🚨 Important Screw Check:

The base locking screws must be fully tightened. Loose screws may cause the device to move unevenly during operation, interfering with the Y-axis and leading to skipped steps or abnormal movement. If motion errors occur during subsequent printing, please return to this step to check the screws first.

Step 8: Lubricate the Y-axis Guide Rails

  • Take out the lubricant from the accessory box.

    Take out the special lubricant bottle

⚠️ Note:

During maintenance, always use "lubricating oil". Strictly prohibit the use of thick "lubricating grease", otherwise it may cause damage to the transmission structure.

  • Apply a small amount of lubricant to the upper edge of the Y-axis guide rail (on the steel shaft).

    Apply an appropriate amount of lubricant to the upper edge of the steel shaft rail
  • Use the tail end of the lubricant tube to evenly spread the lubricant on the curved surface of the guide rail (on the steel shaft).

    Evenly spread lubricant over the surface of the steel shaft
  • Push the heatbed to the rear.

    Push the heatbed platform to the rearmost position
  • Lubricate the steel shaft at the front of the printer.

    Lubricate the exposed steel shaft guide rail at the front
  • Use the tail end of the lubricant tube to evenly spread the lubricant on the curved surface of the guide rail (on the steel shaft).

    Spread the oil evenly over the front guide rail surface
  • Move the heatbed back and forth to evenly distribute the lubricant.

    Manually push the slider back and forth to fully seal the lubricant

Step 9: Install the Y-axis Top Cover

  • Push the heatbed to the middle.

    Heatbed platform centered
  • Align the front snap of the Y-axis top cover with the mounting slot, and gently slide it into place.

    Align the front cover mounting slot and snap it into place
  • Press down on the rear end of the Y-axis top cover to ensure the snaps are fully engaged.

    Press down firmly to secure the rear cover's fixing clip

Step 10: Connect the Z-motor Cable

  • Push the heatbed to the screen side, use an Allen wrench to pry open the cable fixing tape, and manually remove it from the Z-motor.

    Pry open and remove the Z-axis motor factory fixing tape
  • Connect the Z-motor cable.

    Correctly insert the Z-axis drive motor signal cable
  • Replace the cable, ensuring it does not obstruct the installation area.

    Cable routing ensures no interference with mechanical structure
  • Take out the Z-motor cover from the accessory box and place the cover in the correct orientation.

    Snap on the original Z-axis motor external dustproof functional cover

Step 11: Connect the Integrated Cable Harness

  • Straighten the integrated cable harness, ensuring the cable is not twisted.

    Straighten the integrated ribbon cable
  • Ensure the connector is in the correct orientation with the letter A facing up, then insert the integrated cable harness into the back of the X-motor box.

    Confirm that the letter A is facing up and insert into the X motor connector

Step 13: Install the Purge Wiper Assembly

  • Manually move the toolhead to the middle of the linear rail.

    Move the print head module to the center of the beam

⚠️ Important Assembly Order:

Before installing the purge wiper assembly, make sure to manually move the toolhead to the center of the beam. Otherwise, the purge wiper assembly structure may jam the toolhead, causing hardware collisions, abnormal noises, or system errors during startup.

  • Take out the purge wiper assembly from the accessories and open the back cover.

    Open the dust cover on the back of the purge cutter module
  • Hold the cable at the end of the X-axis with your hand to ensure the slide slot is not obstructed, then slide the purge wiper assembly into the slot.

    Align the entire purge wiper assembly with the slot and snap it in
  • Take out 1 purge wiper assembly screw from the accessory box, and use an H2.0 wrench to tighten the screw to secure the purge wiper assembly.

  • Insert the connecting cable into the cable port.

    Insert the purge unit control communication cable

Do not pull the extremely thin internal connecting cable on the purge wiper assembly with excessive force, as this may cause breakage. When connecting the wires, you can slightly pull out a portion of the cable mesh at the end of the X-axis in the correct direction before connecting.

  • Organize the cables, tuck the connecting cable into the cable channel, and place the cable connector to the left.

    Arrange the cables neatly into the internal reserved cable management channel
  • Ensure the cables are placed as shown, then install the purge wiper assembly back cover.

    Confirm no cables are pinched before reinstalling and snapping the outer shell back cover

Step 14: Unfold the Touchscreen

  • Unfold the touchscreen.

    Flip and stand up the front IPS control touchscreen of the machine

Step 15: Install the Build Plate

  • Hold the build plate with both hands, align the edges with the heatbed, and gently lower it.
