The laser is to the left, X is positive, the nose is deviated from
the right of the plan line and needs to be repaired to the left
The correction position is basically in the same direction as the laser, that is, when the
laser is in the upper right, the correction point is also in the upper right.
After the correction, you must pay close attention to the laser movement trend and
correct it back at the right time. If you are going back to repair the laser when it is in the
middle, the laser will move in the opposite direction and produce a snake phenomenon.
Assume that the head is left (x=-20). You fix it to the right. After pushing 1M, the
head is left (x=-23), indicating that your correction is not enough. You need to fix it a little
more to the right; if you push 1 meter After that, it is still (x=-20), indicating that the nose
will not continue to shift to the left. Please continue to observe after halving the
correction. If the offset starts to decrease, the head will return to the design line. At this
time, you The correction can be repaired to 0 to avoid returning too fast to produce a
snake moving.
The above correction method is for reference only, and the specific implementation
method must consider the situation in the field!
