Comprises three (almost) identical linear actuators built around C-beams with machined end caps

All mechanics are maximally over-engineered to compensate for a poorly conceived and inherently unstable gantry design.

• endplates are machine 8mm aluminium
• transition fit for NEMA17 motor journals
• press fit for flanged bearings
• 3 NEMA17 steppers with integrated ~500mm leadscrews
• all 3 axes differ in gantry plates only, but use otherwise interchangable components

• dual head
• 1.75mm bowden extruders (Titan from E3D)
• internal air guide creates a directed planar sheet of air
• printed ABS duct for better heat resistance
• flexible TPU adapter improves fan connection to the duct

• print area is 360x360mmm

• bakelite heated bed
• overengineered kinematic mounts: machined, hardened, and surface ground V-Blocks locating on cap screw heads :D

• machined from 6mm aluminium, heater fully recessed
• removable magnetic print surface from Ender 5 Plus
• rigidly bolted to the X gantry to reduce vibrations

• Duet 2 WiFi controller
• 350W power supply
• custom laser-cut enclosure
• NC emergency switch
• NO customizable control buttons
• NO reset button (unfortunately, Duet 2 uses a dedicated pin for that, so has to be hard-wired)

Homing is done switch-less using stall detection.

Currently done by detecting contact between print head and a steel feeler gauge :D

• G29.1 allows loading an interpolated height map for a given temperature using RepRap firmware support for "meta-commands".

triggerX.g allow customizing button actions, e.g. the "Green" button will resume print if paused, or print last file again if not currently printing.

load.g/unload.g provide parametrized macros to simplify filament management.
