This accessory ensures proper leveling of circular surfaces held by the rotary extension. For precise marking or engraving on metal or circular glass surfaces, the object must be perfectly aligned with the horizontal plane passing through the laser's focal point. Misalignment can result in incomplete or uneven engraving, leading to poor-quality results.
To adjust the height of the rotary motor, simply turn both knobs simultaneously until the desired leveling is achieved. This feature enables handling of objects with larger radii, providing greater versatility and precision.
Assemble the parts as illustrated in the figure. Fully thread both screws into the support crossbar, then carefully insert them into the base. Attach the caps, secure them with super glue, and fit the grip discs to facilitate screw adjustment.
Next, position the rear of the rotary extension on the support crossbar. Adjust the height by simultaneously turning the knobs to the left or right until the desired position is reached.
