When marking with CerMark LMM-6000 or 6038, we use a useful technique here in the lab to help us line up our marks. To test the position of the mark, the LMM can first be discolored using very low power without bonding it to the metal. For example, if using a 35 watt laser, you can run the mark at about 10% power and 100% speed to see its position. The LMM will be discolored on the surface, but it won't be bonded to the metal. If the positioning is correct, you can then mark normally at 100% power and your usual marking speed. This can be very helpful in lining up an image on an odd shaped part.
Note: Be careful not to use too much power when trying this, if you bond any LMM to the part it will be very difficult to remove it without ruining the piece. It is better to start off too low in power than too high.
