Lidar scan data for calibrate filament


Why is it not possible to view the data of the lidar for the filament by the calibration?
I wish it give a calibration function where the filament calibrate with the lidar and store the data.
Now you can use the lidar only before the print start.
The next problem is that the printline for the calibration is too fast.
I only print the first layer with 30-50mm/s but the lidar line is much faster.
About that the line is not hold on the bed.
