Some of the parts used 2 Nema 17 Stepper motors - http://amzn.to/2vmdNtv 2 - GT2 20 teeth pulley - http://amzn.to/2wjVYZ5 5m ( you'll use less ) GT2 belts - http://amzn.to/2vmVioq 8 - M5 Idler - http://amzn.to/2vmwZHt Inspiration The first thing I thought when I saw the AxiDraw was "I want that" but then after a few seconds I said "I'm building that". I finished my design a couple of weeks after it was announced. Even though I have built my own CoreXY, I couldn't get into my head the belt path. After some research and help from the community, I got to the HBOT design. From there, it was just figuring out how to build it with whatever I had left from other projects. I was stuck for a couple of days figuring out how to build it, since I didn't want to use 2 plates to carry the linear bearing. Move this here, move that there until I hit the sweet spot. Objective Build a machine to be used with a laser diode to test LaserWeb, a very complete open source solution for lasers (cncpro.co). Simple to print, easy to assemble and mostly inexpensive. Needed to be small and able to carry it around. Sorry about the rust, but where I live even rust gets rusty. https://youtu.be/zJTmoou9EX8 Update: I'm using LaserWeb4 with GRBL 1.1, you can find the firmware here https://github.com/cojarbi/grbl-servo-CoreXY Print Settings Printer Custom CoreXY Rafts No Supports No Resolution 300 Micron Infill 30% Notes No support needed. I use a brim in every print I do. BOM - Bill of Materials Below you'll find a list for all the parts needed for this project. I'm a regular Amazon Prime customer, so I will link to them and as you'll see it's just easy to source. Electronics 2 - Nema 17 stepper motors 1 - Controller board Smoothie firmware based board > 32-bit boards highly recommended AZSMZ (The one I use) Azteeg X5 Smoothieboard GRBL firmware based board Hardware 1 Kit - GT2 timing belt with pulleys 1 Kit - Ball bushing linear motion (only 4 needed). 4 - 8mm Linear shaft. This will determine the size of the machine. Make sure the belt length is enough > 330mm long. 495mm Long. 6 - 625 Bearing. 4 - M5 x 25mm. 4 - M5 Nut. 4 - M3 x 20mm. 4 - M3 x 25mm. 4 - M3 x 10mm. 12 - M3 Nut. 4 - Washers. 4 - Shim. 10 - Zip ties small. 1 - Lead screw or similar + Nut and washers Laser Module L-Cheapo Laser Diode Configuration If you have an AZSMZ board or smoothie (changes would need to be made), you can use the config.txt provided. If you need help with GRBL, drop a request in the comment section and I'll post my settings
