The technical characteristics of Orbiter v3.5 remain largely the same as those of Orbiter v3.0.\u003c\/p\u003e\n\u003cp\u003eThe main change in Orbiter v3.5 is the redesigned front heatsink. The new fin shape reduces air turbulence and helps eliminate the annoying ‘mosquito’ fan noise (~-10dB). \u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1477\/4314\/files\/orbiter-heatsink-comparison.jpg?v=1782111624\" width=\"2446\" height=\"1018\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003eThe front heatsink is designed to be compatible with both the LDO hotend design and the E3D Revo ecosystem.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1477\/4314\/files\/orbiter-hotend.jpg?v=1782111772\" width=\"2446\" height=\"1018\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003eNote: The E3D Revo hotend is 4 mm longer than the LDO hotend!\u003c\/p\u003e\n\u003cp\u003eThe heatsink and hub housing have been widened by 0.5 mm. This ensures that the left-side extruder mounting surface sits further outward than the stepper motor body, improving mounting alignment. As a result, the Orbiter v3.5 is 0.5 mm wider than the previous v3.0.\u003c\/p\u003e\n\u003cp\u003eThe front heatsink and filament guide are now combined into a single part, improving tolerance control of the filament path and its distance to the filament sensor. This also reduces the number of parts that need to be aligned, making the design less sensitive to manufacturing tolerances. \u003c\/p\u003e\n\u003cp\u003eThe input ring geometry has also been redesigned to accept a small PTFE coupler, ensuring the PTFE tube is mechanically retained rather than relying only on friction.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1477\/4314\/files\/orbiter-two-part-design.jpg?v=1782111961\" width=\"2446\" height=\"1018\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003eAs shown above, the filament sensor has been redesigned using the same sensor switch as the Orbiter v2.0 smart filament sensor. This results in more reliable filament detection, reduced friction in the upper section of the extruder, and more reliable runout detection without false events.\u003c\/p\u003e\n\u003cp\u003eThe new sensor board features two RGB LEDs instead of one, so the Klipper RGB LED configuration must be updated to define two LEDs in the chain_count.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/www.orbiterprojects.com\/wp-content\/uploads\/2026\/02\/image-5.png\" width=\"347\" height=\"272\" alt=\"\" style=\"display: block; margin-left: auto; margin-right: auto;\"\u003e\u003c\/p\u003e\n\u003ch3\u003eDrive Gear Tension Lever\u003c\/h3\u003e\n\u003cp\u003eThe retaining screw for the secondary drive gear tension lever has been changed from a standard M3 screw to a custom M3 shoulder bolt. This allows the tension lever to pivot on a smooth surface rather than on the M3 threads, as was the case with Orbiter v3.0.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/www.orbiterprojects.com\/wp-content\/uploads\/2026\/02\/image-6.png\" width=\"1766\" height=\"1593\" alt=\"\"\u003e\u003c\/p\u003e\n\u003ch3\u003eKnurled Spider-shaft design\u003c\/h3\u003e\n\u003cp\u003eAnother change is a new knurled spider-shaft design. Compared to the previous precision shaft (octagon-shaped), the knurled version is easier to manufacture and allows the drive gear to be press-fitted with better alignment. This improved centering leads to more stable extrusion and smoother print quality, reducing visible diagonal artifacts.\u003c\/p\u003e\n\u003ch3\u003eBrowse more\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrowse all \u003ca href=\"https:\/\/www.phaserfpv.com.au\/collections\/ldo-motors-australia\"\u003eLDO\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003eBrowse all \u003ca href=\"https:\/\/www.phaserfpv.com.au\/collections\/3d-printer-extruders\"\u003eExtruders\u003c\/a\u003e\n\u003c\/li\u003e\n\u003cli\u003eBrowse all \u003ca href=\"https:\/\/www.phaserfpv.com.au\/collections\/voron-australia\"\u003eVoron Parts and Accessories\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LDO","offers":[{"title":"Default Title","offer_id":47260567699627,"sku":"35044","price":169.95,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1477\/4314\/files\/ldo-orbiter-v3-5.jpg?v=1782112135","url":"https:\/\/phaserfpv.com.au\/products\/ldo-smart-orbiter-v35","provider":"Phaser FPV","version":"1.0","type":"link"}
