Anycubic Kossel Plus

Set-up guide and related things for the Anycubic Kossel Linear Plus 3D Printer.

Getting started

Build Marlin

• Marlin Repository
• Instructions for Anycubic Kossel

git clone https://github.com/MarlinFirmware/Marlin.git -b bugfix-2.0.x
cd Marlin
cp config/examples/delta/Anycubic/Kossel/Configuration.h Marlin/
cp config/examples/delta/Anycubic/Kossel/Configuration_adv.h Marlin/

Adjust the Marlin/Configuration.h for your model:

#define ANYCUBIC_KOSSEL_PLUS #define ANYCUBIC_PROBE_VERSION 2 #define ANYCUBIC_KOSSEL_ENABLE_BED 1

( #if ANYCUBIC_PROBE_VERSION == 2 #define NOZZLE_TO_PROBE_OFFSET { 0, 0, -15.00 } )

virtualenv -p python --no-site-packages .
source bin/activate
pip install -U platformio
pio run
pio run --target upload

Set up the 3d printer

• Configuration > Advanced Settings > Initialize EEPROM
• Configuration > Delta Calibration > Set Delta Height ( G33 P1 )
• Configuration > Delta Configuration > Probe Z-offset ( Set manually to 15.00 )
• Configuration > Delta Calibration > Set Delta Height ( G33 P1 )
• connect the Z-Probe and start Configuration > Delta Calibration > Auto Calibration
• Configuration > Delta Calibration > Store Settings
• Motion > Bed Leveling > Level bed followed by Store Settings

use Configuration > Advanced Settings > Probe Z Offset to correct the difference and execute the calibration again

optional: tune PID

Nozzle

(DEFAULT_Kp 22.36 DEFAULT_Ki 1.63 DEFAULT_Kd 76.48)

• run the following G-Code (e.g. in Proterface) with the nozzle cold: 'M106 S255' & 'M303 E0 C10 S200'
• store measured values: 'M301 P17.96 I1.44 D55.90'

Bed

(DEFAULT_bedKp 374.03 DEFAULT_bedKi 72.47 DEFAULT_bedKd 482.59)

• run 'M303 E-1 C8 S60'

• store measured values: 'M304 P254.09 I44.31 D971.39'

store values in eeprom:

'M500'

Plotting

use Inkscape and the included Gcodetools. A 3d-printable pen holder (to use with rubber-bands) is attached in the addons/ folder.

Prepare Image

• Make sure to have everything on a single layer
• At the top bar leave units at px but treat them as mm!
• scale object to desired size
• Path -> Object to Path
• Path -> Combine
• Path -> Union
• View -> Display mode -> Outline to preview
• if there are too many nodes: Path -> Simplify

Gcodetools

• Extensions -> Gcodetools -> Tools library... select default tool

  • Diameter: 1.0
  • Feed: 2400
  • Penetration feed: 2400
  • Passing feed: 3600
  • Depth step: 1.0

• Extensions -> Gcodetools -> Orientation points

  • 2-points mode
  • Z surface: 0.0
  • Z depth: -1.0

• move to center of object (0,0 is center of print-bed) and a bit to the right, as the pen is mounted right from the effector (45mm)

• select object

• `Extensions -> Gcodetools -> Path to Gcode

  • Offset along Z axis: 11.0
  • Z safe height for G00 move over blank: 3.0
  • Units: mm

Print

• home printer
• print

Experimental Cura settings:

Layer Height: 10 mm Initial Layer Height: 10 mm Wall Line Count: 1 Top/Bottom Thickness: 10 mm Print Thin Walls: True Infill Density: 0 % Default Printing Temperature: 0 °C Build Plate Temperature: 0 °C Enable Retraction: True Retraction Minimum Travel: 2 mm Combing Mode: off Z Hop When Retracted: True Z Hop Height: 2 mm Enable Print Cooling: False Generate Support: False Build Plate Adhesion Type: none Slicing Tolerance: Inclusive Maximum Resolution: 0.2 mm
