Laser Beam Alignment Check

Each target has two scorches made at the left and right ends of the gantry X axis, positioned along the Y axis as noted:

The target has maybe a millimeter of positioning error in the mirror entry aperture, so the beam remains pretty much where it should be.

The beam is hotter toward the rear, as expected, and the front target needed two or three pulses to get a good scorch in the right front corner.
