Insert all four filament tubes into the print head filament hub.
Pass all four filament tubes through the cable holder.
Use cable organizer to secure the cable.

Install ACE Pro - Step 2

Insert the 6-pin end of the cable into the hole on the left corner of ACE Pro, Note that the cable buckle faces outward.
Remove the four blue retainers at the filament tube connection port.
Insert all four filament tubes into the filament tube connection ports of the ACE Pro (Note: filament tubes are matched in no order).
After completing the above operations, install the four blue retainers back to their original positions.

Check Before Use

Pulley elastic adjustment
Check if the print head is shaking. If it is, adjust the hexagonal isolation column located underneath the print head until it slides smoothly and without shaking.

Check if the print bed is shaking. If it is, adjust the hexagonal isolation column located underneath slides smoothly and without shaking.
Belts
Please manually move the print head and print platform. If there is any difficulty or abnormal noise during the movement, adjust the tensioner to ensure smooth sliding of the print head or platform.
Connecting to Power
Connect the printer and ACE Pro to power outlet with the power cable, then power on the printer.

caution Note:

When inserting the power cord, please avoid crossing it with the print head cable to prevent interference.
Before turning on the power, please check the printer power level matches the local voltage.

Loading Filament

Place at least one roll of filament in ACE Pro.
Insert one end of the filament into the filament inlet, and ACE Pro will automatically pre-load the filament after detecting it.
Press the [Filament) interface, click to select a filament, and then edit mark will appear. Select the corresponding and color and click save, lf you use Anycubic RFID filament, the filament color and material will be automatically
After completing the above operations, click (Extrude), wait for the nozzle to heat to the preset temperature, filament will be extruded from the nozzle.

Printer Binding

Please connect the printer to the network first.
Scan the QR code on the Printer screen, QR code path: ( Settings) - (Cloud), download the ANYCUBIC App, register and log in to the ANYCUBIC account.
Open ANYCUBIC App, click [+intiate printing], click [Scan],and scan the QR code on the Printer screen to bind ANYCUBIC account.

Open the attached USB Drive and navigate into the path:\FiIes_EngIish_Anycubic Kobra 3 combo\Anycubic Slicer \Anycubic Slicer _ Usage Instructions

After the software installation is completed, enter the main interface and click (Workbench) or (Log in to begin remote print)
lf you already have an APP account, you can directly enter your account and password to log in. If not, click [Sign Up Now].
Click (Add Printer)
Automatically find printers on the same LAN as the current device. If the APP has been bound to the machine and logged in to the same account, the information will be automatically synchronized
Select the machine that needs to be bound in the automatic search results and click (Add Now] Multiple printers can be connected; if the search is not successful, please click (Connect with device CN code) Or [connect with APPI
If the search fails, enter the CN code of the device to connect. Find the CN code path: Select [Settings-Cloud Platform -More Information) on the printer You can view the CN code

caution Note: The software interface is subject to the latest version

First print

Select a model from the local or U-DISK and start printing. *We recommend using one Of the pre-loaded files as a first test print.

Note : The built-in model is subject to reality

Other Function Descriptions

Vibration Compensation: To achieve better printing results, it is recommended to perform a vibration compensation check after printing for more than 300 hours or when the machine has been moved. This feature helps reduce the occurrence of banding during high-speed printing. Regular vibration compensation checks help maintain the stability and accuracy of the printer, thereby improving print quality.
Press "Tools" - "Control" - "Vibration compensation" and wait for the machine to complete the calibration. Please do not touch the machine during the calibration process.

Filament Runout Detection: This function is designed to prevent printing failures when the filament runs out during the middle of a print. It alerts the user to replace the filament before continuing the print, effectively preventing wasted prints due to filament shortage.

Power Loss Resume:when printing using the filament holder, in the event of a sudden power outage or accidentally turning off the machine, this function does not require manual setup. Simply reconnect the power and turn on the machine. You can then resume the print.

caution Note:
ACE pro currently does not have the function of power loss resume

Leveling

Press "Tools" - "Control" - "Auto Level". Wait for the machine to complete the leveling process.

caution Note: Please check whether the PEI magnetic spring board is installed before leveling.

Maintenance Recommendation

Z-axis Lead Screws
*The Z-axis lead screw needs regular lubrication, as proper lubrication ensures smooth movement.lt is recommended to perform maintenance every three months.
Before applying lubricating grease to the Z-axis lead screws, it is important to clean them thoroughly, removing any dust or plastic particles. Then, using the axis movement controls, move the print head to a higher position. Apply a thin coat Of lubricating grease on the Z-axis lead screws, and then home the printer again.
You can repeat this movement process a few times to ensure the grease is evenly distributed over the Z-axis lead screws. Once completed, clean off any excess lubricating grease that may have accumulated near the lead screw nuts.
Maintenance Recommendation - Part 1

X/ Y-axis double metal spindles
*The X/ Y-axis double metal spindles require regular lubrication, as proper lubrication ensures smooth movement.lt is recommended to perform maintenance once a month.
Before applying lubricating grease to the X/ Y-axis double metal spindles, it is important to clean them thoroughly, removing any dust or plastic particles. Then, apply a thin coat Of lubricating grease on the X/ Y-axis double metal spindles and home the printer. You can repeat the movement process a few times to ensure the grease is evenly spread over the X/Y-axis double metal spindles.
Maintenance Recommendation - Part 2

*Please scan the QR code for more maintenance information.

Hotend replacement

Before replacing the hotend, please cool down the nozzle first, click [Tools] - [Preheat] - [Cooling], wait for the nozzle temperature to drop below 40 degrees, and turn off the printer.
Press both sides of the print head lightly and pull the print head front cover forward to remove it.
Gently pull the bottom black and white lines forward to remove them.

Pull the retaining spring forward to loosen the hotend.
Insert the new hotend upwards to the very bottom, and note that the white wire is at the front.
Press the retaining spring back to fix the hot end.
Plug the two wires back to their original positions, and note that the black wire is at the bottom.
After completing the above operations, close the front cover to complete the hot end replacement.
