¶ What it is
HMS_0C00_0100_0002_0007: Micro Lidar laser parameter drifted
Since we have two lasers on the Micro Lidar, measuring the depth of the same point using the two lasers should give the same result. If the results are different than a given threshold, this message will appear, indicating that the parameter of the two lasers are no longer correct.
¶ Why does this happen
The laser parameter encodes the spatial distance and angle (i.e. transformation) between the laser and camera. They are supposed to rigidly connected. However, the connection is not strong enough to resist the vibration of toolhead. During long-time usage, the transformation may change, and the laser parameter is no longer accurate. We call this phenomenon “drifting”.
¶ Operation guide
Solving the issue is easy, just run the calibration.
¶ step1
Enter the screen calibration page, click to start calibration, wait for the calibration to end.
¶ step2
Restart printing and check if the error message disappears
¶ step3
If the message is still there, check if the calibration marker is clean and uncovered.
¶ How to verify completion/success
The message should disappear if problem solved.
