The 8-tooth motor gear — rather than the more common\n  9T or 10T used in other LDO extruder applications — is the specific tooth\n  count that optimizes the torque-to-speed balance for the Jabberwocky's\n  filament changing unit (FCU) use case: enough torque to reliably load and\n  unload filament through the rapid cycles of multi-material printing, at a\n  speed that keeps transitions fast. Using a motor with a different tooth count\n  would shift this balance and require firmware-level compensation.\n\u003c\/p\u003e\n\n\u003ch3\u003eNEMA14 Round Pancake — 36mm Diameter, 20mm Body\u003c\/h3\u003e\n\u003cp\u003e\n  The 36mm round (pancake) NEMA14 form factor is the standard for lightweight\n  direct-drive toolhead motors — smaller frame than NEMA17, shorter body than\n  most NEMA14 variants, and compact enough to mount directly behind the extruder\n  without adding significant mass to the toolhead. The \u003cstrong\u003e20mm body\n  length\u003c\/strong\u003e keeps the Jabberwocky's overall depth manageable for toolhead\n  mounting across a range of printers. The motor runs \u003cstrong\u003esignificantly\n  cooler than NEMA17 equivalents\u003c\/strong\u003e at the same torque output — an important\n  consideration in the enclosed chambers where the Jabberwocky is typically deployed.\n\u003c\/p\u003e\n\n\u003ch3\u003eClass H 180°C Insulation — Built for Hot Chambers\u003c\/h3\u003e\n\u003cp\u003e\n  Standard extruder motors use Class B insulation rated to 130°C. In an enclosed\n  printer running ABS or ASA at 60–70°C chamber temperature, with the motor\n  mounted close to the hotend and running at sustained current, the winding\n  temperature can approach or exceed the Class B ceiling. The\n  LDO-36STH20-1004AH(IG8T) uses \u003cstrong\u003eClass H insulation rated to 180°C\u003c\/strong\u003e\n  — a 50°C safety margin over Class B — giving the winding insulation real\n  headroom in demanding enclosed environments. Maximum recommended operating\n  temperature for sustained use is 120°C at rated current (1.0A), or higher\n  at reduced current.\n\u003c\/p\u003e\n\n\u003ch3\u003eIntegrated Gear — Factory Pressed, Zero Backlash\u003c\/h3\u003e\n\u003cp\u003e\n  The 8-tooth gear is \u003cstrong\u003efactory-pressed onto the motor shaft\u003c\/strong\u003e\n  as a permanent assembly — not a separate component that slides on and is\n  secured with a set screw. Factory pressing eliminates the gear runout and\n  backlash that accumulates over time in press-fit or set-screw gear assemblies,\n  maintaining consistent filament feed rate through thousands of load\/unload\n  cycles. The integrated design also means there's no set screw to loosen\n  under vibration — a failure mode that causes inconsistent extrusion in\n  high-cycle multi-material workflows.\n\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eManufacturer\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eLDO Motors\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eModel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eLDO-36STH20-1004AH(IG8T)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCompatible toolhead\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eJabberwocky (all versions — Assembled, Standard, Basic)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFrame size\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eNEMA14 — 36mm round (pancake)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBody length\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e20mm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eStep angle\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1.8° (200 steps\/revolution)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRated current\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1.0A per phase\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePhase resistance\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2.1Ω ±15%\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePhase inductance\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1.6 mH ±20%\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eHolding torque\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e100 mNm minimum\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eIntegrated gear\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e8 teeth (IG8T) — factory pressed\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eShaft diameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2.5mm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInsulation class\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eClass H — 180°C rated\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMax operating temp (rated current)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e120°C\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e~70g\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWiring\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eIntegrated 1m high-temperature Teflon wire\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× LDO-36STH20-1004AH(IG8T) motor with 8T integrated gear\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e✅\u003c\/td\u003e\n\u003ctd\u003e1m integrated high-temperature Teflon wire harness\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  Order this as a replacement if your Jabberwocky motor has failed — whether from\n  electrical damage, overheating from sustained over-current, or physical damage\n  from a toolhead crash.
