Trouble Shooting
Q1 The model can’t stick to the hot bed
Solution 1: Adjust Z0 height after Auto-levelling, until the height between nozzle and hot
bed is the thickness of one layer of A4 paper.
Solution 2: Heat the hot bed to 60°C, then wipe the lattice platform with water or alcohol
to remove grease and dust.
Solution 3: Add brim the model or rise the temperature of the hot bed in the slicer
software.
Q2 The filament doesn’t go easily into extruder
Cut the end of the filament into an oblique, straighten the head of the filament, and use
automatic feeding. When the extruder starts working, push the filament by hand.
Q3 The filament cannot be pulled out from the extruder smoothly when you
change it
Solution 1: Pull out the PTFE tube from the extruder, then pull out the filament from the
extruder.
Solution 2: If the PTFE tube has been deformed please change the PTFE tube first, insert
the new PTFE tube till bottom, and tighten the pneumatic connector with the locking clip,
then push the new PTFE tube until it doesn’t go further.
Q4 Nozzle clogging
Solution 1: Heat the nozzle to 220°C, then clean the nozzle with the nozzle cleaning
needle
Solution 2: Heat the nozzle to 240°C, then click “Tools>Change>In” to use automatic
feeding, to see if there is any filament extruded from the nozzle.
Solution 3: Clean the extruder gear and remove the filament fragment.
Solution 4: Change the nozzle module and cut the PTFE tube to a flat end and insert it to
the bottom as far as possible
Q5 Poor printing surface quality, with spots and wire drawing
Solution 1: Check if the linear guide and not parallel arm are loose and well lubricated.
Solution 2: To cut the PTFE tube to a flat end, heat the nozzle to 220°C, then re-insert the
PTFE tube to nozzle module as far as possible.
Solution 3: Clean up the remaining filament debris on the extruder gear.
