Problem Description
Under normal conditions, the two red dots on the LP5 should coincide when the machine reaches the optimal focal distance. When the red dots overlap, engraving can proceed normally.
If the two red dots do not coincide after reaching the optimal focal distance, as shown in the image below, follow the troubleshooting steps in this guide to recalibrate the red dots.
Troubleshooting Steps
1. Connect your LP5 to the LaserPecker Design Space App.
2. Enter the creation interface, then tap the Settings icon in the upper-right corner to open the Mode Settings page.
3. In Mode Settings, enable Red Dots Always On.
4. Tap Start Calibration to begin the dual red dots calibration process.
5. Place a stainless steel sheet or another metal sheet at the center of the Base Plate. At this point, ensure that the two red dots are roughly centered on the metal sheet.
6. Adjust the height of the Electric Stand so that the two red dots overlap as closely as possible, then proceed to the next step.
7. Tap Laser Engraving. The machine will begin engraving a square on the metal sheet.
8. Slowly adjust the height of the Electric Stand upward or downward until the engraving sparks reach their highest intensity. Stop adjusting at this point, wait for the engraving process to complete, and then proceed to the next step.
9. Using an H1.5 hex key, adjust the two set screws located at the bottom of the Laser Unit until the two red dots fully overlap. Once the red dots overlap, the calibration is complete.
Additional Notes
1. Movement Direction of the Calibration Screws
The two calibration screws both control the same red dot (the brighter red dot).
2. Calibration Screw Functions
Outer set screw (vertical calibration)
- Clockwise rotation: the red dot moves upward
- Counterclockwise rotation: the red dot moves downward
Inner set screw (horizontal calibration)
- Clockwise rotation: the red dot moves to the left
- Counterclockwise rotation: the red dot moves to the right
3. Red Dot Does Not Move During Calibration
Due to the limited adjustment range of the red dots, if the red dot does not move during calibration, it is usually caused by one of the following situations:
(1) The set screw is fully tightened
The screw has reached the limit of its adjustment range and cannot be tightened further.
(2) The set screw is excessively loose
The screw has loosened beyond its normal adjustment position and may be close to falling out.
Solution:
Slowly rotate the set screw in the opposite direction until the red dot begins to move, then continue calibration as instructed.
