D3D Universal Startup Procedure

​

  1. Plug in all the wires
    1. Plug in 4 stepper motors
    2. Plug is 3 endstops
    3. Plug in thermistor
    4. Connecte 5V to RAMPS
    5. Connect 120V to power supply
    6. Connect 24V to RAMPS
    7. Connect blower, fan, and heater
    8. Connect LCD
    9. Connect power to GFCI
  2. Reset the GFCI - and this powers the system on
    • Check that LCD turns on and thermistor is reading room temperature
    • Check whether the fan turns on
    • Check whether Z probe light turns on when a metal object is placed by the probe
      1. With all this done - you have verified that Z probe, fan, and thermistor are functioning
  3. Go into Menu and Control and turn on the extruder heater
    • Observe if temperature of extruder rises. Set temp to 230C.
    • Observe if Move Axis -> extruder is working, such that extruder extrudes (not retracts) when positive extrusion is selected.
  4. Go into menu, and do Prepare-> Home Axes. This tests motion and endstops
    • Keep hand on reset button, and observer for correct motion. Correct motion means motion towards endstops
    • If motion is reversed, click reset and reverse Dupont connector. Try again. Shake down the X, Y, and Z in this manner
    • After motion is correct, you are ready for the first print.
  5. Upload a file to the SD card, and do a test print
    • Upon first print, go to Menu->Tune->Babystepping correction
    • Correct the first layer height. Touch the print, and observe whether it is more or less flat with the surface. You can do a tactile test or visual inspection for layer height
  6. You’re done! Finish print and observe result - such as flatness of first layer (no lines visible, it’s smooth against the print bed)

D3D Universal Troubleshooting

​

  • General
    • For wiring, check power first. Then check plug, wire, and last, the component that is not working. The first issue is most common.
  • Motors chattering
    • Check plug so all 4 wires are plugged in
    • Check if wires are crossed, repin if needed
    • Check cable - replace a cable with a working one
    • Check motor - replace motor with a working one
  • Axis not moving when motor is spinning
    • Loose pulley
    • Belt loose
  • Endstops not triggering
    • Check that signal wire is on top when plugged in
    • Check endstops are plugged in to the correct location
    • Check that there is no mechanical obstruction preventing lever from triggering
    • Probe not triggering - check it with metal object for light coming on
  • Thermistor not reading correct temperature
    • If 0 - plug it in or check wire
    • If max temp - it’s got a short, replace it
  • Power supply not lighting up
    • Check wire
    • Check supply - plug power wires into a working power supply
  • LCD not lighting up
    • Check that plug 1 and 2 are not reversed
