Xa usebenzisa umatshini wokusika i-laser, uvavanyo lokugcinwa rhoqo kunye nokutshekisha rhoqo kufuneka ukuze iingxaki zifumaneke kwaye zisonjululwe ngokukhawuleza ukuphepha amathuba okungasebenzi komatshini ngexesha lokusebenza, kunye nokuqinisekisa ukuba izixhobo zisebenza ngokuzinzileyo. Ke yintoni umsebenzi oyimfuneko phambi kokuba umatshini wokusika welaser uvulelwe? Kukho iingongoma ezizi-4 eziziintloko: (1)Jonga yonke ibhedi yokulala; (2)Jonga ukucoceka kwelensi; (3)I-coaxial debugging yomatshini wokusika we-laser; (4)Jonga ubume bomatshini wokusika i-laser.
