Bed Compensates Too much

Hello all. Recently I notice that my printer mesh and the Z are compensating too much. As you can see on the mesh. There are high and low points. On the highest point, the printhead is far from bed and vice versa. Which makes me confused how does the software behaved. FYI: I use LDO 42STH48-2504AC SpeedyPower for 6 steppers.

well for one thing, it appears you 'mesh grid' size is set way smaller than your bed size. So in combination with the dimensions of your Z screw positions, the mesh is compressing/exaggerating the scaling. for a VC400 you should be doing a mesh larger than you have set. Might I suggest testing a mesh min/max of 50,50 and 350,350 and re-run your mesh grid of around 9,9 points

Hi. Thank you for reaching out. The picture is using KAMP so it may not exactly represent for what happening now. For normal, bicubic 7x7 Mesh. The same problem arise.

so i have tyo ask...why KAMP? ...as the auto mesh for the space where you are printing built into RatOS works perfectly.

So I was trying to use a different method to provide that the software behavior is acting falsely, but I do have a look at the document and I found out about the bicubic tensions I think is overshooting the parameters At first, I thought the RatOS would work perfectly and that is undeniable, but through the process of using, it kind a hassle when you come to bed mesh

did you change your bicubic tensions ? technically a higher res mesh should have fixed ur issue like 10x10

I fixed my issue It was a mesh issue As exoected But a probe one mainly
