bed leveling not working correctly after e-prom clear

dmkmedia

i have the electric sensor on a persia i3 printer and since moving to your firmware the probing only does 3 points on the plate

front left then front right then rear middle.

where before it used to do all 4 corners

now when it prints it's like the bed is slightly too high on the rear right side and when the print starets the right side smears and the left side is ok

In firmware setup in features menu  half way down you need to set

Bed Measuring Method to n * n grid  and set the xy coords for the 4 or more points

dmkmedia

cant see the 4 point or mor bit

Hi.

It's the 'bed levelling grid size' value, sets how many point to probe in the X and Y plane 

dmkmedia

no matter what value i put in there it still tests 3 points 2 at the front one at the back in the middle

Is that image from your setting? Since you have set bed leveling method to n * n grid it shoud use 4x4 points.

Also I hope you are using G32 S2 for autoleveling and not G29 (like in marlin). G29 will always measure 3 points and use average height but is no autoleveling!
