Common Issues and
Troubleshooting
Filament is not extruding
The possible issue may be that either the hot end temp wasn't set to 15 for ABS or 195 for PLA
and/or the lament wasn't being pulled down into the extruder. If the lament is still in the hot
end, heat up the hot end to 15 for ABS or 195 for PLA degrees and then open the top latch on
the extruder and pull the lament out.
Check the small grooves in the hobbed bolt where the extruder goes into the hot end. The
grooves may be clogged with lament as this happens when the temp isn't hot enough and
then the lament just ends up grinding against that hobbled bolt. Use an Exacto knife to clean
out all of the grooves completely. Then snip off the end of the lament at an angle and push it
down into the hot end with medium pressure and you should see it extrude out the bottom.
Just make sure that your hot end temp has reached 215 for ABS or 195 for PLA before doing
this. You can click on the temp graph in Repetier to view the current temps.
If you see lament coming out the bottom when manually pushing, pull out the lament, re-
trim the tip, and then feed the lament between the two long bolts on the top latch down into
the extruder hole where the hobbled bolt is. Then close the top latch to lock it into place.
Make sure your computer is connected to the printer and that you are connected in Repetier.
Then click on the manual extrude button to make sure it comes out.
Print not sticking to bed
We recommend using common masking tape when printing PLA. Be sure that the tape is
covering your desired printing surface. If the print is still not sticking, try lightly sanding the
masking tape with a ne grit sand paper.
Head is dragging across the print
If the nozzle seems to drag through the plastic of the previous layer as it is printing then first
check to be sure that the thermal wrap on the print head is secure and is not hanging below
the level of the nozzle. If it is then slide it up slightly so that it is clear of the print surface. Be
careful, if your heater is turned on then it will be hot! Make sure there is no plastic debris on or
around the nozzle that may have been left over from a prior print -- even a small piece of plastic
stuck to the side of the nozzle can ruin a print.
