Take the Instructables Laser Cutting Class. In order to mount the limit switches at the required axis locations, a set of 3D printed mounting plates were designed, along with another set of plates to trigger the switches. Wiring Gauge The RepRap Wiki page recommends using 22AWG or 20AWG but in my experience these gauge sizes do NOT fit the most common connector types used in 3D Printer Controller Boards. Mounting holes to mount to side rail. Introduction 1. China finally came online as a cheap manufacturing center for low cost consumer 3D printers. According to popular opinion, "real" lasers like the JTech 4.2W (~$475), the JTech 7W (~$675), Endurance lasers, etc have considerably more power than these cheap "5.5W" lasers. Did you make this project? Item Information. This may sound stupid, but believe me, when focusing the laser, it's tempting to reach in there and move the board around instead of jogging the controls w/ Lightburn. Though I think it's overkill, it's probably the proper and responsible way of doing things. I designed & 3D printed a part that holds the laser UP high enough to avoid interfering with 3D printing mode, and OUT far enough to avoid interfering with homing. It's pretty primitive, but gives a basic idea of simply capturing fumes and sending them outside. I ordered 3x of the 12x12 Panels from JTech to surround the laser area. I'll try to keep them short. - Anne Dilliard ...
