Description

No cylinder was found during laser measurement.

Remedy

First, adjust the setting of exposure so that an appropriate laser image can be obtained. Next, make sure that the laser measurement area was taught properly. If the pattern match model origin is changed after the laser measurement area has been taught, it is likely that the laser measurement area may move to an unintended position during execution. If you changed the model origin, re-set the laser measurement area. If these methods cannot solve the problem, adjust the detection parameter for the string of laser spots.
