Check Before Use

1. 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 the print bed until it slides smoothly and without shaking.
   Similarly, the pulleys on both sides of the gantry frame can also be adjusted.
2. Belts
   Please manually move the printhead and print platform. If there is any difficulty or abnormal noise during the movement, adjust the tensioner to ensure smooth sliding of the printhead or platform.
3. Connecting to Power
   Connect the printer and ACE Pro to power outlet with the power cable, then power the printer. Note:
   1.When inserting the power cord, please avoid crossing it with the print head cable to prevent interference.

Loading Filament

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

Note:

1. Before inserting the filament into the filament inlet, make sure to straighten the end of the filament.
2. It is recommended to use plastic filament trays first to achieve better printing smoothness. If you use p aper trays, the tray may slip and produce debris due to friction. It is recommended to use it with an adapter ring. (Please download the adapter ring from Makeronline)

Printer Binding

1. Please connect the printer to the network first.
2. 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.

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.
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. 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. It 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 leadscrew nuts.
X/Y-axis double metal spindles
*The X/Y-axis double metal spindles require regular lubrication, as proper lubrication ensures smooth movement. It 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.
