Prusa 3D printer Hephestos is an open source 3D printer designed and developed by the bq Department of Innovation and Robotics. Hephestos is based on the Prusa i3 and adds several improvements to other printers like PowerCode. Parts were developed by the RepRap community with modifications and new parts added by bq.

This project has sought to offer a robust printer design, addressing many of the shortcomings of earlier designs such as end-stop positioning and wiring routing. We have placed particular emphasis on providing good documentation to facilitate its assembly.

Changes with respect to other models Prusa i3

Limit switch clamping:
Designed by the department specifically for this model.
Belt tensioners
Tensioner X axis identical to the Power Code. Tensioner Axis Ydownloaded from Thingiverse. http://www.thingiverse.com/thing:68185
Support for RAMPS
Designed by the department specifically for this model. Includes three anchors to collect the wires on one side through the use of a cable tie. Guiding the cables ensures the Driver heatsinks are not covered.
Support LCD
Designed by the department specifically for this model. The design has been inspired by http://www.thingiverse.com/thing:121640
Support Fan
Designed by the department specifically for this model.
Cable Carrier
Parts modified to include the cable carrier on all axis, avoiding pinching, cuts and catching the cable during axis movement.
Power supply
Laptop power supply
Extruder
Witbox extruder.
Frame
Official Prusa design modified. A recess has been added to the Y axis area to prevent friction which previously existed during the levelling of the base plate caused by the screw protruding. File:Frame&base Hephestos.dxf.zip
Printing volume
215x210x180 mm

Modified

X Axis carriage

The following changes have been made to the original carriage:
-Attachment to rewind Igus cable carrier at the top (above the bearings).
-Addition of a small cap to ensure contact with the limit of X axis (on the side, next to the linear bearing carriage below)

End of the X Axis motor

Added support material to the screw which adjusts the Z axis height.
-The base has been elongated to reduced the clearance of the nut thereby preventing the screw from moving.
-The screw hole has been shifted outwards to improve accuracy in the mechanical Endstop activation.

RAMPS support

Added three hooks. Each hook works by using cable ties to hold and collect all the cables connected to the RAMPS. By guiding the cables through the side and into the plate at the top left corner it facilitates cooling of drivers by not having cables directly above the heat sinks.

    Assembly:
  • Step A

  • Step B

  • Step C

  • Note: The two nuts at the end are to be tightened together. Use a nut wrench on the adjacent nut to assist. This way you can ensure that the nuts are securely fitted to the screw. Now by using the wrench as shown in the picture, crank the tensioner to the side to achieve the required tension when fitting the belt.

  • Printer adjustments

    Z Axis adjustment

    Before printing with your printer you must calibrate the screw that adjusts the height of the Z axis so that the extruder is at the correct height relative to the base. To do this, follow these steps:
    -Level the ends of the X Axis to the same height. Thread each axis manually until both are at the same height.
  • Step A

  • -Tighten the set screw as much as possible without excess force to the printed parts.
  • Step B

  • -Using the LCD control panel bring the extruder to the home position.
    Control > Move Axis > Auto home
  • Step C

  • Step D

  • Note: Make sure that the Endstop sensors are being activated correctly by their respective axes.
    -Set the position of the endstop sensor adjustment screws and repeat the previous step (bringing the Z axis to home position).
  • Step E

  • -If the adjustment isn't correct, repeat the previous step.
  • Step F

  • Levelling the plate

    Once Z Axis is adjusted, it is necessary to level the plate.
    Using the LCD control panel, start the levelling program.
    Control > Level plate
    The program moves the extruder to four points of the base, where you must adjust the screws on each corner, so that you can just pass a sheet of paper between the extruder nozzle and glass. There should be a slight feeling of resistance produced by the extruder pressing the paper down onto the glass plate.
  • Step A

  • Step B

  • Step C

  • Step D

  • Hot End obstruction

    If a blockage occurs in the Hot-End, follow the next step:
    You must heat the Hot End to 220 °C and insert the 0.4 mm needle into the nozzle until you see it come out the other end. Afterwards you must clean the needle of any plastic which may have stuck to it.

  • Hello world: Your first print

    If you followed all steps of this manual, you should have your Prusa i3 Hephestos ready to do its first print!
    First you need to find a 3D design in .stl format for printing. Then you need to slice the chosen 3D design. For this, you can follow our guides of the most common used programs.

    Note: Remember that Prusa i3 Hephestos printing area is 215x210x180 mm.


    Once you have the g-code file, save the file on an SD card. Insert the SD card into the LCD control panel slot. In the main menu select "Print from SD". Now select your g-code file. The printer will start automatically. You can view the progress of the part and the extrusion temperature on the LCD panel of the printer. When printing is completed, remove the glass base by removing the clamps. With the base resting on a table, remove the parts by pulling on them firmly.
    You need to apply hairspray to the glass for better adhesion of parts!

    Firmware

    Follow the next steps to update the firmware:

    1. Download the firmware. In the RepRap wiki you can find a entire list of available firmwares:

       Link: http://reprap.org/wiki/List_of_Firmware
    

    2. Here are some of the most popular firmwares and our modification of Marlin:

           Marlin: http://reprap.org/wiki/Marlin
           Sprinter: http://reprap.org/wiki/Sprinter
           Marlin Hephestos: File:Marlin Hephestos.zip
    

    3. Download and install the Arduino software from their main site:

            Link: http://www.arduino.cc/en/Main/Software
    

    4. Inside of the firmware folder, you must open the .ino file with the Arduino IDE.

    5. Once open, a tab called "configuration.h" will appear. In this file you can configure the parameters of your printer.

    6. When you complete configuration, upload the program by selecting "Arduino Mega" from the list of boards and clicking the upload button.

    This step must be repeated with all drivers, you will need two motors for Z Axis driver calibration.


    Intensity for each Driver:
    Driver Intensity (mA)
    X Axis 250
    Y Axis 250
    Z Axis 450
    Extruder 680
    Arduino with RAMPS aprox. 74 (not regulable)

    Wiring

    It is necessary to connect one endstop sensor and thermistor, because of firmware firewalls.

    Multimeter preparation

    Connect the multimeter in serial connection between Arduino and power supply. Put multimeter in intensity measurement mode.

    Multimeter adjustment

    Connect the Arduino Mega to the computer. The flowing current is 74 mA approximately (this may differ between plates). Open Pronterface, select the correct port and connect to Arduino.

    You must move the motor using Pronterface interface. Measure the current and regulate this using the Ceramic screw trimmer together with the mulitmeter. The current should be set to the sum of the current circulating in the PCBA and the current in the motor. For example, in X Axis current must be 74 mA + 250 mA = 324 mA.

    Pre-heat or send the M302 command for completing the extruder calibration.

    Arduino needs to be reset before calibrating the next driver.
