wall, no movement there
- I have done the bed leveling procedure a few times with similar results. I have cleaned underneath (I have also had some dust underneath on my older printer in the past). I have tried a different bed, same style just a smooth PEI plate.
It almost seems like the sensor is not performing consistently. Does anyone know of any way I can check the strain sensor? Maybe the front left one is not responding so it thinks it is lower than it actually is?
I did a factory reset and did a full 20x20 mesh again (this time displaying through fluidd) with a similar result.
Here is the mesh and the screenshot. It seems a bit high to be normal variation, 0.1mm variation between 2 points less than 15mm apart.

When you changed the mesh did you put in algorithm: bicubic as lagrange can have issues with a bed mesh of more thatn 6x6
Thanks for asking. The default is bicubic and I just confirmed it’s still bicubic.
