Auto Bed Levelling Isn't correcting Enough
Hello, i build a „normal“ 3d Printer (no Delta) and have trouble with the auto bed levelling.
First I’m using a wood Bed with Double-sided adhesive tape without bed levelling. That works more or less fine for the first test runs.
Now I buy a proper bed with blue Tape on it and enable auto bed levelling and attached a reflection light sensor to the Z-Axis. After that a reflection Laser sensor and then a normal switch.
Then I’m using
M321
M322
G28
G0 X124 Y167 Z30
G32
M320 S2
At the end, the Z-Axis is moving wen the X- and Y-Axis are moving.so far so good now I have the issue that the Z-Axis is not moving enough.
On the 4 corners the high is perfect, but on the middle of the bed, the nozzle is over 0.5mm to high.
My Bed is ok but the Y-Axis has Construction-related a curve J
Now the question what can I still do?

this is my first forum post on English so Excuses this.

Thangs for that advice.
After enabling distortion correction and correcting the x and y coordinates on my Printer´s firmware hi is testing the grid and give me some output on the console, but when I move the x and y Axes the Z Axes do´s nothing.

If you set the DISTORTION_END_HEIGHT at 0 it is normal that hi is do´s nothin.
Now it is working just fine. thank you again for the help.
