Unlock the Cartridge → Remove the Cartridge from the Printer → Go to Setting - Extruder mode and Press "100" as the transfer length and Press the arrow directed away from the Nozzle to remove the Filament completely from the printer.
→ Remove the Filament that is sticking out of the Cartridge(refer to the image below), Reassemble the Cartridge and begin loading the filament. If Notification 476 Occurs, Press "No" and repeat the loading process.
Cutting Filament Tip
- When the ends of the Filament is sharp and acicular filament will run through easier.
- Go to Setting - Extruder mode. Press "100" as the transfer length and Press the arrow directed towards the Nozzle.
Please make sure that the Filament is completely excreted from the Nozzle (If the Filament does not excrete from the Nozzle, Please Contact the Customer Service)
- Readjust the gap between the Bed and the Nozzle
1) Remove the debris near the end tip of the Nozzle.
2) Execute Setting - Bed Leveling
3) Go to Setting - Z offset Menu to check and adjust the gap.(http://3dprinter.sindoh.com/VideoTutorial → refer to the 3DWOX Z Offset Setting video)
Press "Move" to adjust the gap between the Nozzle and the Bed and make sure that a paper with a thickness of 0.25 mm (Thickness of a Business Card or two sheets of paper folded) can pass through the gap. The optimal gap would be the paper slightly scratching the Nozzle tip.
If the paper cannot pass through the gap or does not scratch the Nozzle tip , Press "+/-" to change the gap value(increase in value results in larger gap), Press "Save" and then Press "Move" to recheck the Gap.
- Redo the printing. If the problems persist, please contact the Customer Service.
If it doesn't spin, please follow the instruction under 5-10 section on user guide to disassemble the nozzle (The user manual can be found at http://3dprinter.sindoh.com/ Downloads).

3. Check List
① Make sure that the Nozzle Assy is properly attached.
- If the Nozzle is out of position, please refer to the '5. Maintenance - 5-12 Assembling the Nozzle', reposition the Nozzle and close the Upper Cover.
- Check and Make sure that the Upper Cover is holding firmly.
② Power off the 3DWOX and move the nozzle to the leftmost position to check if the sensor is working properly.
- If the Nozzle is pushed all the way to the left wall, there will be a click sound. When the Nozzle is pulled back rightward, the sensor status changes.
- If the Nozzle is once again pushed to the left, there will be a click sound and the sensor status is switched again.
- After Checking the Nozzle Multiple times, reboot the 3DWOX to check on the EC pop-up.
※ There may be a delay due to debris, but the Nozzle will get back to its normal status after several Nozzle checks.
③ Check the Nozzle Sensor
- Check the Nozzle Sensor by fully pushing the tip of the Nozzle Assy on the left. The filler, located on the bottom of the Nozzle, should move up and down.
④ Check the Bed installation
- Incomplete installation of the Bed can cause the EC 311 Error Code. Please check the complete installation of the Bed
- If the SSID of wireless router contains any character that is not English, number or special character, you cannot find it on the 3DWOX's wireless network list.
- 3DWOX can only be found within the range of 2.4GHz. Make sure the wireless router's 2.4 GHz band is turned on in advance.
- If you access the wireless router by password, make sure it is typed in correctly. If you access the router using wireless MAC, check again to see if Mac Address is registered properly.
- Reboot the 3DWOX and try to access it again.
-Turn off the router and wait for 10 seconds to turn it back on. Once you turn it back on, check again on the 3DWOX network list.
- Locate the wireless router near the 3DWOX and then try to access. (If wireless signal is unstable, the error could occur while accessing)
- Reset wireless router with the Network Admin. (If you reset the router, its setting values will be completely erased. Make sure to work with the Network Admin).
- If the router is connected but the wireless IP cannot be found, check the router setting with the network Admin.
Move the print bed 100 scales downward in Z direction and 100 scales frontward in Y direction.
After placing the bed in proper position, turn off the device and remove the power cable.Please work with caution.
① Please insert a spring on a stud.
② As shown in the picture below, there is a hole in bottom left part of the bed where you can insert the stud.
③ Place the head of the stud facing bottom and insert it into the hole.
④ In order to secure the stud, place an E-ring to the stud while being pushed upward. Use proper tool such as Long-nose as shown in the image below
※ After assembly is finished, press the stud from the bottom 2 to 3 times to make sure that vertical movement is smooth.
Function of the Stud is to secure the bed not to move after printing is finished.
Stud’s presence or absence does not affect the quality of outputs or any other features of the device.
②Press the upward arrow
→ See if the filament comes out
→ If it does not, please proceed to page 2
2. Remove Tube from the Nozzle
Use a tool such as a LONG NOSE PLIER and pull to see if it comes out.
If it does not, proceed to the Page 4
※ Reassembling the Nozzle Tube
 Insert Tube
- Insert the tube all the way in until the tube below the black tape is unseen. (About 50mm inserted = 1.96 inches)
Insert the Snap-Ring in between the Fitting and Holder.
- Approximately 1.5mm can be additionally inserted.
3. Remove Tube from the Inner Side (Only try this if the previous steps did not work)
Pull the tube while pressing the blue Cap.
Use a toll such as a LONG NOSE PLIER to see if It comes out.
After removing the Filament, insert the Tube back in all the way (about 15mm = 0.6 inches).
3DWOX Desktop S/W
- Output quality could vary depending on how user positions a model on the bed.
Place the model in a position where the usage of support is minimized.
If the usage of support is necessary, place the model while considering the fact that parts touching the support would be low in printing quality.
Place the important part of the model facing up so its surface would be more precisely printed.
→ After slicingParts of the model attached to the support are low in printing quality.
If the part has a hole or boss that needs to be precisely printed, it is better to place the part standing up so it wouldn’t need a support.
A hole that needs to be precisely printed
A hole that needs to be precisely printed①Since this boss needs the support, it would be less precisely printed.
②If this part needs to be precisely printed more than the other part, make sure to place this part facing up so it wouldn't need a support.
- The less the usage of support, the better the printing quality.
If the model’s angle is within 60 degrees from the perpendicular, it can be printed stably with out the usage of support.
These parts (within 60 degrees) are stable without the usage of support.
Default settings are set to only create the support for parts of the output with larger than 60 degrees.
Change the value in the box If you want to set a support for parts with angle less than 60 degrees.
Even if the angle is large, it is still possible to print the model without the support if the model is short in length and has pillars on each side.
You can stably print the model of length up to 40 mm if there are supports on the each side of model.
2) "Line" infill is created in the shape of a line. The directions vary depending on the layer.
Therefore, it may look like a grid from the 3DWOX desktop.
Therefore, you can print the skirt (The Green line shown below) if you set the "Bed Adhesion Type" as "None".
<Print Only Follow Mesh Surface>
This option is used when a user only prints the surface of model. Since this option only prints the surface, it prints the model’s outer wall without infill and upper/bottom surfaces. When printing the outer wall, this option prints in minimum thickness about nozzle size.
This option is used when a model is only composed of surfaces and has empty internal space as shown in the pictures below. In case of models with no upper/bottom surfaces and has thin walls, it would be hard for normal slicer settings to discern the inside and outside. Therefore, it will create the g code as it in fills the inside of the model. In such a case, this option can be used to only print the outer wall of the model without any infill.
[3D model] Its internal space is empty and has opened entrance.
[When the option is selected] Printing the outer wall without infill, upper/bottom surfaces.
[When the option is unselected] If this option is unselected, it would be sliced as an infilled model as it is an opened type.
Also when the thickness of the outer wall is about 0.4 mm thin, it would be not possible to print it under regular settings. But when this option is activated, it would be possible to print the outer wall.
[3D model] When the thickness is 0.4mm, which is a size of the nozzle diameter
[When the option is selected] Can print the model although the outer wall is thin if this function is enabled
[When the option is unselected] Does not create the outer wall due to the thickness (too thin) because the creation of outer wall, inner wall, and infill are simultaneously executed.
However, we do not recommend this function when slicing a model that requires the solidity, because there is no infill and it prints with the least thickness, which results in printing the model with little solidity.
<Combination Mode A>
When this option is selected, it slices a combination of two or more different models with overlapped part or only one model with overlapped surfaces. As shown in pictures below, two overlapped models share the inside and create the g-code when they are sliced.
When surfaces of the model meet, they create a shared internal space and infill. As shown in pictures above, 2 or more models could be overlapped. Also this option could be used for a single model. For v.18.104.22.168, this option has been activated as default.
<Combination Mode B>
If you select this option and slice the model above, it starts slicing by integrating as the picture below and filling the internal empty space at the same time. When you need to print just the exterior of the model, this option enables you to slice in case the slicing cannot be initiated due to the entanglement or the overlap of the model.
<Close Open Faces>
This option is used to resolve an issue when slicing cannot be initiated due to a crack or a hole which are created when surfaces are not properly connected to each other. When you upload a model and slice, you may find that a part of the model disappears from time to time. Such phenomenon occurs due to invisible small cracks or holes, although there seems to be no problem externally. When designing the model, the model with defects may be created under a number of circumstances. For example, they can be created when they have been inconsistently scanned or when they have been improperly attached together.
The picture on the left above is a STL model of a rabbit and the picture on the right above is when the STL model is sliced. There seems to be no problem when uploading a model. However, if you initiate the slicing process, you can find that the part between the legs and the body disappears. A defect of the associated part’s data can be suspected.
When you enable this option and re-slice, you can find that the path, which has been fixed to a certain extent, has been created.
However, this feature can fix the defects such as small cracks only to a certain extent. The user may not be satisfied with the result. In the cases when the size of cracks and holes are too big, you need a program of which the user can manually modify the model.
The concept of this option is similar to ‘Close Open Faces’ option above but it is used in a case in which the gaps between surfaces of the model are bigger. When ‘Close Open Faces’ option is selected, slicer makes decision to fill in the gaps or little holes of the model, but when extensive stitching option is selected, slicer makes decision to connect a surface to another closest surface when there is two or more open surfaces in between the surfaces to be connected. The user may not be satisfied with the result so the usage is limited to the certain extent.
You may prevent the "gap" on the surface of the upper part of the printed object from forming by modifying the settings on "3DWOX desktop." However, be mindful of additional problems.
You may modify the settings by clicking "settings" after switching the mode to "Advanced Mode." The settings below may change depending on the printing or device conditions.
Basic > Filament > Flow Compensation : 130%
Advanced(1) > Speed > Travel Speed : 180mm/sec
Advanced(1) > Speed > Top/Bottom Speed : 20mm/sec
Advanced(2) > Retraction > Retraction Combing : No Skin
Printing quality may decrease when printing under the modified settings. Therefore, please reset the settings and print.(Setting > Reset Profile)
Aside from this bed lock function, when the print is completed, the bed is automatically lowered to the bottom and the long screw that is on the bottom of the bed holds the bed which works the same as the bed lock function so you don't have to worry about pressing the bed lock button when the print is completed.
You will be using the bed lock button when you have to reinstall the bed sheet after you cancel the print or in situations where the bed is not at the bottom of the printer.
You may remove the USB stick when the X-sign (Refer to the picture below) disappears on the screen. The bigger the size, the longer it will take for the X-sign to disappear.
[Recognizing the USB]
[USB may be removed]
There is no need to re-level the bed in between prints unless the device is substantially impacted.We recommend that you level the bed every other week if you print once or twice a day. However, there is no need to level the bed as long as the object is properly attached to the bed when printed.
The maximum speed is 200mm/s. We recommend that you print at a speed of 100mm/s or under. However, printing at a speed of 40mm/s or lower is recommended due to a noise.
