Is there a way to set one start location for the laser, to be used for several subsequent burnings? My project: I want to engrave the sides of a cube. My idea was to clamp alignment pieces to the laser grid bed to make sure the cube is in the same position for every engraving. Then use the red dot pointer to orient the file onto the cube side, engrave the first side, turn the cube, engrave the second side, ... The design is intended to flow around the sides of the cube. Thus precise alignment between the burnings is important. However, I find this difficult. One reason being the diameter of the red dot.
