I am finally reaching out as I am at my wits end and need experienced people to help me resolve my printing issue.

I have a Voxelabs Aquila (Ender 3 v2) formerly running marlin with small but manageable annoyances like overhang and manual bed leveling and thus began my journey after a year of using Aquila to start modding/upgrading the thing.

First thing i did was upgrade the fans and shroud, this improved prints slightly but was still not satisfied.

Moved to Klipper and added BLTouch and this is where all my problems started. After hours of following guides and troubleshooting of setting them both up, i still get very little bed adhesion and layers are not smooth together (gaps) with the same 3d slicing software i have been using before the switch (yes changed it to Klipper firmware in slicer)

As you can see in the picture this is after a manual bed level. Where do i go from here?

Edit 2: fully cleaned nozzle, hotend, and bed without any other changes with same results.

Edit 1: forgot to add my printer.cfg

    Before going any further to adjust your Z offset and other factors to tune for better bed adhesion, you should probably adjust your bed to actually be level as well as ensure (seeing that you only have one z lead screw?) that the X axis frame isn’t sagging on the side not containing your Z lead screw. Once you’ve got those factors sorted out, you should check your probe repeatability and then set your Z offset accordingly.

    Bed adhesion even with proper, clean first layers can be a pain depending on the bed surface, material being printed, how clean the bed is of oils and other contaminants, how hot the material is being extruded, and how hot the bed is among other factors. While using a bed mesh will greatly help to account for off-zero unevenness in your bed surface, you really shouldn’t use it to compensate for uneven bed leveling (especially when it looks like you are nearing more than 0.5 mm in unevenness).

    To diagnose other print issues, it will be helpful to see a picture showcasing the problems described in a failed print.

    As a side note, it is somewhat difficult to read your Klipper config file without using view source as it is being markdown formatted. You can negate it by using three graves on the lines above and below it so that it is wrapped in a ‘code block’ and isn’t formatted.

    ```
    Some code
      eeeee
      fffff
    ```

    Turns into

    Some code

      Thanks, i have updated my post with proper markdown sorry about that. I will level it again and increase the z offset to flatten the print for better adhesion (while i have done this before wouldnt hurt to do it again)
