Generally, when a user of a 3D printer prints an object using the 3D printer, an acquired 3D printing model file is generated by various modeling software, or a control instruction file of the object is directly acquired. The user can only print in accordance with the printing mode of the original model, and cannot set the printing initial position autonomously. However, in some application scenarios, problems may be encountered, for example, a user wants to attach a model to a designated position of another object, or a user wants to print a generated object at a designated position, or a user wants to print by fully utilizing the space of a printing area. However, since the user does not know the form and specific initial position of the model in the control instruction file or the model file, if the user sets the model based on experience, the error between the initial position set by the user and the actual initial position of the model is easily caused by the dependence of the 3D model on the base. In which case the user needs to make several attempts to obtain the desired print result, or cannot obtain the desired print result at all. Therefore, it is desirable to provide a method for flexibly setting an initial printing position for a user to improve the usability of a 3D printer.

As shown in fig. 3, the method includes steps S110 to S160. The specific realization principle of each step is as follows:
s110, responding to the movement control operation, and sending a movement control instruction to the printing module; the movement control instructions are for moving the print nozzle to a reference print position determined by the movement control instructions.
In some embodiments, the user performs a movement control operation through the user graphical control interface of the controller 120, for example, clicking up, down, left, right, etc. directional buttons of the user graphical control interface.
In some embodiments, the user performs movement control operations through a directional control handle or directional control terminal communicatively coupled to the controller 120.
The movement control instruction is an instruction for controlling the operation of each axis in the printing module, and includes but is not limited to an instruction for controlling the movement direction and distance of the axis. In one non-limiting example, the user performs the movement control operation through the user graphical control interface of the controller 120, for example, clicking the up, down, left, right, etc. directional buttons of the user graphical control interface performs the movement control operation. The controller responds to the movement control operation for sending a movement control instruction to the printing module, the printing module responds to the movement control instruction, the motor of each shaft operates according to the control parameter of the movement control instruction, the printing nozzle reaches the position selected by a user along with the operation of each shaft, and the position is a reference printing position.
And S120, acquiring the current coordinate parameter of the printing module as a reference coordinate after the printing nozzle moves to the reference printing position.
In some embodiments, a controller, such as a host computer, determines the movement control instruction in response to a jog operation directed to a direction control of the control interface, and issues the movement control instruction to the print module; the movement control instructions are for moving the print nozzle to the reference print position determined by the movement instructions; and after the printing nozzle moves to the reference printing position, responding to the click operation of a recording control aiming at the control interface, and acquiring the current coordinate value of the printing module as the reference coordinate.
In one specific non-limiting example, the controller is a host computer and the print module is a three-axis print module. The control interface of the computer displays a directional control, and a recording space. And a user clicks the upper, lower, left, right and other azimuth buttons of the direction control through touch operation or mouse operation on the control interface to perform movement control operation, the upper computer responds to the movement control operation of the user to generate a movement control instruction corresponding to the movement control operation, and the movement control instruction is sent to the triaxial module. And moving the three-axis module to align the printing head nozzle to the position specified by the user in the three-dimensional working area of the three-axis module. And a user clicks the recording control through touch operation or mouse operation on the upper computer control interface, the upper computer responds to the operation aiming at the recording space, and the coordinate parameters of all the axes of the current triaxial module are obtained according to the encoder values of the triaxial module and serve as the reference coordinates. For example, the coordinate parameter X of the X-axisrefThe coordinate parameter of the Y axis is YrefThe coordinate parameter of the Z axis is ZrefReference coordinate cref＝(xref,yref,zref)。
S130, acquiring initial coordinates of the model in the source printing control instruction file.
The printing control instruction file includes, but is not limited to, a G code file, and the G code file is a file composed of a printing control instruction set generated by slicing a three-dimensional 3D model by using slicing software. The source printing control instruction file is an existing G code file acquired by a user.
In one non-limiting example, the controller, such as a host computer, reads the existing G-code file loaded by the user, and looks up the initial coordinate parameters of the model in the file. In some embodiments, the minimum Z-axis value in the G-code file is found as the Z-axis parameter of the initial coordinates, and in some embodiments the first instruction in the G-code file generally defines the model base coordinates, e.g., G1Z 0.30, and this value is used as the Z-axis parameter of the initial coordinates.
In some embodiments, an initial plane is determined from a minimum Z-axis value of the model; acquiring the boundary of the model in the initial plane; and determining the initial coordinate according to the coordinate value of the boundary. It can be understood that the initial plane is determined by the minimum Z-axis value of the model, and the initial coordinates are determined according to the coordinate values of the boundary, the printing start point starts from the bottom surface, and the printing success rate is improved due to the dependence of 3D printing on the bottom surface.
Specifically, after the upper computer determines the minimum Z-axis value, the initial plane is determined according to the value; and traversing the G file, searching the coordinate values of the points of the initial plane, and obtaining the boundary of the model on the initial plane according to the coordinate values of the points of the initial plane, namely the intersection line of the model and the initial plane. The initial coordinates may be determined by finding the geometric center or center of gravity of the boundary.
In one non-limiting example, a first centerline of maxima and minima of the boundary on the X-axis is taken; acquiring a second central line of the maximum value and the minimum value of the boundary on the Y axis; and taking the coordinates of the intersection point of the first middle line and the second middle line as the initial coordinates. As shown in fig. 4, the maximum value X of the boundary on the X axis is obtained2And the minimum value x1First central line of(ii) a Obtaining the maximum value Y of the boundary on the Y axis2And the minimum value y1A second centerline of (a); taking the coordinates of the intersection point a of the first and second central lines as the initial coordinates cini＝(xini,yini,zini)。
In another non-limiting example, a mean value of coordinates of each point of the boundary is obtained, for example, a mean value of coordinates of each sampling point of the boundary is obtained, and a sampling mode can be determined according to actual conditions; and taking the average value as the initial coordinate. For example, the coordinates of each sample point of the boundary are (x)i,yi) The initial coordinates
Wherein N is an integer greater than or equal to 1 and represents the number of sample points of the boundary.
S140 calculates an offset amount of the reference coordinate from the initial coordinate. The reference coordinate and the initial coordinate are coordinates in the same coordinate space; the offset coffsetIs the vector difference c of the reference coordinate and the initial coordinateoffset＝cini-cref。
And S150, generating a target printing control instruction file according to the offset and the source printing control instruction file.
In a non-limiting manner, a controller, such as a host computer, adds all coordinate parameters in the source print control command file to an offset to obtain an updated control command file, i.e., a target print control command file. In one non-limiting example, generating a target print control instruction file based on the offset and the source print control instruction file comprises: extracting a source coordinate set in a source printing control instruction file; without limitation, the correspondence of each coordinate in the source coordinate set to the control instruction is marked while the source coordinate set is extracted. Obtaining a target coordinate set according to the coordinate values in the source coordinate set and the offset; and controlling the corresponding relation between the instruction set and the source coordinate set according to the source coordinate. Generating a target control instruction set from the source coordinate control instruction set and the target coordinate set; and generating a target printing control instruction file according to the target control instruction set.
And S160, sending a printing control instruction to the printing module, wherein the printing control instruction is used for controlling the printing module to print the target object according to the target printing control instruction file.
In one non-limiting example, the controller, such as the host computer, sends the control commands in the target print control command file to the print module, and the print module prints the target object, i.e., the specific model, starting from the reference coordinates according to the control commands.
In another non-limiting example, the host computer sends the target print control instruction file to the print module. And the upper computer responds to the operation of the user and sends a file execution instruction to the printing module, and the printing module starts to read the G code control instruction set subjected to offset processing in a line and directly prints the 3D model at the position determined by the reference coordinates of the 3D model.
It can be understood that, through obtaining the offset between benchmark coordinate and the initial coordinate, and print control command file according to this offset correction source, make the 3D printer print the position at the benchmark, made things convenient for the common user to select and begin to print the position, can convenient and fast in the three-dimensional space work area of triaxial module in arbitrary a within range, height position promptly, the setting of printing the position in the uncertain space of horizontal position, carry out the accurate positioning according to user's consideration angle, thereby the ease of use of system has been improved.
It is understood that the printing control method provided by the embodiment of the present application is also applicable to positioning setting of a laser engraving and a numerical control (CNC) machine.
On the basis of the embodiment of the method of print control shown in fig. 3 described above, in step S110, a movement control instruction is issued to the print module in response to a movement control operation; the movement control command is used to move the printing nozzle to the position before the reference printing position determined by the movement control command, as shown in fig. 5, and further includes step S101:
s101, responding to a zero returning operation, and sending a zero returning instruction to the printing module; and the zero returning instruction is used for returning the printing module to zero.
The zero returning means that all shafts of the printing module are returned to an absolute zero position, and the current value of an encoder of each shaft at the zero position is 0. For example, the X, Y and Z axes of the three-axis module are brought back to the zero position.
In a non-limiting example, when a user selects a serial number point corresponding to the printing module in a serial selection space on a control machine, such as an upper computer, the user control interface clicks an initialization button control to initialize; and the upper computer sends a zero returning instruction to the printing module according to the initialization operation, and after the zero returning is successful, a user can perform inching operation on the direction control of the user control interface and read the current coordinate values of all axes of the three-axis module through the user control interface. The zero-returning operation of the printing module can be initialization of each axis coordinate value, so that errors in the position of the initialized coordinate when the printing module is powered on can be avoided, and it should be understood that the sequence number of each step in the above embodiment does not mean the sequence of execution, and the execution sequence of each process should be determined by the function and the internal logic thereof, and should not constitute any limitation to the implementation process of the embodiment of the present application.
