Probable Cause 2:
Wrong print board material.
Remedy
: If not using BuildTak material, there may be increased part warping. If using
blue painters tape, try to re-level the print board to move the hot end slightly closer to
the tape, although this may not completely correct problem. It is recommended that
BuildTak be used to improve part quality.
Probable Cause 3:
Print board not level.
Remedy
: If a part is warping in one particular place, the print board may not be level.
Stop the print, remove the part, and allow the hot end to cool down, then level the board.
Initiate a print to verify that the problem has been corrected.
Problem:
Print is stringy and/or messy
Probable Cause 1:
Filament is poor quality.
Remedy:
Verify that high quality filament from a recommended supplier is being used.
Cheap filament is very stringy and does not retract well as compared to high quality
filament.
Probable Cause 2:
Hot end temperature too high
Remedy
: The hot end temperature may be set too high. It is not recommended to print
at a temperature greater than 225°C. If this does not remedy the problem, the thermistor
may be faulty.
Probable Cause 3:
Hot end needs replaced.
Remedy
: Submit a Support Ticket to order a new hot end.
Problem: Print quality is not good
Probable Cause 1:
Improper slicing.
Remedy
: The printer part may have been improperly sliced. Re-slice the part using the pre-
programmed, default settings which can be found at
www.inventorcloud.net
and re-attempt
the print.
Probable Cause 2:
Part geometry not conducive to 3D printing.
Remedy
: Certain part geometries result in poor quality when 3D printed. Verify that part
geometry is conducive to 3D printing. Many designs downloaded from the Internet will not
print properly and should not be used. If unsure if the part geometry can be 3D printed,
submit a Support Ticket for assistance.
LCD
Problem:
LCD displays only blue screen
Probable Cause:
Wiring backwards from LCD to RAMBO board.
Remedy
: Disconnect power from the printer and remove the top cover to access the RAMBo
board. Ensure that the LCD wires are plugged into the correct ports on the RAMBo board.
The LCD wires should cross once if properly plugged in, meaning that the right wire plugs
into the left port on the RAMBo board and vice versa. Check that the wires are plugged into
