<h3>Update: FuseBox2R v1.1 files are available on Github. Reworked gantry is more rigid and has an improved belt path. A partially complete build guide has also been added.</h3> <h3>FuseBox2/FuseBox2R</h3> <hr/> <h3>Github repo (Check here for latest part files, BOM, instructions, etc.): <a href="https://github.com/alexyu132/fusebox2">https://github.com/alexyu132/fusebox2</a></h3> <h5>Update 7/27/18: STLs and files will now be on Github only.</h5> <h5>Update 3/20/18: Modified extruder to be compatible with flexible filaments. Tested with TPU @25mm/s.</h5> <p>An affordable and robust CoreXY printer loosely based on the original FuseBox. Materials cost ranges from $300-400 largely depending on what hotend and electronics you choose to use.</p> <h4>FuseBox2R</h4> <p>Improves on the original FuseBox2 by replacing the gantry rods with a single MGN12 rail and MGN12C carriage. Improvements include 30% lower moving weight, quieter movement, easier access to carriage components and a modular cooling duct. With a clone rail, upgrading costs ~$15-20 and building from scratch adds about $5-10 to the total cost.</p> <h3>Videos</h3> <p>FuseBox2R v1.1 @ 250mm/s: <a href="https://youtu.be/t1YAJrRtNjg">https://youtu.be/t1YAJrRtNjg</a></p> <p>170mm/s printing: <a href="https://youtu.be/dm6vGjRgSQ8">https://youtu.be/dm6vGjRgSQ8</a></p> <p>Marlin 2 speed test: <a href="https://www.youtube.com/watch?v=aUQ9sjp_YzY">https://www.youtube.com/watch?v=aUQ9sjp_YzY</a></p> <h3>Specifications and Features</h3> <ul> <li>Rigid 2020(top and sides)/2040(bottom) aluminum extrusion frame</li> <li>Non-crossing CoreXY belt path</li> <li>210x200x210mm build area</li> <li>390x340x412mm size</li> <li>MK2 or MK3 PCB heatbed with 3 point leveling</li> <li>Strong part cooling blower (4020s)</li> <li>E3D V6 or Lite6 + 40mm cooling fan and Bowden extruder</li> <li>24v + 32 bit electronics recommended</li> </ul> <h3>Improvements over original FuseBox</h3> <ul> <li>Slightly more compact</li> <li>Slightly larger build area</li> <li>2020 frame for much greater rigidity</li> <li>Belt tensioning improvements - much easier to tension and screw-clamped to prevent slipping out</li> <li>Screw-clamped bearing and rod mounts - no more structural zip ties</li> <li>Proper belt idlers - eliminates belt rubbing</li> <li>(Optional) Extrusions joined via tapped ends + screws instead of corner brackets</li> <li>Lowered part count - y rods integrated into motor and idler mounts</li> <li>Vertical gantry for easier hotend installation/removal and better cooling</li> <li>Better endstop mounting and easier adjustability</li> <li>Robust electronics mounting with integrated display and IEC switch/fuseholder mounts - PSU flipped upside down for a cleaner look and so cooling fan doesn't interfere with heatbed</li> </ul> Category: 3D Printers
