MachCube 2.0 - 3D Printer

thingiverse

Hi Everyone, this is my latest open source 3D printer design. Before I decided to design this 3D printer, I was looking for an open source 3D printer design that I could easily take over and build myself. After checking out many available open source designs, I realized none of them met my requirements, so I decided to create my own version of a Core XY printer that incorporates the best ideas I've seen during my research. The key features of this design are: * Based on Duet WIFI + Panel Due control boards; * XY Core design - extremely accurate and fast printing; * All axis slides on MGN rails; * Dual color hot end; * Maximum XY speed 300mm/s; * Open front structure; * Very compact design, with the smallest overall size compared to print area; * Low noise - passive cooling for motors and soundproofed walls. Here's a video of the printer in action printing up to 250mm/s with its new remote direct extruder setup: Print testing between 50-250 mm/s: https://youtu.be/4bbcH8Qa4JU Results look pretty good. I also tried printing at 300mm/s, where slight under-extrusion was visible in areas where the printer reached that speed. Printing with 150mm/sec: https://youtu.be/83xA3AYlX5c Extruder stepper in action @150mm/s printing speed: https://youtu.be/7qfuxtMpvR4 The build area is completely customizable. The maximum build size for this frame should not exceed 300x300x300mm - see attached frame calculator. My printer is built with a 275x220mm heated bed build plate and 250mm height. Overall printer size is 470x395x445mm. My main objectives for this design were to have the smallest possible printer size and reach standard printing speeds over 150mm/s without compromising print quality. To achieve this, I focused on making the X carriage as light as possible. You must consider that the energy (e) of moving mass (m) increases exponentially with speed (V). e = (m * V^2) / 2 For example, to go from 100mm/s to 200mm/s would require a moving mass four times lighter than what's currently used. Obviously, this is not possible. Therefore, to reach higher speeds without compromising print quality, we need four times more rigid frame and power from the XY motors. I've made the design fully open source and have used SketchUp for the design (although I regret it now). Now, I'm working on moving the design into Fusion 360, which is not a simple task! To build this printer, you'll require patience (it took me over one week to complete), passion for 3D printing, and technical abilities in both electrical and mechanical areas. I guarantee that the result will be worth all the effort! To-do List: * Upgrade to geared dual drive BondTech extruder (the current one is not geared, and under-extrusion becomes a problem at high speeds); * Integrate an additional 5V supply + USB TYPE A connector for supplying external IP webcam; * Create nice pictures/video to show the awesome print quality of this printer; * Finish documentation and instructions; * Design a new fan-duct for high-speed PLA printing - this "monster cooler" is not bad, but I've seen designs with similar results using only one fan. Note: I'll do my best to update the project regularly! P.S. Marked as a remix of "BLV mgn Cube" with permission/request from BenLevi. Thanks Ben for sharing your great work with us!
