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 Run out 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.

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 lead screw 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. 

Hotend replacement

1. 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.
2. Press both sides of the print head lightly and pull the print head front cover forward to remove it.
3. Gently pull the bottom black and white lines forward to remove them.
4. Pull the retaining spring forward to loosen the hotend.
5. Insert the new hotend upwards to the very bottom, and note that the white wire is at the front.
