Delta Mesh Bed Sine Wave?

veryevil

Hi, I've run mesh bed compensation on my newly converted Anycubic Linear Plus Delta and I get a sine wave for my bed. I assume this means there is an issue or imbalance with one of the M665 or M666 params as its too uniform to be coincidence. I'n using the Ultrabase glass bed so doubt its that which is this shape.

Here is the height map
heightmap.csv

My params look like this:
; Delta parameters
M665 L269.338:269.338:269.338 R134.440 H292.563 B105.0 X-0.817 Y-0.011 Z0.000
M666 X-1.765 Y3.610 Z-1.845 A2.29 B-1.92

Any help would be appreciated

Thanks

My guess is that you are using an offset Z probe, and the tilt of the effector is varying slightly with XY position.

what factor calibration did you do?

I used 9 Factor with 12 points.

I am using on offset micro-switch probe. Its about 17.8mm down directly under the nozzle when attached.
