Mecpow G3 Laser Rotary Roller, Laser Engraver Y-axis Rotary Roller Engraving Module for Cylindrical Objects, Compatible with Most Kinds of CNC Laser Cutter and Engraver Machine, 3D Printer Accessories

The item arrived intact and in good condition despite the box not being sealed in any way. There was no sealing tape on the box at all.

Works great for hydro flasks too! The rubber is super grippy so you don’t have to worry about it slipping. It also includes risers for the laser. Super easy to setup.

This item came fast. Exrtreamly easy to set up and use. Beautifully engravings.

Out of the box this rotary roller did not work with my Comgrow Z1 10W diode laser. One thing to note, most of these simple lasers have 2 motors on the Y-axis, so be sure to unplug the wire harnesses from each motor. Then just choose 1 to use with the included jumper harness. For me, I actually swapped 3 of the 4 pins on the white end of the jumper. This can be accomplished with a tiny flathead jewlers screwdriver and lifting the little white tab up while pulling out the terminal (see photo). My finished reworked harness is also included in a photo. After all that, it started to work just fine.One note if you're a Lightburn user, I used the rotary tool wizard found under the Laser Tools menu. My settings I ended up with were 218 mm per rotation and the roller diameter of 12.5 mm. Hope this helps!
