3D spausdintuvo bed leveling optimizavimas

,

:marlin: :3d-printing:

Sureguliavau spausdintuvo bed leveling’ą. Atlikau šiuos darbus:

  1. Nustačiau teisingai leveling probe’o poziciją nozzle’o atžvilgiu.
  2. Panaikinau atstumą tarp probe’o ir kraštų.
  3. Padidinau matavimo taškų skaičių nuo 3x3 iki 5x5
  4. Įjungiau ABL_BILINEAR_SUBDIVISION interpoliaciją, kuri paskaičiuoja dar tris tarpinius taškus tarp matuotųjų.

Su Octave nusibraižiau paviršių, kad pažiūrėt kaip atrodo. Pvz.:

a1 = [-0.830,-0.083,+0.496;
-0.617,+0.083,+0.578;
-0.716,-0.325,-0.172]
