The Kobra 3 Combo printer has been calibrated before leaving the factory. After completing the operation according to the novice guide function of the machine, it can print directly. If the machine is abnormal due to transportation reasons, we may need to manually calibrate it to ensure that the printer is working properly.
¶ 1. Tools：
H10 Wrench*1
S2.5 Allen key*1
S3.0 Allen key*1
Feed tray*1
¶ 2. X-axis component calibration
¶ Step 1: Check the print head module
Check if the print head module is loose, as shown in the figure.
1. If the print head module is loose, please refer to the following steps to adjust it.
Use H10 Wrench to adjust the eccentric column of the print head module.
2. Make sure all bearing wheels are in contact on both sides of the double-axis core without any shaking.
3. Check that the X-axis bearing wheel can move smoothly on the double-axis core.
¶ Step 2: Check the X-axis component level
If the X-axis assembly is tilted, please follow the steps below to calibrate it.
1. Keep the X-axis synchronous belt in a relaxed state before calibration.
2. Use the S2.5 Allen key to loosen the fixing screw.
3. Pull the synchronous belt to move the X-axis assembly to the material tray, so that the X-axis assembly presses the material tray.
4. Use your hands to apply downward pressure to the X-axis assembly.
5. While applying downward pressure, use the S2.5 Allen key to tighten the fixing screw.
6. The calibration is completed and the X-axis timing belt is in a tightened state.
¶ 3.Y-axis component calibration
If the heating bed is shaking, as shown in the figure.
