Laser Engraver Mk 2

thingiverse

I've made some changes to this design, so I'm calling it Mk 2 instead of sticking with the original. I've included the 123d files, which you can easily modify or customize to suit your needs. I've put in a lot of effort on this project and I hope others will find it useful. All parts were printed using an Anycubic i3 Printer with a bed size of 210 by 210 mm. The end parts require some tweaking to get them into the slicer, but they fit perfectly diagonally. The square holes are designed for Microswitches, which I used from this eBay link: https://www.ebay.co.uk/itm/331890551081 UPDATE: I've also added a laser module, which can be purchased from Banggood at this link: https://www.banggood.com/450nm-3500mW-3_5W-Blue-Laser-Module-With-TTL-Modulation-for-DIY-Laser-Cutter-Engraver-p-1103261.html?rmmds=myorder&cur_warehouse=CN. You can find cheaper alternatives by searching online, but I paid £54 for mine from the same supplier. The Nima 17 stepper motor is a 17HS3404 model. I'm using four rods, two at 260mm and two at 388mm in length. The control system is based on GRBL and Inkscape, with Universal Gcode sender as the interface. This machine may not be the most advanced, but it's affordable and effective. To upgrade the bed, I plan to use a piece of plywood or aluminum, as shown in this YouTube video: https://www.youtube.com/watch?v=KitOc0eEnhw
