Frequently Asked Questions

Error Code
※ EC 302 and 306 both occur in the same Nozzle area. (Thus, these two share a solution.)
- EC 302 : This error occurs when the temperature doesn't rise above 10℃ within 30 s from the initiation of heater.
- EC 306 : This error occurs when the difference between the targeting temperature and device temperature is over 20℃ and continues more than 5 mins.

1. Turn off the device, open the nozzle cover, and detach the connector (connected to the red harness) on the right.
Refer to the Page 130 of the User Manual.
(Go to Chapter 5 Maintenance → 4.4 Exchanging Nozzle → #3, #4)

2. Check the interior of the connector of the nozzle and the main board to see if there are any impurities.

3. If no impurities are found, reattach the connector.
Push the red harness towards the direction of the connector one to two times to check
whether the connector is properly connected (Do not pull it out)

4. Turn the device back on and check if EC-306 or another Error Code still occurs.

1. Phenomenon
Nozzle Sensor status does not change after Booting 3DWOX.

2. Causes
  1) Faulty Nozzle Sensor
  2) Incomplete installation of the Bed

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

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).
Usual warping occurs when the excreted Filament starts to cool down.
The newest Filament that has been excreted on the highest layer has a higher chance of warp, which is the reason why the corners of the 3D models warp.
ABS Material has more tendency to warp than the PLA material.

Warping Improvement Instructions:

1. Operate 3DWOX at a fairly warm temperature (61 ~ 84 ℉)
 - Cold weathers can cause warp in the printed models.

2. Close all the doors while printing.
 - Opening top and front doors can affect the printed model

3. In cases where the shape of the 3D Model has a Countergradient or Bridge shaped bottom, please turn off the fan.
 - In order to change the Fan settings, change the mode to advanced mode.
 - Go to Settings - Advanced (2) - Cool - Minimum/Maximum Fan Speed and change the values.
 - Default value for PLA is 50% and ABS is 3%

4. Change the Infill rate of the model.
 1) Change to Advanced Mode(Mode - Advanced Mode)
 2) Change the Infill Rate (Settings - Basic - Fill - Fill Density)
  - Default value for PLA is 15% and ABS is 10%

5. Go through the manual Leveling.
 - Please refer to the [FAQs] - [Trouble Shooting] - [Manual Bed Leveling Method] tab.

6. For large sized models with large bottom surface, please print with PLA.
 - ABS has a tendency to contract easily.

7. Please print the model in the middle of the bed.
 - Corners of the bed sheet (especially close to the front door) are easily affected by the outside temperature, causing warp.

8. Use as least time as possible for pausing.
 - During the pause, the inner temperature of the 3DWOX decreases, which can affect the warping of the 3D model.
※※ Before the execution, please go through "Auto Bed Leveling".
(Refer to the following link: http://3dprinter.sindoh.com/ VideoTutorial , "BedLeveling")

1. Get a business card (or a hard surfaced paper)
2. On the printer display, go to Setting - Z offset
 - Move The nozzle and the bed will move around and eventually the nozzle will position on the middle of the bed

3. Pull the bed until the Sindoh logo is covered

4. Push the business card in between the nozzle and the bed and move it around. If you feel a little bit of scratching the bed level is complete.

※ Caution. There is a spring system under the bed. If you press the bed down while moving the business card around, the bed will move downward, causing an incorrect leveling of the bed.
 - If you cant move or cant fit the business card in between the nozzle and the bed = Increase the Z offset value and press move
 - If you cant feel any scratching on the business card = Decrease the Z offset value and press move
 - On the appropriate Z offset value, press save

5. Push the bed back and manually move the nozzle to the left end.
Same way as Step 4, push the business card in between the nozzle and the bed and calibrate until the appropriate height.

During calibration, do not use the Z offset menu, but instead, turn the knob.
- If you cant move or cant fit the business card in between the nozzle and the bed = Turn the knob clockwise
- If you cant feel any scratching on the business card = Turn the knob counterclockwise

※ Rotating the knob by one revolution changes the height by 0.8mm.
Rotating the knob by one edge changes the height by 0.1mm
※ Please rotate ONLY the Left knob!

6. After the left side calibration is complete, move the nozzle to the right side.
Repeat step 5.

7. Usual calibration ends after step 6.
Users can print a small object to see whether the bed leveling calibration is appropriate enough for printing.

Bottom surface is wiggly → Decreases Z Offset.
* Example of printed work with Z offset of 1mm higher than the appropriate value

Bottom surface is pushed → Increase Z Offset.
* Example of printed work with Z offset 0.5mm less than the appropriate value

Appropriate Z Offset

Go through Setting - Next - Test Print - Line Test (Approximately 25 min)

※ The bed leveling becomes very sensitive when outputs are printed without a raft.
Unless under certain circumstance, please use the Raft On option when printing.
  * If Advanced Mode, Check the Settings.
  * Advanced Mode : Settings - Basic - Support - Bed Adhesion Type - Raft

- 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 slicing
    Parts 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 printed
    ①Since 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.

1) "Grid" infill is created in the shape of a grid.
(layer 120)
(layer 121)

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.
(layer 120)
(layer 121)

"Skirt" is a paramater that operates only when "Bed Adhesion Type" is set as "None".

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., 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.

On the same model as above, it creates the G-Code by extracting the exterior and filling the internal space.

<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.

It is difficult to find the models with defect on the current slicing program. You must check on the program that professionally deals with the model. The picture on the left is what appears when the same model is loaded on the program called “Meshmixer” which has been developed by Autodesk. This program simply analyzes the surface of the model and displays it on the screen. On the left picture, you can find the blue lines on the body and the legs of the rabbit. Namely, the model does not consist of a single model. It is a model that is created by attaching the legs and the body. The blue line is created where the legs and the body are attached. In case the size of a crack surpasses a certain size, the slicer cannot create a path of a nozzle and delete it on the screen. This feature attaches these cracks so that the model can be sliced.

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.

<Extensive Stitching>

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.

A gap can form in case the upper surface area of the printed object is wide and multiple movements take place inside the model, leading to filament loss.
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)
Skin Outline reinforces the outline of skin area so as to help in building the top and infill together on 1 layer.

For example of Venus shape, the outline is reinforced between the infill and top of it. For FDM, there can be a gap between the boundary of leg line and top plane of Venus shape. With the skin outline, the gap of boundary line can be improved.
The following image will help understanding.

[Before applying skin outline]
The outline is not reinforced between the infill and top.

[After applying skin outline]
The outline is reinforced between the infill and top.

* Layer Color : Select colors to print by layers.

◈ For DP200/DP102 and DP201/DP202

- Pause the printing on the desired layer. Unload the cartridge, replace it, and continue printing.

◈ For 2X and 2X DP303

01. The Layer Color is a function to specify different cartridges for different layers. Move the left-side slider to show slider positioned layer and the layer number. Position the slider at cartridge change desired layer and press the [Add] button in the bottom.

02. Then, another tab is created to replace cartridges by layer. Move the slider, and press the [Add] button to add more Layer Color.

▶ 0th to 69th layers are printed by cartridge 1 and 69th to 230th layers are printed by cartridge 2.
▶ If the boundary cross-sectional area of the layer color is small, increase the infill density of the internal filament for ensuring durability.

For the cleaning case, the printer will notify you on when to clean the case, follow instructions. For the nozzle in times of changing material or changing color of filament, under settings initiate nozzle cleaning.
The purpose of the bed lock is to easily reinstall the bed sheet on to the bed. When you are reinstalling the bed sheet, if the bed lock button is enabled, it will hold the bed so that the bed won't be pushed back when you slide the bed sheet on to the bed.

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.

[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.
