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 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

optional:

( #if ANYCUBIC_PROBE_VERSION == 2
#define NOZZLE_TO_PROBE_OFFSET { 0, 0, -15.10 }
)

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 15.10 )
• 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'

TPU

Generally not enjoyable with bowden-type extruders. Buy another printer.

Print and mount the extruder mod, otherwise the filament will jam between the extruder gear and the Ptfe-tube.

Print slowly, not too small layer height, reduce retraction distance as it won't work anyways. Disable fan, disable heated bed.

Avoid models that require many travel moves.

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

LEDs (WS2812)

print rails

and connect the led-strip to the trigorilla board at D11, +5V and GND

if you connect more than a few leds, a step-down converter is needed! don't supply them via the trigorilla's 5V rail.

In the Marlin/Configuration.h uncomment: #define NEOPIXEL_LED #define NEOPIXEL_TYPE NEO_GRB + NEO_KHZ800 #define NEOPIXEL_PIN 11 #define NEOPIXEL_PIXELS 35

In the Marlin/Configuration_adv.h uncomment: #define LED_CONTROL_MENU
