Describe your issue:

…Hello everyone😊 I’m new to the forum and needed help with Klipper.
My 3D printer is a Kobra2 Neo, and I’ve already configured Klipper. I’m using the ready-made Printer.cfg and macros from this forum. I don’t know what I’m doing wrong, but my first layer keeps changing. Sometimes it’s too high, sometimes too low. I don’t have this problem with the original firmware; once the Z offset and bed leveling are done, everything works perfectly. I have a few questions:

  1. Probe_calibrate at room temperature?
  2. Bed mesh before or after? (At print temperature or at room temperature)
  3. How long should I preheat the print bed before printing?

Can someone help me with the calibration up to the first layer so I can get this under control? I’m reluctant to go back to the original firmware because I really like Klipper.
