This kit bundles every electrical and wiring\n  component needed to bring your Rev.A machine fully up to Rev.C spec — without buying a\n  new printer kit.\n\u003c\/p\u003e\n\n\u003cp\u003e\n  ⚠️ \u003cstrong\u003eThis kit is for LDO Voron V2.4 Rev.A owners upgrading to Rev.C only.\u003c\/strong\u003e\n  It is not a standalone build kit and does not include structural, motion, or printed parts.\u003cbr\u003e\n  ⚠️ \u003cstrong\u003ePrinted parts for Stealthburner and Clockwork 2 are NOT included.\u003c\/strong\u003e\n  You will need to print the Rev.C toolhead parts before installing this kit.

Rev.C introduced the\n  \u003cstrong\u003eStealthburner + Clockwork 2 toolhead\u003c\/strong\u003e as the new standard, replacing\n  Afterburner entirely. With it came a redesigned two-piece PCB system — a main Toolhead PCB\n  that mounts to the CW2 extruder body and a Fan Adapter PCB that mounts directly to the\n  5015 blower fan — which connects via a single 14-pin cable to the controller, dramatically\n  simplifying toolhead wiring and serviceability. The upgrade also brought in Neopixel support\n  for the Stealthburner LEDs, a dedicated chamber thermistor, and the BTT PiTFT43 as the\n  official display. This kit gives you all of that in a single order.\n\u003c\/p\u003e\n\n\u003ch3\u003eUpgrade Cable Kit — Everything the Rev.C Wiring Harness Adds\u003c\/h3\u003e\n\u003cp\u003e\n  The Rev.A wiring harness lacked circuits for features that didn't exist yet.
