Weird height map - BLTouch
Zest last edited by
I finally got my machine running and I'm ALMOST there with the mesh leveling. I can get it to probe 25 points but the resulting map is obviously not right.
Here are my bed.g and config.g files. I copied most of the important bits from the other threads. The result I get is from clicking the bed compensation button in the GUI. I know I'm missing something obvious but I have no idea what it is.
The printer is a wanhao I3 with a 190x200 bed. I think it has something to do with the grid… Also the deviation between points seems awfully high.

1. Is the print bed level?
2. If you have dual Z motors, are they both moving when the bed is being probed?

I had a result like that because I didn't run G32 first.
