PRUSA Profiles for AnyCubic Kobra Max
The extrusion mutiplier for these profiles is based on a 100mm feed. My stock Kobra Max had the extrusion eSteps set to 95%. The stock value on my Max was 405. When I calibrated it I ended up with 419.88
You can change the eSteps easily with PRONTERFACE by issuing an M92 E###.## GCODE and then sending an M500 to save the new value in EPROM. To see the stock value use PRONTERFACE and send an M503 GCODE. Then look for the following line:
M92 X80.00 Y80.00 Z400.00 E405.00
If you don't change the eSteps, keep in mind the Extrusion Multiplier could be 5% less.
All profiles created with PRUSA SLICER 2.5.0: https://github.com/prusa3d/PrusaSlicer/releases/tag/version_2.5.0
To use the profiles, select the green "CODE" button --> Download Zip. Save to your hard drive and then unzip. In PRUSA Slicer: File --> Import --> Import Config and select the config.ini you want.
For the bed:
These are the graphic and STL files for the Chiron Bed that can be used in PRUSA Slicer
To use them move them to are place where they won't get lost or replaced on your hard drive. Run PRUSA Slicer - Printer Settings --> General --> Bed Shape --> Set In the dialog window, Load Texture and select the PNG file Select Load Model and select the STL for the bed.
Note the bed is only partially transparent.
Various brands of filaments were used in testing these profiles. The profile where the temperature is heavily dependant on the brand is TPU. I tested with SainSmart and ERYONE. They print fine at the profile temperature. However with Overture, it needs to be a lot hotter, as in the 218C range.
ABS: PRUSA, kexcelled
PETG: Filaments.ca, ERYONE, Polymaker, GEEETech
PLA: ERYONE, eSun, 3D Solutech, Quantum 3D
TPU: SainSmart, 3D Solutech, ERYONE, Overture (needs higher temp)
HIPS: 3D Printing Canada
The SVG and STL are the custom graphic/model for the bed. Put them in a folder where they own move and then in Printer Settings-->General-->Bed Shape, you can select the two files.
Sept 9 - 2022 - Added DRAFT print profile, created with PRUSA Slicer 2.5.0. Layer height 0.3, fast printing speed, uses volumetric Pressure Equaliizer. To use select the draft prifle, then for the Filament and Printer settings select the filament type you want to use. Hence the DRAFT profile (print settings only) is generic for all filaments. For the higher speed and thicker layer height, you may need to increase the hot end temperature by 5%. Do not recomend draft profile for TPU.
