Since the Heidenhain X axis ruler of the SNK RB2 18M CNC milling machine was faulty, a new ruler was installed. Since the faulty ruler, the old series (LB302), was no longer produced, a new generation ruler (LB382) was installed instead.
However, since there was a micron measurement difference between the two rulers, it was said that the relevant parameter had to be changed by Fanuc.
Old ruler 100 microns New ruler 40 microns
Can you help me with the relevant parameter?
