Delta Kossel Effector + Laser Mount

thingiverse

Here’s a special effector I designed to mount a laser engraving module on my delta 3D printer that can be mounted and disassembled without disturbing the settings and mechanical parts of the printer. It's placed in a simple slide and locked by a small part, allowing you to quickly and easily switch from printing to engraving. When the laser isn't mounted, it can be placed on its support on the side of the printer. In addition, the two radial fans provide optimum cooling for 3D printing. The laser is positioned at -42.5mm on the Y axis with respect to the nozzle, and I glued a wooden disc on a borosilicate disc with the same difference. The engraving bed is simply moved while the available area remains the same. List of parts to be printed (without supports): Effector Mounting bracket (print with 10% filling, supports already included) Locking effector part Diffusers (to be glued into the fans) Laser slide Locking slide part Laser support (if needed) List of screws required: 4x M3*8mm 1x M3*10mm 6x M3*12mm 3x M3*16mm 2x M3*20mm (2x M4*8mm and nuts, if laser support is needed) List of material: Laser Module (for example: https://fr.aliexpress.com/item/Focusable-Diode-Laser-1000mW-450nm-Blue-Laser-Module-with-TTL-Driver-for-laser-engraving-machine-cnc/32642400998.html?spm=2114.13010608.0.0.tTVbcP) 2x radial fans 50*50mm Axial fan 30*30mm Softwares: To engrave an image: Laser Etch B/W Image Engraving by J Tech Photonics (https://jtechphotonics.com/?product=laser-etch-bw-image-engraving-sw-license). This program decomposes a BMP image into lines and generates the gcode. The engraving is done line after line as an impression. To engrave outline and to cut: Inkscape (https://inkscape.org/en/) + Inkscape Laser Plug-In by J Tech Photonics (https://jtechphotonics.com/?page_id=2012). Delta printers doesn’t support G2 and G3 arcs commands, so for the moment, I have not found any other solution than to break arcs in linear segmentations. In Inkscape I use the function: Extensions > ModifyPaths > Flatten Beziers. Ask me if you are interested in the electrical connections and softwares configuration. I will add more info if needed. Have fun and think safety first by protecting your eyes! Print Settings Printer Brand: RepRap Printer: RepRap Kossel Rafts: No Supports: No Resolution: 0.2 Infill: 20% Notes: PLA 1.75mm
