Putting on the Extruder PDF Print Email

If you need to assemble the cold end of the extruder, you will need :

  • 3x M3 Nuts
  • 2x M4 Nuts
  • 1x M8 Lock Nut with Nylon Insert
  • 6x M3 Washers
  • 2x M8 Washers
  • 3x M3x10mm Cap Screws
  • 2x M3x40mm Cap Screws
  • 1x M3x8mm Grub Screw
  • 2x M4x20mm Cap Screws
  • 1x M8 Hobbed Bolt
  • 1x 8mm Smooth Rod, 18mm Length
  • 1x Small Spring
  • 3x 608ZZ Skate Bearings
  • 1x NEMA 17 Stepper Motor
  • 1x Assembled MakerGear Hot End
  • 1x Hot End Mounting Plate, Wood
  • 1x Hot End Mounting Plate Circle, Wood
  • 1x wades-small printed piece
  • 1x wades-large printed piece
  • 1x wades printed piece with idler

 

If your cold end of the extruder is already assembled, you will need:

  •  2x M4 Nuts
  • 2x M4x20mm Cap Screws
  • 1x Assembled Cold End of the extruder
  • 1x Assembled MakerGear Hot End
  • 1x Hot End Mounting Plate, Wood
  • 1x Hot End Mounting Plate Circle, Wood

 

In this part you will be assembling the extruder if you need to and putting it onto the x-carriage.  You will need a 2.5mm allen wrench to tighten the M3 cap screws into the motor, a 1.5mm allen wrench to tighten the grub screw, a 3mm allen wrench to tighten the M4 cap screws, and a 13mm wrench to tighten the M8 lock nut.  If your cold end is already assembled, you will only need a 3mm allen wrench for the M4 cap screws.  This is what the x-carriage will look like with the extruder on:

Putting on the Heatbed PDF Print Email

For this part you will need:

  • 9x M3 Nuts
  • 15x M3 Washers
  • 3x M3x40mm Cap Screws
  • 3x 3+mm Inside Diameter Springs
  • 1x Prepared heatbed assembly (wires, LEDs, resistor, thermistor)
  • 1x 8 inch x 8 inch, 1/8" thick piece of glass
  • 4x Small Binder Clips

 

In this step, you will be putting the heated bed onto the bed that you put on along with the y-axis.  Your heatbed should already be put together and ready to put on before this step.  This means that it already has the resistor, LEDs, and wires soldered to the board and thermistor.  The thermistor and wires should also be taped to the board.  You will need a level to make sure the bed is level.  Once the bed is on, it will look like this:

Attaching Endstops PDF Print Email

For this part you will need:

  • 2x M3 Nuts
  • 2x M3x16mm Cap Screws
  • 2x Small Zip Ties
  • 3x Mechanical Lever Switch
  • 1x y-enstop-holder printed piece
  • 1x minimal-endstop printed piece

 

Optional, if not gluing an endstop to the x-end-motor piece

  • 1x M3 Nut
  • 1x M3x16mm Cap Screw
  • 1x Small Zip Tie
  • 1x minimal-endstop printed piece

 

This part will be fairly easy, you will only be attaching the endstops and getting them ready to hook up.  You'll need a 2.5mm allen wrench to tighten down the cap screws again.  You will also need some glue to attach the x-endstop to the x-end-motor piece, which will give you maximum printing space.  If not, you will need the optional items above.  This is where you'll be after this step:

Wiring and Cable Management PDF Print Email

For this part you will need:

  • 6x 26-22 AWG Insulated Quick Disconnect Terminals
  • ~3 feet of 18 AWG Wire, 2 conductor
  • ~6 feet of 24 AWG Ribbon Wire, 2 conductor
  • 9x Small Zip Ties
  • 5x 2-pin header connectors
  • 5x 4-pin header connectors
  • 2x  2-pin Male molex connector for the hot end
  • 4x Female Pins for the hot end
  • 30x Female Pins for header connectors
  • 7x M3 Nuts
  • 7x M3 Washers
  • 4x M3x16mm Cap Screws
  • 3x M3x25mm Cap Screws
  • 1x RAMPS 1.4 Electronics
  • 2x ramps-mount-bar printed pieces
  • 2x ramps-mount-clamp printed pieces

 

This part will consist of creating the wires that run to the endstops, the motors, and cleaning them up a bit.  Ideally you would want to use pin crimpers to put the pins onto the ends of the wires, but you can just use a pair of pliers if you are careful and don't want to buy a new tool.  You will also need something to cut and strip the wires with.
