One 2M2 Magic Tank user feedback he has HON66 [No.25] to cut, but he has the confusion that : aafter calibrating the left side ,the right side is not equal (Left side=2.9mm, Right side =3.0mm).
2M2 chief engineer replied:
Please ignore the number of calibration, the position of cutter and tracer depend upon the number after calibration, so the number has a little tolerance that is normal. The most important is to put the blade 25# into the right position. that is okay.
