This issue may be related to either the TF card or the network connection. You can try the following steps to help identify the cause:

Test the network:
Use another phone to create a mobile hotspot and connect the printer to the hotspot. Then try sending a print again.

Check the TF card:
If the printer still only receives the print job successfully occasionally, the issue may be related to the TF card.
You can first try formatting the TF card and test again.

Replace the TF card:
If the problem continues after formatting, we recommend trying a different TF card.

If what we say is not what you mean, please tell us more details. Thanks.

And please kindly note that after binding the device, you will get 500MB of storage space to store your own models. You could go to “Me>Profile” on the APP and you will see a “+” option in the bottom left corner of the page.Then you could upload your own STL format models files to the app to print.

If you want to slice the models in the Willbuilder, you could check below tutorial video.

The "Download Failed" error is usually caused by either a network issue or a problem with the TF card.

First, please help us check your network connection by sending us a photo or screenshot of the WiFi Info screen. This will allow us to verify whether the printer is connected properly and identify any network-related issues.

If the network appears to be normal, we can arrange a replacement TF card for you.

We look forward to your reply.

Hey my 3D prints have spacing some times any tips how to help that stop

Hi!

If your prints are showing gaps or inconsistent spacing, there are a few common things you can check:

To help us identify the exact cause, could you please send us:

Once we have this information, we'll be happy to help you troubleshoot further.

We are continuously improving our AI-generated models, so it is normal for some generated models to have minor imperfections or printing defects.

To help determine whether the issue is related to the model or the printer itself, we recommend printing one of the built-in models available in the app. This will allow us to verify whether the printer is functioning normally.

If the built-in model prints successfully, the issue is likely related to the generated model. If you experience the same problem with the built-in model, please let us know, and we'll be happy to continue troubleshooting with you.

Thank you for your patience and support.

If you encounter difficulty removing the tube, you can carefully cut the tube as demonstrated here:

This type of issue is usually related to the Wi-Fi connection or network environment.

We recommend that you send a screenshot of the WiFi Info page to our support email and provide a detailed description of the problem you are experiencing. This information will help our technical team investigate the issue more effectively.

After reviewing the information, our support team may ask for your shipping address if any replacement parts or further after-sales service are required.

To resolve the layer shift issue, please download the file provided below, copy it to your TF card, and then print the file on your printer:

https://drive.google.com/open?id=1j2AYDr77ar_o_WF_8EzdHx3YcWPQ42SZ&usp=drive_fs

Printing this file will help correct the issue and restore stable printing performance.

After the print is completed, please test your original model again and let us know whether the problem has been resolved.

If you continue to experience layer shifting, please feel free to contact us for further assistance.

Download 3D Models: You can find a wide variety of 3D models to print from the following websites:

Extract the Model Files: Once you find a model you like, download the file to your computer. These files are typically compressed in ZIP format. To access the model, you will need to unzip the file, which will reveal the STL file. The STL file is the standard format used for 3D printing.

Prepare the Model for Printing: The next step is to prepare the model for printing, which involves slicing the STL file. This process converts the model into layers that your 3D printer can understand. Depending on your setup, you can do this using the following options:

Feel free to reach out if you have any questions or need further assistance with your 3D printing projects.

You can find it in wiibuilder.

Then you can get the configuration file which also include Tina 2 plus in below link:

The download link can be found at the bottom of the document. You may copy the files to your TF card to begin printing. If a computer is not available, please don’t worry—the packaging includes an adapter that allows you to transfer the files to the TF card using your phone, so you can continue with printing smoothly and without any difficulty.

And below are some modeling software:

After connecting the printer with the APP and the wifi, you could go to “Me>Profile” on the APP and you will see a “+” option in the bottom left corner of the page.Then you could upload your own STL format models files to the app and to print it.
