IRA3D

imamo IRA3d printer. Za modeliranje uporabljam FreeCAD, za slicer pa CURA

CURA nastavitve printerja:

X(Width): 250mm Y(Width): 250mm Z(Width): 300mm

Build plate shape: Rectangular Heated bed: [x]

G-code flavor: Marlin

G-CODE (Marlin)

First created in 2011 for RepRap and Ultimaker by Erik van der Zalm et. al., today Marlin drives most of the world’s 3D printers. Reliable and precise, Marlin delivers outstanding print quality while keeping you in full control of the process.

Horizontal expansion

Ker se filament nekoliko bolj razleze na samih robovih objekta, je potrebno to upoštevati, če želimo doseči točne mere printanja. V CURA-i to nastavimo s parametrom

Shell
  [x] Horizontal expansion
  [x] Initial Layer horizontal expansion

Pri printerju IRA3d je bilo to potrebno nastaviti na ‘0.15mm’, ker so bile luknje za cca 0.3mm prevelike.

Pomik koračnih motorjev

Printtanje kvadra dimenzij 140x5x5 mm Naprintan: 139.2mm x 4.94mm x 5.18 mm 140mm … 139.2mm x ……. 78.74 s/mm * 140mm = 11023.6 stps Naredil je 11023.6 korakov, moral bi jih pa več = > 79.1925 steps/mm

M92 X79.19 Y79.19 Z800.00 E828.78

to naj bi blo flov na 95% in višina mal manjša

M92 X79.19 Y79.19 Z793.65 E746.00

mislim, da bi bilo potrebno korak še malo šovečat, ker se kar precej skrči… mogoče na X80 Y80 Z792 E746
