  • Page 22: Check Before Use

    Check Before Use 1. D-shape wheels D-shape wheels of the base and print head may be loose due to transportation. After assembly, place the printer on a flat desktop and check the wheels. ① X axis: Shake the print head manually. If it wobbles, tighten the wheel by rotating the eccentric nut with an open-end wrench until the print head does not wobble and moves smoothly along X axis.
  • Page 23 Check Before Use ② Rotating the eccentric nuts with an open-end wrench until the wheels no longer turn freely and move smoothly along Z axis. ③ Tighten the screws after adjusting the wheels. ③ Y axis: Shake the printing platform manually. If it wobbles, tighten the two wheels by rotating the eccentric nuts with an open-end wrench until the platform does not wobble and moves smoothly along Y axis.

  • Page 25: Leveling

    Once leveled, it is not necessary to level every time before each printing. Anycubic Kobra supports auto-leveling, which is easy to level the platform. * Before leveling, please ensure that the platform and nozzle are clean and free of foreign matters to avoid affecting the leveling effect.
  • Page 26 Leveling 2. Before leveling, use a metal tool such as the included wrench to touch the proximity switch and the indicator will light. If the indicator still does not light after repeated touching, please contact the after-sales service. 3. Return to main menu, click Prepare → Leveling → Auto-leveling→ OK on the pop-up interface.
  • Page 27 Leveling 4. After probing the platform, put a piece of paper onto the platform, click Z offset → ＋ or — to adjust the Z-axis height until the nozzle touches the paper (feel slight drag resistance when pull the paper), then click OK .

  • Page 28: Loading Filament

    Loading Filament 1. Return to main menu, click Tools → Move Axis , click continuously to rise the print head, so that there is enough space for loading. 2. Return to main menu, click Prepare → Filament → Filament In, and the heating up interface will pop up, click “OK”.
  • Page 29 Loading Filament 3. Cut the end of the filament at a 45 degree angle and straighten the filament, then place the filament spool on the filament holder.
  • Page 30 Loading Filament 4. Check the temperature on the screen. When the nozzle reaches the target temperature, click “Filament In” again. Press the extruder handle and insert filament into filament intake until the filament is fed by the extruder and melted through the nozzle.
  • Page 31 Loading Filament Supplement: During feeding, if the extruded filament is not smooth or too thin, please adjust the extrusion force by rotating the knob as shown below. Loosen Tighten • If the filament is not extruded or extrusion is not smooth, please increase the extrusion force by tightening the knob.

  • Page 32: Printing Models

    Printing Models After the leveling and filament feeding are completed, the printing can be started. A printable file "owl.gcode" has been preloaded in the memory card and the users can print it directly. * In order to let the printer better recognize the GCode file in the memory card, you need to back up all the files in the memory card to the computer, and keep the memory card only for the GCode files.

  • Page 34 Printing Models The printing effect ① and ③ can be improved by adjust Z-offset during printing. How to adjust the Z-offset: Click Settings on printing status interface, then click “＋” or “—” of the Z- offset to adjust the distance between nozzle and printing platform and observe the printing effect.
  • Page 35 Printing Models Please adjust the Z-offset patiently until the effect likes ②. If the printing effect is still not good after multiple adjustments, please stop printing and level the platform again. The nozzle and heated bed are still at a high temperature when printing is finished.

  • Page 36: Removing Filament

    Removing filament 1. Return to main menu, click Tools → Move Axis , click continuously to rise the print head, so that there is enough space between the nozzle and platform. 2. Return to main menu, click Prepare → Filament → Filament Remove, and the heating up interface will pop up, click “OK”.
  • Page 37 Removing filament 3. Check the temperature on the screen. When the nozzle reaches the target temperature, click Filament Remove again. The extruder will extrude a few filament first and then retract it to the gear. You need to pull out the filament in time to avoid clogging.
