Creality Hi bed mesh range of 0.572 mm — is this normal for a new printer?

Creality Hi Printer

Hi everyone,

I have a relatively new Creality Hi, and I am trying to understand whether my bed mesh is within a normal range or if the print bed may be warped.

After running the automatic bed calibration, Fluidd shows:

  • Mesh range: 0.572 mm

  • Minimum: approximately -0.105 mm

  • Maximum: approximately +0.467 mm

  • Probe grid: 9 × 9 points

The mesh has a noticeable curved shape, with the central area lower and the outer areas higher. I have attached a screenshot of the mesh.

I also performed a full factory reset, including deleting the saved settings, logs and G-code files. After completing the initial setup and recalibrating the printer, the new mesh had almost exactly the same shape and the same 0.572 mm range. This makes me think the result is repeatable and may be caused by the spring steel sheet, magnetic surface or heated bed itself rather than a corrupted calibration.

The printer can still print, but I have noticed a few related symptoms:

  • The nozzle sometimes lightly scrapes the left side of the build plate during the initial purge line.

  • The first layer can look over-compressed, with visible nozzle marks.

  • I currently need an additional positive Z offset of approximately +0.100 mm to obtain a good first layer.

Is a mesh range around 0.57 mm considered normal or acceptable for the Creality Hi?

Is there a recommended way to manually improve or level the bed on this printer, or does this shape indicate that the spring steel sheet or heated bed should be replaced?

I have already checked that:

  • There is no filament or debris under the build plate.

  • The magnetic surface is clean.

  • The nozzle is clean before calibration.

  • The plate is correctly positioned.

  • The same mesh shape returns after recalibration and after a factory reset.

Any advice from other Creality Hi owners would be appreciated. It would also be helpful to know what bed mesh ranges other users are seeing on their machines.

My range is 0.3815 with z offset at exactly 0.

Pictures look almost identical to yours with high spot on the left hand side of the plate.

My left side also shows signs of scoring by the nozzle.

Thanks for sharing this. Your bed mesh looks very similar to mine, especially with the higher area on the left side. I had the same initial scraping on the left side, but I managed to fix it by editing the gcode_macro file.

My NOZCLEAR_START_PRINT macro is now:

[gcode_macro NOZCLEAR_START_PRINT]
gcode:
  G92 E0
  G1 Z3 F600
  M83
  G1 Y100 F12000
  G1 X-2 F12000
  G1 Z0.45 F600
  G1 X-2 Y100 F4000
  G1 X-2 Y-2 E15 F2000
  G1 X60 Y-2 E9 F2000
  M82
  G92 E0

The important line is:

G1 Z0.45 F600

The Z0.45 value controls the nozzle height during the purge line, while F600 is only the movement speed.

I recommend testing different Z values in small increments. If the nozzle is still scraping, increase the Z value slightly, for example from 0.45 to 0.50. If the purge line is too high and does not stick properly, decrease it slightly.

After adjusting this value, my purge line became perfect and the nozzle no longer scratches the plate. This does not fix the bed mesh variation itself, but at least it prevents the initial scraping.
