Initialization

fab = createFab()

p5.prototype.createfab = function() {
  _fab = new fab();
  return _fab;
};

Creates a fab object, defaulting to the values with the Ender 3 Pro, which allows control of the 3D printer.

createCanvas(windowWidth, windowHeight, render)

A p5 function that creates a canvas object with the set dimensions in pixels.

createButton(description)

let buttonConnect = createButton('connect to printer');
let buttonHeat = createButton('heat nozzle');
let buttonPrint = createButton('Print');

Creates HTML web buttons that allow users to interact with the 3D printer without needing to code.

Controlling the Printer

fab.heatNozzle()

Homes and then heats the nozzle to 200 degrees Celsius.

fab.coolPrinter()

Sets the nozzle temperature to 0C and returns the printer to the default home position.

fab.autoHome()

Moves the 3D printer to the home position by first calling the auto home G-Code value (G-Code: G28) followed by zeroing and stopping of filament extrusion (G-Code: G92 E0).

fab.move(x, y, z, v)

Allows the movement of the 3D printer nozzle to a specified position with a specified velocity

X: the X position of the nozzle

Y: the Y position of the nozzle

Z: the Z position of the nozzle

V: the velocity (mm/s) at which the nozzle travels to the specified location

fab.setNozzleTemp(temp)

Takes a temperature in Celsius and sets the nozzle temperature to it (G-Code: M109).

fab.setBedTemp(temp)

Takes a temperature in Celsius and sets the bed temperature to it (G-Code: M109).

fab.print()

Prints.

fab.moveExtrude(x, y, z, v, e)

Moves the nozzle to a specified position while extruding filament.

X: the X position of the nozzle

Y: the Y position of the nozzle

Z: the Z position of the nozzle

V: the velocity (mm/s) at which the nozzle travels to the specified location, defaults to 1500 mm/s

E: the amount of filament that has been extruded so far, defaults to makeE(x, y).

fab.makeE(x, y)

Takes the coordinate position of the nozzle and returns a calculated amount of filament extruded.

fab.presentPart()

Moves the nozzle to the side and extends the bed out so that a user may retrieve the print.

fab.setAbsolutePosition()

Sets all axes to absolute positioning. All coordinates are interpreted as positions in the logical coordinate space (G-Code: G90).

fab.setRelativePosition()

Sets all axes to relative positioning. All coordinates are interpreted as relative to the last position (G-Code: G91).

fab.ERelative()

Overrides fab.setAboslutePosition() and puts the E axis into relative positioning, independent of other axes (G-Code: M83)

fab.fanOn()

Sets the print cooling fan to full speed (G-Code: M106).

fab.fanOff()

Turns the print cooling fan off (G-Code: M107).

fab.pausePrint()

Pauses the printer after the last movement and waits for user input to continue (G-Code: M0).

fab.stopPrint()

Stops the printer by clearing all the commands queued.

fab.introLine()

Prints a single line along the left side of the printer bed in order to clear the nozzle before the actual print begins.

fab.waitCommand()

Pauses G-Code processing until all moves in the printer queue are completed (G-Code: M400).

fab.getPos()

Retrieves the current position of the active tool (G-Code: M114).

fab.autoReportPos(t)

Sets an interval and sends current position of active tool automatically (G-Code: M154).
