I always admired ultimaker for the print quality they could produce, but at the same time thought their machines were hugely overpriced, and their close sourced\/hard to mod mentality also don&#8217;t help my view on them, after all I like to tinker and mod stuff. I personally would never buy a ultimaker simply because I believe the same amount of money can be spend better elsewhere. The crossed gantry mechanism consists of 4 stationary smooth rods and two moving smooth rods. The two moving rods are then connected via two bearing\/bushings on the print head(.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-b1dc455 elementor-invisible elementor-widget elementor-widget-image\" data-id=\"b1dc455\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;_animation&quot;:&quot;fadeIn&quot;}\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t<figure class=\"wp-caption\">\n\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"1000\" height=\"609\" src=\"http:\/\/d3h.dk\/wp-content\/uploads\/2021\/02\/Ultimaker-Motion-System.png\" class=\"attachment-full size-full wp-image-896\" alt=\"\" srcset=\"http:\/\/d3h.dk\/wp-content\/uploads\/2021\/02\/Ultimaker-Motion-System.png 1000w, http:\/\/d3h.dk\/wp-content\/uploads\/2021\/02\/Ultimaker-Motion-System-300x183.png 300w, http:\/\/d3h.dk\/wp-content\/uploads\/2021\/02\/Ultimaker-Motion-System-768x468.png 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/>\t\t\t\t\t\t\t\t\t\t\t<figcaption class=\"widget-image-caption wp-caption-text\">XY motion system of a Ultimaker Gen 3.

You need six rails instead of 3 and you need 4 motors instead of 2. You need 4 stepper drivers instead of 2 (do not do this with 2 motors on one driver as you will need to home then individually to avoid racking).<\/span><\/span><\/li><\/ul><p>\u00a0<\/p><ul><li><span class=\"tojvnm2t a6sixzi8 abs2jz4q a8s20v7p t1p8iaqh k5wvi7nf q3lfd5jv pk4s997a bipmatt0 cebpdrjk qowsmv63 owwhemhu dp1hu0rb dhp61c6y iyyx5f41\"><span class=\"tojvnm2t a6sixzi8 abs2jz4q a8s20v7p t1p8iaqh k5wvi7nf q3lfd5jv pk4s997a bipmatt0 cebpdrjk qowsmv63 owwhemhu dp1hu0rb dhp61c6y iyyx5f41\">The machine has a bigger footprint compared to printable area due to the extra gantry. <br \/><\/span><\/span><\/li><\/ul><p>\u00a0<\/p><ul><li>The tool changing concept gets more complicated as one way or another the idle tools must be lifted when printing and lowered when changing tools. This is required to avoid collisions with the second gantry.
