[0053] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0054] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0055] Existing 3D printer tutorials typically consist of a print manual, separate printable images and text, or a separate print instruction video. Users often need to switch back and forth between watching the tutorial and operating the printer to complete their first print, negatively impacting the user experience. Therefore, this application provides a print instruction method for the client side that eliminates the need to switch between viewing the tutorial and operating the printer, thus significantly improving the user experience. Figure 1 As shown, this application provides a printing guidance method applied to a client. The client can be a mobile terminal or a fixed terminal. Mobile terminals include mobile phones, tablets, wearable devices, etc., while fixed terminals can include computers and other terminals. The printing guidance method specifically includes the following steps:

[0056] 101. Obtain print instruction request.

[0057] In this embodiment, the client can obtain a print guidance request. A printing application (APP) can be installed on the client, allowing the client to communicate directly with the printer, such as via Bluetooth or Wi-Fi (mobile hotspot), or indirectly with the printer, such as via a cloud server, to control the printer for leveling or printing. This print guidance request is a request for print guidance information; the client can receive print guidance requests triggered by the user on the printing application.

[0058] 102. Based on the print guidance request, display print guidance information to guide the user to operate a printer other than the client.

[0059] Upon receiving a print guidance request, the client can display print guidance information to guide the user in operating the printer (other than the client itself). It is understood that the client displaying the print guidance information and the printer are on different terminal devices. During print guidance, the user can view the information on the client and simultaneously operate the printer. User operations on the printer can include pre-printing preparations such as leveling and adding consumables, or triggering the printer to start printing; the specifics are not limited here. It is understood that the print guidance information is primarily used to guide users who are unfamiliar with operating the printer for the first time. The client does not necessarily need to display print guidance information every time it opens the printing application; displaying it only after receiving a print guidance request ensures timely guidance and helps the user operate the printer.

[0060] The printing guidance information displayed on the client can be either a printing guidance document or a printing guidance video; the specific type is not limited here. That is, it can display either a printing guidance document or a printing guidance video to guide the user in operating the printer outside the client. The printing guidance information includes leveling instructions or instructions for adding consumables, etc. Users can also select the printing guidance information they want to view on the client and operate the printer based on the guidance information.

[0061] In one possible implementation, after a user operates the printer, the printer can send the corresponding operation result back to the client. During the user's operation of the printer based on the printing guidance information, the client can receive and display the operation result fed back by the printer. It is understood that printing guidance can be provided through a cloud platform, and the cloud platform's client can establish a communication connection with the printer. This communication connection can be based on a message transmission protocol, such as MQTT or AMQP, which is not limited here. After each user operates the printer, the printer will send the corresponding operation result back to the client through the communication connection, and the client can display the operation result to the user.

[0062] 103. If a print start command is received, send print information to the printer.

[0063] When the client receives a print start command, it can send print information to the printer to initiate printing of the model. Understandably, the client can have a virtual touch location (button) for starting print, which the user can touch to initiate the print start command. The print information sent by the client to the printer includes the model file to be used, allowing the printer to print based on that file. Understandably, the user can select the model file on the client, or the client can use a default model file; the specific choice is not limited here. The model file can be a print file prepared for printer slicing, including all the content required for printing.

[0064] When a client sends print information to a printer, it can send the information directly to the printer to start printing, or it can send the print information to a cloud server first, and then the cloud server will transmit the print information to the printer to start printing indirectly. The specific method is not limited here.

[0065] As can be seen, in this application, the client obtains a print guidance request; based on the print guidance request, it displays print guidance information to guide the user in operating the printer outside the client; if a print start command is received, it sends print information to the printer to start printing the model. Print guidance information can guide the user to operate the printer outside the client for printing. The user can operate the printer while viewing the print guidance information on the client, eliminating the need to switch back and forth between viewing the print guidance information and operating the printer, thus improving the user experience.

[0066] The following section will further describe the printing guidance process using the client's interaction process, such as... Figure 2 As shown, the specific steps are as follows:

[0067] 201. Obtain the connection request to the printer.

[0068] In this embodiment, the client needs to establish a communication connection with the printer, and the client can obtain a connection request to connect to the printer. Specifically, the client can automatically obtain the connection request when starting the printing program, or the user can trigger the connection request on the client; the specific method is not limited here.

[0069] A connection request to the printer can be generated automatically by the program or by the user operating the client.

[0070] In one feasible approach, when a user starts the printing program on the client, a prompt message for connecting to the printer will be displayed on the client, asking the user whether a printer connection is required. This prompt message can be a pop-up window or text; the specific type is not limited here. After seeing the prompt message, the user can determine whether a communication connection has already been established with the printer. If a communication connection has been established, the prompt message can be ignored; if not, a connection request to connect to the printer can be triggered on the client. It is understood that the prompt message displayed on the client includes touch buttons for skipping the connection and initiating the connection. The user can trigger the printer connection request on the client by touching the touch button to initiate the connection.

[0071] 202. Send a communication establishment request to the printer to establish a communication connection with the printer.

[0072] After receiving a connection request from the printer, the client can send a communication establishment request to the printer to establish a communication connection. Understandably, the client can send a message transmission protocol to the printer and establish a communication connection by receiving a response protocol from the printer. In other implementations, the client can first connect to the printer wirelessly via Bluetooth or Wi-Fi generated by the printer. After the client sends a communication establishment request to the printer, the printer receives the request, which includes network information. Based on this network information, the printer connects to a wireless signal with network access, such as Wi-Fi, to establish a communication connection between the printer and the client via the cloud platform.

[0073] 203. Obtain print instructions request.

[0074] The client can determine whether it needs to enter the print guidance by receiving a print guidance request. This print guidance request can be triggered by the user on the client or by the client when the printing program is opened; the specific trigger is not limited here.

[0075] One approach involves the user triggering a print request on the client side. After opening the printing application, the client can display a prompt to guide the user through the printing process, asking if they wish to proceed. This prompt can include options to enter the printing guide and skip it, allowing the user to decide whether to proceed and select the appropriate touch location. In one feasible implementation, the prompt can exist as a floating window on the client side. If the user encounters unclear operations while using the printing program, they can tap the floating window to expand and display the printing guide, then follow the prompt by touching the corresponding touch location.

[0076] When a client opens a printing program, it triggers a print guidance request by obtaining the program's start command. For example, if a user opens the printing program on the client, the client confirms that the program is being opened for the first time based on the start command, and then uses that start command as the print guidance request. In other words, the client identifies the printing program when it is opened, and if it recognizes that the printing program is being opened for the first time, it automatically uses that start command as the print guidance request.

[0077] After receiving the print instruction request, the client begins displaying the print instruction information. This information includes leveling instructions, filament addition instructions, and model selection instructions, such as... Figure 3As shown, generally, pre-printing preparation guidance information can be displayed first, including leveling and filament addition guidance. Then, printing start guidance information, such as model selection guidance, can be displayed. It's understandable that the client-side includes an option to select and display information. For example, a touch-sensitive button could be provided in the client to display the next printing guidance information; users could then touch this button to access the next guidance. Alternatively, multiple printing guidance information could be set in a list, allowing users to select the desired guidance.

[0078] Users can view printing instructions on the client and simultaneously operate the printer. The printer then sends the corresponding operation results back to the client, as shown in steps 204 to 213 below:

[0079] 204. Display leveling guidance information.

[0080] The client can display leveling instructions to guide users in leveling the printer. These instructions can be a video tutorial, allowing users to complete the printer leveling process by watching the video. After watching the instructions, users can either trigger a printer leveling request through the client or directly control the printer to perform the leveling; the specific method is not limited here.

[0081] 205. Receive printer leveling requests triggered by users.

[0082] After watching the leveling guide video, users can trigger a printer leveling request on the client based on the video. This is achieved by having a touch button on the client to trigger the leveling process. Users can touch this button while watching the guide video, and the client detects this touch button to receive the user-triggered printer leveling request. This touch button can be a virtual button on the client's display screen.

[0083] 206. In response to a leveling request triggered by the user based on the leveling guidance information, send a leveling command to the printer.

[0084] After receiving a user-triggered printer leveling request, the client can send a leveling command to the printer. Upon receiving the leveling command, the printer initiates the leveling process and sends the leveling result back to the client. This result can be either a successful leveling result or a leveling failure result. Understandably, if the printer fails to level successfully within a certain timeframe after initiating the leveling process, it can directly return a leveling failure result.

[0085] 207. Receive and display the leveling information sent by the printer.

[0086] The client can receive and display the leveling results sent by the printer. Users can then determine whether to proceed to the next step or continue with the leveling operation by viewing the results. If the leveling result is a failure, the user can re-trigger the leveling request through the client or directly operate the printer to perform the leveling. It's understood that errors 205 to 207 may not exist; the user can view the leveling instructions, directly operate the printer to perform the leveling, and manually judge the leveling result.

[0087] 208. Display instructions on adding consumables to guide the user in placing consumables into the printer's feed hopper.

[0088] The client can display consumable addition guidance information to guide the user in placing consumables into the printer's feed tray. This guidance information can be a consumable addition instruction video, which the user can watch before placing the consumables into the printer's feed tray to complete the consumable addition operation. It is understood that the client can display the consumable addition guidance information after receiving a successful leveling result from the printer, or it can be displayed after the user triggers a touch button on the client to proceed to the next step; the specific method is not limited here.

[0089] 209. Receive and display the consumable placement results sent by the printer.

[0090] The printer continuously monitors the filament placement information in the feed tray and sends this information to the client. Users can access this information via the client to determine if additional filament is needed. After placing filament in the feed tray, the printer sends a placement result to the client, indicating whether filament is in the tray and the quantity. The client receives and displays this result to help users confirm successful placement and determine if more filament is required. It's understandable that error code 209 might not exist.

[0091] 210. Display the list of model files.

[0092] After printing preparation is complete, a model selection guide can be displayed to instruct the user to choose a model file for printing. This guide includes a list of model files, containing multiple model files (Model A, Model B, Model C), which can be displayed on the client side. It's understood that the client can obtain the model file list from a cloud server or pre-store it on the client; the specific method is not limited here.

[0093] 211. Receive the print start command triggered by the user from the target model file selected in the model file list.

[0094] After displaying the model file list on the client, the user can select a target model file from the list. The client can then receive the print start command triggered by the selected target model file. Understandably, the client will also display a touch button to start printing while showing the model file list. After selecting a target model file, the user can touch this button to generate the corresponding print start command.

[0095] 212. Send the print command containing the target model file to the printer.

[0096] After receiving a print initiation command triggered by the user, the client can send a print command containing the target model file to the printer to start printing based on that target model file. It can be understood that the client can send the print command directly to the printer, or it can first send the print command to the cloud server, and then the cloud server sends it to the printer. In other words, sending print information to the printer includes sending a print command containing the target model file to the printer.

[0097] 213. Receive and display the printing operation results sent by the printer.

[0098] After starting printing, the printer can provide real-time feedback on the printing operation results to the client. The client can receive and display the printing operation results sent by the printer. The printing operation results can include whether the printing was successful or failed, and can also include the printing progress. It's understandable that the printer can directly provide printing operation results to the client, or it can send the printing operation results to a cloud server, and then the cloud service will send them to the client.

[0099] As can be seen, in this embodiment of the application, the user can view the printing guidance information through the client and operate the printer outside the client at the same time. The corresponding operation results can be displayed on the client. By viewing the operation results on the client, the user can operate the printer more conveniently.

[0105] The client also includes a connection unit, which is used to obtain a connection request to connect to the printer and send a communication establishment request to the printer based on the connection request, so as to establish a communication connection with the printer.

[0106] Specifically, the display unit 402 is used to display a printing guidance document or a printing guidance video based on the printing guidance request, so as to guide the user to operate a printer other than the client.

[0107] The display unit 402 is further configured to: display leveling guidance information; send a leveling instruction to the printer in response to a leveling request triggered by the user based on the leveling guidance information; and receive and display the leveling result fed back by the printer.
