LienCNC V2 (CNC Router)

<p>I would like to introduce the LienCNC V2, which is a CNC router I designed as an upgrade to my previous CNC Router. I completed this new router design and build during December of 2020. The previous router I used was the R7 CNC which was a project I helped develop with my friend Brandon who owned SMW3D/HobbyFab. The R7 CNC was a great machine and cut all the aluminum parts required to build my new machine. The majority of the work I do on my router is cutting aluminum, so I wanted something with higher stiffness, higher mass for dampening vibrations, and all around overbuilt just how I like it.&nbsp;</p><p>The performance of this new machine checks all the boxes I had hoped for during my time in Solidworks designing the upgrade. The major specifications for this CNC design are as follows:</p><p><i><strong>Construction:</strong></i> 8020 Aluminum Profiles and ½” ATP-5 Cast tooling plates<br><i><strong>Motion:</strong></i> RM1605 (5mm pitch) Ball Screws, HGR20 Linear Rails, Nema24 3Nm Closed Loop Steppers<br><i><strong>Spindle:</strong></i> 2.2KW ER20 220V 24000RPM Spindle<br><i><strong>Controls:</strong></i> Minisforum UM300 MiniPC into CNCDrive AXBB-E Controller w/ UCSB Breakout<br><i><strong>Software:</strong></i> CNCDrive UCCNC 1.2113<br><i><strong>Power Supplies:</strong></i> 48V/20A Main PSU, 24V/2.5A PSU, 5V10A PSU, 48V-to-12V 5A Buck Converter<br><i><strong>Machine Travel:</strong></i> X=738mm / Y=724.5mm / Z=129mm<br><i><strong>Max Speed:</strong></i> X=8,000mm/min / Y=10,000mm/min / Z = 8,000mm/min</p><p>There are not a ton of 3D printed parts on this CNC, the majority of them are cut out of ½" aluminum. But I wanted to make the design available here since I think there is a lot of crossover in the maker community between 3DP and CNC machining. &nbsp;</p><p>Due to the file type and size limitations on Prusa Printers I cannot upload all the files I have made available. For additional details and the most up to date information Please see my Github repository at:</p><p><a href="https://github.com/eclsnowman/LienCNC-V2">https://github.com/eclsnowman/LienCNC-V2</a></p><p>In the files I have on my Github are all my native Solidworks 2018 design files, as well as those files converted into many other 3D formats including; Fusion360, Step, Iges, Etc.&nbsp;</p><p>It is also out on Onshape: <a href="https://cad.onshape.com/documents/7925f5cfb31619e7f18499a5/w/4ba7961a002dc98003c3f25c/e/a22e33a006f69546cb8de1a5.">https://cad.onshape.com/documents/7925f5cfb31619e7f18499a5/w/4ba7961a002dc98003c3f25c/e/a22e33a006f69546cb8de1a5.</a></p><p>In addition to 3D models, I have included PDF, DXF, and DWG prints for all the major fabricated components and assemblies. The manuals for all the components that I referenced for configuring my build are also included. Lastly I have included my UCCNC configuration *.pro” file which has been tuned and setup for this machine.</p><p>The only item I have not included is a wiring diagram. Unfortunately the time it would take to make a wiring diagram to the caliber I could feel proud of is just not something I have time for right now. Building a CNC requires a fairly ample back catalog of knowledge to take on. If the wiring of a project like using the electrical manuals is not something you feel comfortable with, then seeking advice from an expert on your project would be advised. That being said I have included pictures and 3D models of my electrical cabinet design that you could use as reference on your own project.</p><p>I hope the files, resources, pictures, and designs I have provided here can help you if you decide to take on this project. And if you don’t build this design, I hope these resources can act as a jumping off point for your own project.</p><p>If you find any errors that I should correct please feel free to submit a pull request with the changes, or submit an issue and I will do my best to correct the problem as time allows.</p><p>Happy Making, – Eric Lien</p>
