Before assembly, use pliers and other tools to remove zip ties and wrapping materials. It is suggested to use a flat desktop and place the parts in an orderly manner for quick assembly.

1. Install frame:

(1) Use pliers to cut the zip ties. Fix the frame to the base using 4 pieces of M5*25 screws and spring washers. Fasten the screws after all screws are pre-installed.

(2) Install the T plates on both sides of the frame. Note the direction of the T nut in the Aluminum profile.

2. Install display:

Remove the M4*8 screws holding the display to the base. Move the display from the front to the side and secure it using the same screws and nuts.

3. Wiring:

(1) Insert the cables into the corresponding ports by the color code.

(2) Move the platform to the front, and then insert the Z limit switch wires and the Z axis motor wires into the corresponding ports on both sides of the machine. Keep the wires in place with zip ties and ensure they do not interfere with bed movement.

4. Install filament holder and filament:

(1) Use two M3*5 screws to install the filament holder. Then, use two pairs of M4*8 screws and T nuts to install the filament holder to the base, about 140mm from the rear.

(2) Select the correct voltage mode (110V or 220V) according to your local ratings. The switch is inside the power supply and 220V is the default. Use hex keys to move the switch. Double-check the wiring, plug in the power cord, and switch on the printer.

(3) Place the filament on the filament holder, noting the feeding direction of the spool.

5. Install filament:

(1) Click “Tools” -> “Filament” -> “Filament in”, and a pop-up window will appear. Click “OK”.

(2) Straighten the end of the filament, pass it through the filament sensor, then press the handle on the extruder and push the filament in until it just reaches the white Teflon tubing.

(3) During waiting, manually slide the print head to the left. When the target temperature (e.g., 230°C) is reached, click “Filament in” again. The extruder will automatically feed the filament, which will melt through the nozzle. Click “Stop” on the screen and use tweezers to clean the filament residue from the nozzle.

Step 1. Enter Manual Leveling Mode:

Insert the memory card. On the Home Menu, click “Print”, choose the file “Manual_Leveling.gcode” and print it. This sets the machine to manual leveling mode. When printing is done, click “OK” and return to the Home Menu.

Step 2. Home the Z-axis:

Manually move the print head to the far left side until it touches the X limit switch. Then, click “Tools” -> “Home” -> “Home Z”.

Step 3. Prepare for leveling:

If the printer has been used before, clean any residue from the nozzle with tweezers. Place a piece of A4 paper on the print platform. Manually move the print head and platform back and forth to position the print head over the four corner points and the center spot one by one. Avoid the nozzle rubbing against the platform directly without the paper in-between.

Step 4. Adjust the platform height:

When the nozzle is at a leveling point (e.g., point ①), press the platform and support plate together and manually adjust the corresponding nut underneath. Loosening the nut (clockwise) raises the platform. Tightening the nut (counter-clockwise) lowers the platform.

The goal is to adjust the distance between the nozzle and platform to be about the thickness of the paper (~0.1-0.2mm). You should feel a slight drag resistance when pulling the paper. This means the paper can be moved, but with some resistance. Repeat this for all five points. Perform a double-check in a diagonal order (①->③, then ②->④) to ensure accuracy.

Step 5. Test print:

On the Home Menu, click “Print”, select “LEVEL_TEST.gcode” and click “PRINT” to verify the leveling results. You may need to perform fine adjustments a few times to achieve the best results.

Step 1. Cool down the nozzle:

If the nozzle is hot, it is highly recommended to cool it down first to avoid burns. Click “Tools” -> “Cooling” on the screen and wait until the temperature drops below 60°C.

Step 2. Enter Auto Leveling Mode:

On the Home menu, click “Print”, then choose and print “Auto_Leveling.gcode” to set the machine to Assisted Auto Leveling mode. Click “OK” after printing is done.

Step 3. Install the leveling module:

Click “Tools” -> “Home” -> “Home All”. Then, install the leveling module. The signal line connects to the port on top of the print head, and the sensor is magnetically attached to the steel block on the print head.

Step 4. Start probing:

Return to the Home Menu, click “Tools” -> “More” -> “Level” -> “PROBE”. Ensure the leveling sensor is installed firmly and properly before clicking “OK”.

Step 5. Remove the sensor and test:

The machine will home all axes and probe 25 spots on the platform. After probing is complete and before clicking ‘OK’, you must remove the leveling sensor to prevent damage during the test print. After removing it, click “OK”.

Step 6. Test print and fine adjustment:

The default nozzle offset is set a few millimeters higher to prevent nozzle rubbing. You must fine-tune it. Choose and print the “LEVEL_TEST.gcode”. During the test print, you can adjust the nozzle height.

After starting the “LEVEL_TEST.gcode”, observe the first layer. There are three possible outcomes:

• A – Nozzle too high: There are large gaps between the printed lines, and the filament does not adhere well to the platform.

• B – Nozzle too close: There is a lack of extrusion, and the nozzle rubs against the platform.

• C – Proper nozzle height: The extrusion is good, and the filament adheres well, creating a smooth first layer.

To make adjustments during the test print, return to the Home Menu and navigate to: “Tools” -> “More” -> “Level” -> “ADVANCE SETTING”.

In the “Advance setting” menu:

• To lower the nozzle (if it’s too high), select the desired spots on the grid (or click “ALL”) and click the “-” button. Each click lowers the nozzle by 0.05mm. Do not press continuously.

• To raise the nozzle (if it’s too close), select the spots and click the “+” button. Each click raises the nozzle by 0.05mm. Do not press continuously.

After each adjustment, you must click “OK” to confirm the modification, otherwise the change will be invalid. Please wait for the current command buffer to finish before the new setting takes effect.

VERY IMPORTANT:

• It is strongly suggested to use “LEVEL_TEST.gcode” for testing.

• Click “-” or “+” only once at a time to avoid hitting the print platform.

• Because the default offset is high, it is initially OK to click “-” a few more times without waiting.

• If the nozzle hits the platform, turn the printer off immediately. You can then restart the Assisted Auto Leveling process.

• If the nozzle hits the platform at the very start of the print, turn the printer off and on, go to “ADVANCED SETTING” to increase the parameters by 2-4mm for all spots, and then try the test print again.

• The “ADVANCE SETTING” is only functional in “Assisted Auto Leveling” mode, not in “Manual Leveling” mode.

The ANYCUBIC CHIRON has two operational modes: print offline and print online.

Print Offline (Recommended):

This mode uses the memory card and minimizes potential signal noise from a data cable.

1. After setting up your model and parameters in slicing software (like Cura), save the GCode file to the memory card. The file name should only contain English letters, underscores, and spaces.

2. Insert the memory card into the printer.

3. Ensure the platform is leveled.

4. On the display, click “Print”, select your GCode file from the list, and then select “PRINT”. The printer will heat up and begin printing.

Print Online:

This mode prints directly from a PC via a data cable.

1. First, you need to install the CP2102 driver to allow the PC to communicate with the printer. The driver is on the included memory card. To check if it’s installed, connect the printer to your PC, turn it on, and check “Device Manager”. If there is an exclamation mark next to “CP2102 USB to UART Bridge Controller”, it needs to be installed manually.

2. Install slicing software like Cura.

3. In Cura, go to “Machine” -> “Machine settings” and select the same Serial (COM) Port that is shown in your PC’s Device Manager.

4. After setting all parameters in Cura, go to “File” -> “Print”. Cura will connect to the printer. Once the “Print” icon is available, click it. The printer will heat up and start printing. Use tweezers to remove any pre-extruded filament from the nozzle tip.

1. Cura Installation:

The Cura software (version 15.04.6 is used as an example) is located on the memory card. Double-click the installer and follow the on-screen instructions. During the first-time run wizard, select your language, then for machine type, choose “Other (Ex: RepRap, MakerBot, Witbox)”. In the next screen, select “Prusa Mendel i3” and finish the setup.

2. Machine Settings:

• Open Cura. Go to the menu bar and select “Machine” -> “Machine settings”.

• Set the machine dimensions: Maximum width (400mm), Maximum depth (400mm), Maximum height (450mm).

• Ensure “Heated bed” is checked.

• For online printing, select the correct Serial port (e.g., COM3) and Baudrate.

3. Slicing Parameter Settings:

You can set parameters in the “Basic”, “Advanced”, and “Expert” settings tabs.

Basic/Advanced PLA Settings (Example):

• Layer height: 0.2 mm

• Shell thickness: 1.2 mm

• Fill Density: 15%

• Print speed: 50 mm/s

• Printing temperature: 195°C

• Bed temperature: 60°C

• Retraction Speed: 60.0 mm/s

• Retraction Distance: 6.0 mm

• Travel speed: 60 mm/s

• Filament Diameter: 1.75 mm

• Nozzle size: 0.4 mm

Explanation of Key Parameters:

• Layer height: Determines print quality, usually 0.1-0.3mm.

• Shell thickness: Should be a multiple of the nozzle diameter.

• Fill density: The higher the parameter, the more solid the model.

• Print speed: 50mm/s is suggested to avoid shaking.

• Printing temperature: PLA is 190-210°C, ABS is 230-240°C, TPU is 190-220°C.

• Retraction: Reduces stringing, but setting it too high can cause clogging.

• Travel speed: 60mm/s is suggested; too fast can affect accuracy.

Users may need to fine-tune these parameters for the best results based on filament type and model complexity.

1. If the filament breaks or runs out during a print, the ANYCUBIC CHIRON will alarm and pause the print. A message “Lack of filament or filament monitor abnormal” will appear on the screen.

2. Click “OK” on the screen. Remove the remaining filament by pressing the handle on the extruder, pushing the filament in until it just melts, then pulling it out quickly.

3. Re-install the new filament as described in the “Install filament” section.

4. After the new filament is installed, use tweezers to clean any filament residue from the nozzle tip. Then, click “CONTINUE” on the screen. The print will resume from the last position.

The ANYCUBIC CHIRON can resume a print after an accidental power outage. This function is only valid when printing offline from a memory card.

1. Model Placement:

In your slicing software (e.g., Cura), you must place the model at the rear of the platform. This is because during the resume process, the machine will home first, and a model placed in the front could interfere with this movement.

2. Modify start.gcode (First time use only):

For the first time using this feature, you must add “G5” to the start.gcode in your slicing software. In Cura, go to “Start/End-GCode” tab and type “G5” at the end of the start.gcode script. After the first time, G5 will be added automatically.

3. Save and Print:

Save the model as a GCode file to your memory card and start the print from the printer’s display.

4. Resuming after power loss:

If power is lost, the print will stop. When power is restored, go to the “Print” menu, select the unfinished file, and then choose “RESUME”. The machine will home its axes and then continue printing from where it left off.

Note:

• To get a smooth surface at the resume point, use tweezers to carefully remove any excess filament from the nozzle before it continues printing.

• Do not move the Z-axis manually after a power outage, or the resume will be invalid.

• This function is developed based on Cura, and compatibility with other slicing software is not guaranteed.

• A perfect surface finish at the resume point cannot always be guaranteed due to differences in models, filaments, and settings.

1. The corresponding end stop might not be triggering when homing. Check the wirings and inspect for any obstacles by manually moving the corresponding axis.

2. The motor cable may not be connected properly. Check each connection and then inspect the cable routing for any faults.

1. Remove the memory card and insert it into a PC. Open the GCode file with a text editor (e.g., Notepad). If the file contains multiple “ÿ” symbols, the file is corrupted. Try reformatting the memory card to FAT32 format and reloading the GCode file.

2. If the memory card is not readable, ensure the file name does not contain special characters. You may also need to try a different memory card.

3. If the touch screen freezes, reboot the machine and try again.

1. Ensure the nozzle temperature has been set to match the filament type.

2. Check if the filament is tangled on the spool.

3. Ensure there is enough cooling for the hotend.

4. The nozzle may be clogged. Try to replace it or clean it.

5. The Teflon tubing may be tangled, squeezed, or bent, restricting filament movement.

The nozzle or throat tube may not be tightened properly. After allowing the hotend to cool down completely, try to fix or change the component.

1. The print speed for the bottom layer might be too fast. Reduce it to around 20mm/s.

2. Ensure the print platform is clean. Use alcohol if necessary.

3. Check if the bed is properly leveled.

4. Add a brim or raft to the model in your slicing software to increase surface area adhesion.

5. Check that the bed temperature matches the requirements of the filament you are using.

1. Check that the bed temperature matches the requirements for the filament.

2. Check the infill percentage of the GCode. The higher the infill, the more likely the object is to warp.

3. Add a brim or raft to the model in your slicing software.

1. The print head may be moving too fast. Slow down the print speed.

2. Check the X/Y belts and the driving wheels to ensure they are properly installed and tensioned.

3. Grease the rods and check that all nuts and bolts remain tightened.

1. Inspect if the touch screen has been pressed by the metal frame at the edge.

2. Check if the screen has cracks. If so, please contact after-sale service.

This error relates to the hotend’s temperature sensor (thermistor).

1. Check the wiring of the hotend and ensure a good connection.

2. Check if there are any bent pins inside the connector.

1. Check if you have chosen the right machine type in your slicing software.

2. Check if there are any plugins in the slicing software that might be causing interference.

1. Check if the GCode file is corrupted. Try re-slicing the model and saving the file again.

2. Delete any plugins in the GCode file.

3. Use print offline mode (with a memory card) instead of printing online via a data cable, as it is more reliable.
