on the top right of the filament drive. Loosen this screw using an Allen wrench until the gap
on the top of the filament drive is approximately the width of a business card.
PRINT QUALITY
Problem:
Print stops without finishing
Probable Cause 1:
Improper slicing of CAD design.
Remedy
: Re-slice the CAD model using the slicing software. First, re-slice using basic
settings. Save the re-sliced g-code file onto the SD card and attempt to print. If this does not
work, re-slice using advanced settings. If print still stops without finishing, the SD card may
be corrupt.
Probable Cause 2:
Corrupt SD card.
Remedy
: If re-slicing the CAD model does not resolve the issue, the SD may be corrupt. Save
the g-code file to another SD card and re-print.
Probable Cause 3:
Loose power connector.
Remedy
: Verify that the power cord is completely plugged into the back of the printer. Check
the wire that connects the power plug breakout board to the RAMBo board and verify that
the ends are completely inserted. The six pin connector may be inserted at an angle so that
all contacts are not hitting.
Problem:
Print shifts while printing
Probable Cause 1:
Print board moved.
Remedy
: The print board may be loose and shifted. Stop the print, remove the print board,
and remove the part. When inserting the print board, ensure that it seats all the way into the
rear clamps. Push the front clamp tight against the front of the board and lock it into place
with the blue thumbscrew. Attempt to wobble the board slightly to verify that the print board
is locked in place. Attempt the print again.
Probable Cause 2:
Hot end moved.
Remedy
: Observe the print to see if the hot end is loose. If so, stop the print and tighten the
small black thumbscrew at the front of the hot end assembly which will lock the hot end in
place. Remove the part and attempt to print again.
Probable Cause 3:
Improper slicing of design.
Remedy:
Re-slice the CAD model and save on SD card. Use the basic slicer settings with re-
slicing; advanced settings can be used once the problem has been identified. Remove the bad
print from print board and re-attempt the print using the re-sliced g-code file.
Probable Cause 4:
Gear attached to motor drive shaft or belt is loose.
Remedy:
Release the tension on the belt. Loosed the two set screws with Allen wrench.
Rotate the gear so that one set screw aligns with flat side of motor drive. Retighten set screws
and belt.
