It does not appear that the leveling and the first layer print are with it. ---

BTW: What are you trying to print with? 100°C for the bad and 250°C for the extruder? ---

I was trying to print with ABS, that’s why I used 250°C for the hotend and 100°C for the bed. Should I change them? ---

Yes, my printer is enclosed. ---

Have you tried to do this with PLA? ---

I tried it with PLA before, but not after the recent changes. I didn’t have this issue when I printed with PLA before. But I don’t think it’s related to the filament. During the print, the nozzle scrapes the bed and vibrates heavily in the areas where the print is failing. ---

If PLA prints fine, then the printer and Klipper work fine. You may check the slicer settings. You also may do the bed leveling at 100°C, as you need it for ABS ---

> [@EddyMI3D](#): > > You also may do the bed leveling at 100°C Did you run your mesh at 100 °C? Is klipper adjusting Z for the wrong bed shape? I’d also adjust the mesh area to exclude the high edge, ![image](https://global.discourse-cdn.com/free1/uploads/klipper/original/3X/c/9/c9edc0b4e828ffd2dd0c2d7d4d345b67b32ddf98.jpeg) I think the high points are “edge effects” and are not accurate. ---

How far should I stay away from the bed edges when defining the mesh area? ---

You can define the limits of the area in the `[bed_mesh]` section :[Configuration reference - Klipper documentation](https://www.klipper3d.org/Config_Reference.html#bed_mesh) ---

Have you already run the bed mesh on 100°C? The surface of a build plate can change significantly in comparison to 70°C ---
