2. Filament diameter is too large,causing filament jammed inside teflon tube: Make
sure filament diameter is within 1.75±0.1mm. Replace with new filament if not fit.
3. Part of the filament is cracked inside the throat tube or teflon tube when plugging
out the filament after print finished or change filament:
Disassemble the extruder,clear and unclog the whole parts including teflon tube,throat
tube,extruder motor and nozzle.
4.False operation — directly insert the filament into extruder without cutting off the
melted tip part when reload in filament:Clear out the jammed filament fragment by
heating extruder and pushing the pin tool,replace the new filament,making sure
filament tip is smooth,not deformed or twisted.
5.Teflon tube is totally out of shape or the nozzle is totally jammed, these parts can not
be used any more: Replace with new teflon tube or new nozzle.

and the copper sleeve do not coordinate: Check these parts, disassemble and
re-assemble these parts to check again, Replace corresponding problem parts with new
parts.
3.Z-Axis driver board has problem: Replace the Z-Axis driver board with the normal
X-Axis driver board or normal Y-Axis driver board (mind driver boards’ directions) , if
