This project began as a serial request for a Voron 2.4 running the Stealthchanger toolchanger system, and the goal behind it is simple: swap toolheads mid-print to get multi-color output out of a CoreXY machine. Six toolheads sit along a dock rail at the rear of the enclosure, each with a blue printed shroud, a direct-drive extruder, a filament feed tube, wiring, and status LEDs. They resemble the Stealthburner design and rest in a stationary rack, connected by translucent PTFE tubes carrying filament.
The frame measures 520x520x1100 and holds a 350x350x600 build volume, closed in with 3 mm aluminium panels, blue corner brackets, and clear side panels. The rear wall is lined with white brick-pattern foam, internal LED strips light the interior, and the textured PEI sheet carries a small label plate on its front edge. Under the hood there are UHP-500 power supplies, eight LDO speedy motors driving the moving gantry, and TMC 2208 drivers. Each toolhead is an A4t with a Dragon Ace Volcano hotend.
The path here was not straight. The machine first ran on 48V with a Kraken board, then the maker tried TMC 5160T Pro drivers, found them too noisy, and went back to TMC 2208 for now. The electronics started at the bottom and were later moved to the top. The Z axis runs 25:1 gearing instead of the original 5:1, which makes its motors work about five times harder than that setup would.
The results look convincing: a multi-color Voron calibration cube in purple, yellow, black, and white, printed beside a rectangular purge tower, with tool changes happening seamlessly. Two things remain open. The hotend's slow heating time is its only downside according to the maker, and the 48V supply is not connected at the moment while other future changes are being planned.
