By replacing the standard multi-piece drive gear\n  and shaft assembly with a single machined unit where gear and shaft are manufactured as\n  one component, the IDGA eliminates the eccentricity that accumulates at the press-fit\n  or keyed interface of conventional drive gear assemblies — delivering more consistent\n  filament engagement per revolution and a measurable improvement in print surface quality.\n\u003c\/p\u003e\n\n\u003cp\u003e\n  ⚠️ \u003cstrong\u003eCompatible with Voron Clockwork 2 (CW2) only.\u003c\/strong\u003e This is not\n  compatible with BMG, LGX, or other extruder types — those use different IDGA variants.\u003cbr\u003e\n  ⚠️ \u003cstrong\u003eSecondary drive gear, secondary shaft, and secondary needle bearings\n  are NOT included.\u003c\/strong\u003e This set replaces the primary drive gear assembly only.\n  For a complete drive gear kit including IDGA, use the BMG Drive Gears IDGA Kit.\u003cbr\u003e\n  ⚠️ \u003cstrong\u003eAxial play is required.\u003c\/strong\u003e When installing, allow a small amount\n  of axial play in both directions — this lets the filament path self-correct.\n  Do not constrain the shaft completely.\u003cbr\u003e\n  ⚠️ \u003cstrong\u003eMotor-face bearing clearance: ~0.4mm.\u003c\/strong\u003e The bearing facing the\n  motor should have approximately 0.4mm of material between it and the motor face\n  to maintain proper plastic gear engagement.\n\u003c\/p\u003e\n\n\u003ch3\u003eWhat Is Drive Gear Runout and Why Does It Matter?\u003c\/h3\u003e\n\u003cp\u003e\n  Runout is the degree to which a rotating component deviates from perfect concentricity\n  as it spins. In a conventional dual-drive extruder, the main drive gear is a separate\n  component pressed or keyed onto a shaft — and even small manufacturing tolerances at\n  that interface create measurable eccentricity. As the gear rotates, its effective\n  diameter varies slightly, which translates directly into \u003cstrong\u003emicro-variations in\n  filament feed rate per revolution\u003c\/strong\u003e. These variations appear on printed surfaces\n  as subtle banding or inconsistency in extrusion width — a pattern that repeats at the\n  gear's rotational frequency and is notoriously difficult to tune away in firmware\n  because it originates in hardware geometry, not in the control system.\n\u003c\/p\u003e\n\u003cp\u003e\n  The IDGA solves this at the source. By machining the drive gear and shaft as a\n  single monolithic unit, there is no press-fit interface and no accumulated tolerance\n  stack — the gear runs as concentrically as the machine that produced it, which is\n  substantially better than any assembled equivalent.\n\u003c\/p\u003e\n\n\u003ch3\u003eIntegrated Shaft + Gear — One-Piece Precision Machining\u003c\/h3\u003e\n\u003cp\u003e\n  The core engineering of the IDGA is straightforward: instead of a shaft with a\n  gear pressed onto it, the entire assembly is \u003cstrong\u003emachined from a single billet\u003c\/strong\u003e.\n  Gear teeth, shaft, and bearing seats are all cut to final geometry in one setup,\n  which eliminates the eccentricity that arises when two separately manufactured parts\n  are assembled. The result is a drive gear that spins on its own axis with\n  significantly tighter concentricity than a conventional assembled gear — and\n  that consistency in rotation translates directly to consistency in filament feed.\n\u003c\/p\u003e\n\n\u003ch3\u003e5×8×2.5mm Ball Bearings — Included\u003c\/h3\u003e\n\u003cp\u003e\n  The IDGA requires \u003cstrong\u003e5×8×2.5mm ball bearings\u003c\/strong\u003e for correct installation\n  — these are included in the kit. These are precision-spec bearings matched to\n  the IDGA shaft dimensions. Using incorrect bearing sizes will affect shaft positioning\n  and negate the runout reduction the IDGA provides.\n\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBondtech\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eModel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eOEM IDGA Set (Integrated Drive Gear Assembly)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCompatible extruder\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eVoron Clockwork 2 (CW2) only\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFunction\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eReplaces main drive gear + shaft — reduces rotational runout\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eConstruction\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSingle-piece machined gear and shaft assembly\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRequired bearings\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e5×8×2.5mm (included)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eShaft length — bearing support\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMain gear side: 2.60 ±0.03mm — Filament teeth side: 2.60 ±0.03mm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFilament teeth center to shaft end\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMain gear side: 22.2mm — Filament teeth side: 5.60 ±0.04mm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMotor-face bearing clearance\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e~0.4mm (required for proper gear engagement)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAxial play\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eRequired in both directions — allows filament path self-correction\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003e✅\u003c\/td\u003e\n\u003ctd\u003e1× IDGA integrated drive gear and shaft assembly\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e✅\u003c\/td\u003e\n\u003ctd\u003e5×8×2.5mm ball bearings (quantity per Bondtech spec)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eWhat's NOT Included\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003e❌\u003c\/td\u003e\n\u003ctd\u003eSecondary drive gear — not supplied, retain from existing CW2 assembly\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e❌\u003c\/td\u003e\n\u003ctd\u003eSecondary shaft — not supplied\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e❌\u003c\/td\u003e\n\u003ctd\u003eSecondary needle bearings — not supplied\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e❌\u003c\/td\u003e\n\u003ctd\u003eCW2 printed parts — source from Voron GitHub\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eWhen Do You Need This?\u003c\/h3\u003e\n\u003cp\u003e\n  This is the right upgrade if you're running a Voron CW2 and seeing repeating surface\n  artifacts on prints that don't respond to pressure advance tuning, resonance\n  compensation, or temperature adjustments — the classic signature of drive gear\n  runout. It's also the correct move when building a new CW2 and wanting to\n  start from the best possible hardware baseline rather than troubleshoot later.\n  The improvement is described by Bondtech as \"slight\" — this isn't a dramatic\n  transformation, it's a precision refinement that targets a specific failure mode\n  in conventional gear assemblies. For builders who have already optimized every\n  other variable and are chasing the last few percent of surface quality, the IDGA\n  closes that gap at the hardware level.\n\u003c\/p\u003e\n\n\u003ch3\u003eResources\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n    \u003ca href=\"https:\/\/www.bondtech.se\/product\/oem-idga-set\/\" target=\"_blank\" rel=\"noopener\"\u003e\n      Bondtech OEM IDGA — official product page, setup guides, shaft dimension drawings\n    \u003c\/a\u003e\n  \u003c\/li\u003e\n  \u003cli\u003e\n    \u003ca href=\"https:\/\/github.com\/VoronDesign\/Voron-Stealthburner\" target=\"_blank\" rel=\"noopener\"\u003e\n      Voron Stealthburner GitHub — CW2 printed parts files and assembly documentation\n    \u003c\/a\u003e\n  \u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\n  Browse our full extruder upgrade selection at\n  \u003ca href=\"\/collections\/3d-printer-extruders\"\u003e3D Printer Extruders\u003c\/a\u003e, or explore all\n  Voron-compatible upgrades at\n  \u003ca href=\"\/collections\/3d-printer-upgrades\"\u003e3D Printer Upgrades\u003c\/a\u003e.\n\u003c\/p\u003e","brand":"West3D 3D Printing Supplies","offers":[{"title":"Default Title","offer_id":52735670681894,"sku":"BON2662","price":19.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1004\/1986\/2822\/files\/bondtech-oem-idga-set-west3d-3d-printing-supplies-bondtech-407629.webp?v=1773259449","url":"https:\/\/supplies3d.shop\/products\/bondtech-oem-idga-set","provider":"SUPPLIES3D","version":"1.0","type":"link"}
