Troubleshooting Guide

 

Issue/Title The Printer Doesn't Move
Cause 1   The connector of the X,Y, or Z axis getting loose.
Suggested Solutions 1 Press the home key and see the bed will move or not. Check the connector of the X,Y and Z axis and make sure they are all connected. Re-connect it if the connector don't connect.
Example Image / Graphic
Cause 2   The filament didn't get into the nozzle.
Suggested Solutions 2 Press the "+" key, after some fast flashing it will flashes slowly. Press the filament into the nozzle, and you can see the filament will come out from the nozzle.
Example Image / Graphic
Cause 3
After press the play key, it will flashes for about 1 minute and then it will start to move. If the green light doesn't flashes, the files in the SD card may not recognized by the printer.
Suggested Solutions 3
1. Check the files are printable for this printer (printing size).                  2. 2. Check the files in the SD card are in GCODE file and doesn't have any special characters.                                                                                      3. Format the SD card into FAT32 and copy the files into the SD card again.                                                                                                             4. You can use the default file "rocket" to test if it is files issue or not.

  1. Disable layer cooling
Cause 3 Ambient air temperature is too cold and uneven
Suggested Solutions 3
  1. Use an enclosure, e.g. cardboard box or shower curtain to control environment
Cause 4 Printer is printing too fast
Suggested Solutions 4
  1. Decrease print speed
Issue/Title Shifted layers or leaning prints
Example Image / Graphic
Issue Details Layers shift in the z-direction as print progresses
Cause 1 Printer is printing too fast
Suggested Solutions 1
  1. Lower printing speed
Cause 2 There are loose pulleys on the x-axis and/or y-axis
Suggested Solutions 2
  1. Make sure there is no “play” in the pulleys and tighten
  2. Check to see if there is friction on the pulleys and adjust
Cause 3 Belts are skipping teeth on the x-axis and/or y-axis
Suggested Solutions 3
  1. Check for friction along the entire axis
  2. Check that belts are tight and adjust tension screw

 

Issue/Title Stringing / hairy prints
Example Image / Graphic
Issue Details Filament in the hot end of the extruder continues to ooze out of the nozzle during non-print moves

Cause 2 Filament extrusion temperature is too low
Suggested Solutions 3
  1. Increase extruder temperature
Cause 3 Nozzle or extruder may be clogged or not properly calibrated
Suggested Solutions 3
  1. Check that the filament path is clear
