I was looking for something which could print tall objects, occupy small space on my desk and of course be a cheap one \ud83d\ude42 Delta printer was the only one that needed not much horizontal space. Vertical dimension of delta is another story, but I didn&#8217;t care about it. So, I bought Anycubic Kossel, but it turned out that seller didn&#8217;t control his own stock and I&#8217;ve got nothing except my money back. Then I bought this EZT-3D T1 &#8211; cheapest printer with intention to upgrade it later. Long story short: easiest way to upgrade this printer is to build or buy new one.<\/p>\n<p>During this year I started collecting parts for new printer: bigger and better delta. But recently 2 things happened: I got rid of one monitor from my desk and get more room for something, the second thing was that I found that there are CoreXY machines. Analyzing theirs mechanics I found that it could be possible to build something with much larger build volume than my current printer and still fit on my new spare space on the desk. I have 35cm of width available, maybe I could add few more, but not much more. I started to check already available products and projects, but I found nothing that could fit in less than 40cm of width and have decent build volume size. I had no other option than to start designing it myself. That way <strong>Very Narrow CoreXY<\/strong> 3D printer aka <strong>vn-corexy<\/strong> was born:-)<\/p>\n<h1>The printer<\/h1>\n<p>My basic assumptions for designing this machine was:<\/p>\n<ul>\n<li>reduce width to minimum, even at some cost in other dimensions (because of my space constraints), but not at any cost \ud83d\ude42<\/li>\n<li>make it more compact compared to other available designs, but a little less universal, for example by limiting printing head size<\/li>\n<li>build volume about 300x300x300mm (because I need more than my current printer)<\/li>\n<li>CoreXY mechanics (because I think it&#8217;s most compact and could be as fast as delta)<\/li>\n<li>use linear rails on X and Y axis (because I already got them for my next delta)<\/li>\n<li>use one motor for Z axis (because I already have control board that can&#8217;t handle 3)<\/li>\n<li>OpenSCAD used for designing (because it&#8217;s free, available on all platforms and I was already using it for many smaller projects before)<\/li>\n<li>it should be open source, so I created repository on Github:\u00a0<a href=\"https:\/\/github.com\/majekw\/vn-corexy\">https:\/\/github.com\/majekw\/vn-corexy<\/a> , and because OpenSCAD files are just &#8216;code&#8217;, version control is really helpful in tracking changes<\/li>\n<li>use as many parts as possible from what I already bought for new delta (linear rails, motors, BMG extruder, belts, pulleys, electronics etc.)<\/li>\n<li>custom parts should be easy printable on any crappy 3d printer, without supports if possible<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p>First rendering of vn-corexy:<\/p>\n<h1><a href=\"https:\/\/majek.sh\/wp-content\/uploads\/2021\/01\/vn-corexy-20201230.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-2007\" src=\"https:\/\/majek.sh\/wp-content\/uploads\/2021\/01\/vn-corexy-20201230-445x480.png\" alt=\"\" width=\"445\" height=\"480\" srcset=\"https:\/\/majek.sh\/wp-content\/uploads\/2021\/01\/vn-corexy-20201230-445x480.png 445w, https:\/\/majek.sh\/wp-content\/uploads\/2021\/01\/vn-corexy-20201230-139x150.png 139w, https:\/\/majek.sh\/wp-content\/uploads\/2021\/01\/vn-corexy-20201230.png 748w\" sizes=\"(max-width: 445px) 100vw, 445px\" \/><\/a><\/h1>\n<p>At this stage frame dimensions was set and axis drive was sketched.
