Q: The idle nozzle scratches the printing model while single colour printing
A: 1. The height of the idle nozzle is too low, turn it up.
Please move the build platform to the top of Z‐axis, adjust the height of two nozzles according to the gap
between the print head and the platform, tighten the idle nozzle by wrench and make it a little bit higher
than the other one.
2. The printing flow is too high, causing the actual layer thickness is higher than the original setting, after a
while, the object is over high and touch the main nozzle.
Please turn down the printing flow.
Hardware Problems
Feeder and Extruder Problems
Q: Nozzle clogged
A:1. There is the impurity in the filament, which is stacked in the nozzle. Please clean the nozzle by the
needle; or take the nozzle off and clean inside of the nozzle by needle and drill.
Note: If the Teflon filament tube has been grinding on the filament extruder gear there is a good chance that
small pieces of Teflon will contaminate the tube. The Teflon will not melt and will block the nozzle! If this
occurs you will need to remove the nozzle and blow out the any contamination from the tube.
2. The nozzle is overheated causing the filament carbonized inside. Please clean the nozzle by needle; or take
the nozzle off and clean inside of the nozzle by needle and drill.
3. The deformation of the nozzle hole occurred by external force. Please replace the nozzle.
Q: The nozzle heating failed
A: 1.The heating tube connection is too loose. Please tighten the connection.
2. Heating tube/ temperature controller/ power tube damage. Please check if one of the nozzles works well,
but the other one cannot be heated, please troubleshoot by the following methods:
1) Open the machine case, and find out the connectors of two heating tubes, exchange the two connectors,
heat the nozzle again. If the failed one can work now, it means one heating tube is
broken and needs to be replaced;
2) If after exchanging the two heating tube, the failed nozzle still can't work, please exchange the heating
tubes back, and try to exchange the connection of the two temperature controller, heat the nozzle again, if
the failed nozzle can work, it means one temperature controller is broken and needs to be replaced;
3）If the above cannot solve the problem, it means it should be the problem of the power tube on the main
