• extrusion stops during printing

    This can be difficult to understand, because there are several possible causes. Here is a list of possible causes.

    • Is turning the motor of the extruder head? Use a marker to draw a line through the end of the axis visible in the rear of the engine. When the extruder is running, you should be able to see the rotation of the shaft. Sometimes it can change direction in order to retract filament, but during extrusion should move at a slow but steady pace. If it does not switch on or it does not rotate, please contact 3DCPI support and we will help you figure out what is going on.

    • Is tangled the filament? Check that the spool is rotating without problems in the holder.

    • Are you working platform too close to the extrusion head? If they are too close between each other, there may be no room for the plastic come out the extruder head. This is a likely cause if your extruder stops extruding during the first or second layer of printing.

    • Is the nozzle clogged? Run the routine of load filament from your machine. Observe the plastic as it emerges from the nozzle. It tends to fall down, or tends to curve toward the extruder? If it curves back toward the extruder, the nozzle may be partially obstructed. Contact 3DCPI Support and we will help you to get it fixed.

    Do not worry, this is normal! The 3DCPI printers use that line to purge the filament to two extruders to be always ready to start printing.


    If the first printing layers are detached from the building platform, it means the plate is not sufficiently close to the extrusion nozzles. Try leveling the plate again with a thin piece of paper or gauge to check the distance. It is important that every part of the plate is at the same distance from the nozzles - if part of your model take off, the rest can follow it.

    It's also a good idea to make sure that the plate is clean. Dust, hand grease, scratches and bubbles can prevent objects from sticking on the plate construction, so you should be cleaned regularly.3DCPI provide some double face adhesive cut as the platform of your machine, these adhesives are a good way to ensure adhesion of the first layer to the building platform.


    Try to expect the platform and the object to cool down. If the object is still stuck, use a putty knife or similar tool to gently pry between the object and platform construction. Carefully slide the spatula under the edge of the object, and then turn the handle.


    Execute the download menu to heat the extruder and open the lever arm of the extruder. Make sure the filament has a clean edge and no curves in it. Then push the filament into the hole in the top of the extruder. Keep pushing the filament until it starts to see the plastic out of the nozzle. You may have to push the filament pretty hard way.

    If the plastic does not emerge from the nozzle, remove the filament and check if there is a curve at the end. That could mean that the filament is sliding under the tread extruder instead of entering the heater. Use the instructions for removing the extruder in your owner's manual to remove the fan and heat sink so you can see the filament and make your way through the extruder.

    When the filament is loaded, be sure to close the lever arm of the extruder.Still having problems? You can always contact us at for more help.

  • + i cannot take out the filament of my extruder.

    Open the lever arm extruder and push a short length of filament through. Then try to take it out again. Repeat if is necessary.

  • my extruder remains hot after loading or unloading the filament

    If you have the menu PREHEAT activated, the extruder will not stop heating after loading or unloading the filament. To stop heating the extruder head, choose PREHEAT from the main menu and select OFF.

  • + my object is the wrong size.

    Sometimes the expected size of an object can be lost in translation between software design and slicing. Our software expected that the units will be established in millimeters, so make sure your modeling software is also established to work in millimeters. You can also use the scaling function in the software of the printer to scale an object of a specific size.

  • my extrusion nozzles are not aligned properly

    Check the Utilities menu from the interface LCD 3DCPI the routine calibrate nozzles. This script will print some test extrusions and allow your printer 3DCPI give some feedback so you know exactly where the two nozzles are related to each other.

  • my printer 3dcpi cannot see my sd card.

    If the printer 3DCPI does not recognize that there is a card in the SD slot, make sure that you are using a FAT16 formatted card SDSC not greater than 2 GB. If your card does not correspond to this description, the printer may not be able to read it. If the card has been formatted correctly, but the printer does not recognize it, the card may have some type of defect.

  • i cannot find my file on the sd card.

    If your 3DCPI recognizes that an SD card is present, but can not see your file, make sure the file is in the correct format. The printer 3DCPI can read files in the format x3g. To create a file x3g. In your Printer Software, make click in Export to a file and select X3G in the drop-down menu File Type.

    The printer 3DCPI can not read names longer than 26 characters - 30 characters if the file extension is counted. If you are trying to print a file x3g. With a long file name, shorten it and try again.

  • help! my printer makes unusual sounds.

    Check menus to ensure you have the throttle switching-on. Attempting to print at high speed with acceleration in mode off, may damage the printer 3DCPI. You can turn the throttle occasionally through General Settings in the printer 3DCPI through menus or through Preferences on board in your print software. The acceleration is enabled by default. If you have the acceleration off, should not print at higher speeds to 40 mm/s.


    Actually, not a lot! But if you have been printing for over fifty hours continuously or if you start hearing squeaking noises during construction of the parts, then it is probably time to lubricate the threaded shaft and pulley. You also need to place a new sheet of Kapton tape to the building platform and occasionally a new sheet of double-sided adhesive. Take advice of the user manual for instructions on how to do all those processes.
