This is a detailed guide on how to design, assemble, and configure a custom print head for a 3D printer. The guide covers the following topics: 1. Design: * The author's starting point was a design suggested by Big-Bert. * The design allows for nozzles to be kept close together. * A 40mm x 40mm x 20mm 12V 0.24A fan is added to cool down heat-sinks and filament. 2. Assembly: * Holder things are used to allow the hot-end to slightly move up and down when screws are not tightened. * The print bed is leveled using one hot-end, and then adjusted for the second hot-end. * LEDs are soldered to resistors outside Duct_with_LEDs or LED_holder thing, and inserted into holes. * Wires are passed through channels in the main thing to hide them from view. 3. Configuration: * Marlin settings: + X_MAX_POS 210 + Y_MAX_POS 193 + Y_MIN_POS 0 + MANUAL_X_HOME_POS 210 + MANUAL_Y_HOME_POS 193 * Repetier Host settings: + Printer Settings -> Printer -> Park Position: X: 210, Y:193, Z min: 0 + Printer Settings -> Printer -> Extruder -> Extruder 2: Offset X: -23, Offset Y: 1 + Printer Settings -> Printer -> Printer Shape: X Min: 0, X Max: 210, Bed Left: -28.7, Y Min: 0, Y Max: 193, Bed Front: 0 * CuraEngine settings: + Print -> Extrusion: Enable Retraction checked, Retraction speed: 70 mm/s, Retraction distance: 4 mm, Minimum distance before Retract: 0.2 mm, Minimum extrusion before Retract: 0.02 mm The guide also mentions that the author's design uses every available millimeter of space and requires the use of Glass Holders to utilize the entire 210mm x 193mm area. Note: The guide assumes that the reader is familiar with 3D printing and has a basic understanding of Marlin, Repetier Host, and CuraEngine settings.
