3d printing calibration suggestions

[pauserratgutierrez]

Printed this in a Snampaker 2.0 a250 using PLA after doing a 5x5 point calibration from the display (max calibration mesh from display).

It's easy to see that something is wrong, some areas of the model present an extremely low nozzle, others the nozzle to high and other areas relatively ok in comparison to the others. Some filament isn't sticking to the bed while some is super sticky and even not extruded because of the nozzle almost hitting the surface.

After doing a G-Code 11x11 calibration from Luban Console using macros the results were much better.

• First macro for 11 point auto calibration:

  G28 ;Home
  G1029 P11 ;Set auto-level mesh to 11x11
  G1029 S ;Save auto-level mesh configuration
  G1029 A ;Start auto-leveling

(Once the Snapmaker stopped taking measurements I used the Z up/down console in Luban because it allows movements in increments of 0.02mm (Suggestion: add 0,02mm movements to screen calibration too))

• Then executed this second macro:

  Auto-Level Finish (set Z-offset first)
  G1029 S ;Save settings
  G1029 D0 ;Confirm auto-leveling is on.
  M420 V ;Verify auto-level results
  G28 ;Home

And the result I got after running this Macros and doing the same G-Code as before:

So why don't you include bigger mesh calibration? We don't mind having to wait a long for it to calibrate as long as results present an overall better print quality and first layers are better. I suggest adding 11 point calibration to the display (and even more) so we can do 1x1, 3x3, 5x5 and 11x11. It would be great if speed is incremented too so calibration is faster.

I'm surprised that your bed is in that bad condition, but I agree that having this change to the software would be quite useful.
