Feature: 1. Pre-assembled for Plug\u0026Play: The machine is 100% installed in the package, equipped with an adapter cable, and only needs to be connected to the Y-axis wiring of the laser engraving machine to engrave Cylindrical objects, such as pens, water bottle, etc. 2. Large Engraving Space \u0026 4 Raising Feet: SCULPFUN roller base design is lower and stable, and equipped with 4 sturdy metal raising feet, so that it has a larger engraving diameter of 6-150mm, which can meet more engravings need. Metal feet are more solid than plastic feet, and the machine is more stable when engraving. 3. Sliding Space Adjustment: Adjusts the size of the space between the 2 rubber rollers by sliding, and fixes the roller by hand screw, which is simpler and faster than the traditional multi-stage fixing hole adjustment. 4. 100% Scale High-precision Engraving: Our roller adopts high friction 70A rubber shaft to prevent slipping, and the linear speed of the rotating surface has been precisely calculated. Directly plug in the engraving machine cable to engrave the image in 100% scale. Does not enlarge or reduce the image. 5. Wide Compatibility: The roller is suitable for multiple engraving software such as lightburn or laserGRBL, and it can be used directly, no need to set parameters in software. In addition, it can be applied to 95% of the engraving machines on the market such as SCULPFUN, NEJE, Ortur, ATOMSTACK, etc. Specification: Features: Pre-assembled for Plug&Play:The machine is 100% installed in the package, equipped with an adapter cable, and only needs to be connected to the Y-axis wiring of the laser engraving machine to engrave Cylindrical objects, such as pens, water bottle, etc. Large Engraving Space & 4 Raising Feet:SCULPFUN roller base design is lower and stable, and equipped with 4 sturdy metal raising feet, so that it has a larger engraving diameter of 6-150mm, which can meet more engravings need.
