Uneven first layer

Hi I have a V-Core3 500 and the first layer is always uneven where some parts are much too close to the bed and others are too far away! I have it set up to probe 100 points with and inductive probe and it still won’t work. Any advice is greatly appreciated.

Stupid question, but have you property heat-soak the bed before starting?

yes

It looks too close to the bed everywhere. Are you loading a saved mesh or running a fresh mesh before each print?

Did you run a z-tilt before you meshed? (and do you z-tilt before you print?) 100 points is over the top, that shouldn't be needed

I'm having the exact same problem. Z-tilt is always performed, tried a 10x10 grid on a 500, and yet the first layers vary wildly. I'm attempting to print 50 parts in a batch and the first layers are on average 0,2, but I've measured 0,14 to 0,25+ on the same print (with 10x10 grid), the + being failed parts because they don't stick obviously. So even if your z-offset is too low, it should consistently be so for the entire bed yet yours also seems to change. I'm afraid I am also clueless about a solution.

Yes I run z tilt and a new mesh every print

Are you guys loading the mesh at the start of the print ? variable_bed_mesh_profile: "ratos" In the print.cfg

I have the same problem on 3.1 500 when printing ~500mm long object

The latest release of RatOS from a few days ago pretty much fixed my issues completely. Now z-axis compensates properly according to beacon scan and the ripples and inconsistencies from front to back and left to right are equalized in the first layer.
