The control programs of the CNC 10 and the channel bending machine 20 are integrated into one, and the integrated control program 30 operates in the CNC mode and the channel bending mode according to the mode selection.

In the CNC mode, the CNC 10 operates as follows.

Curiaboard is a microcontroller and is also referred to as Zenith.

A CNC controller 120 operating in the curator board, and a control program operating in the computer 110.

The computer 110 parses the G code file and displays the coordinate movement, and the CNC controller 120 controls the motor drive.

Software flow chart and class diagram

The computer 110 parses the G code file, calculates the coordinate shift, and transmits the motor feed amount. The CNC controller 120 drives the motor.

Software function

The computer 110 opens the G code file, calculates the motor feed amount according to the coordinates, and transmits the motor feed amount to the CNC controller 120 so that the CNC controller 120 drives the step motor according to the motor feed amount.

How to use the control program

Commands include init, open, run, simul, wait, and close. You can control the program by typing the command and pressing the enter or spacebar.

init sets the serial port and enters the variables to set the coordinates. Press the change button to set the current coordinates. open opens and loads the G code file.

run transmits the motor drive profile generated based on the G code file loaded with the control program to the CNC controller 120 to drive the motor through the motor drive circuit.

simul runs a virtual operation based on the loaded G code file. wait stops the motor drive. close closes the loaded G code file.

For example, you can use init to set the serial port and current coordinates, open the G code file using open, and run control based on the G code file using run or simul. In addition, it is possible to return to the operation control by inputting the wait in the operation and pausing the operation, and then inputting the run again. If you want to stop the motor urgently during operation control, you can interrupt the power supply or issue a wait command to the control program.

FashLed has a curriculum program.

In the upper right corner, there are coordinates movement, G function opening, execution, stop, origin setting and Z axis zero point setting that can control CNC.

If an emergency stop is required, press the stop.

Hardware Configuration

Install the program on the CNC controller (120) and set the communication port.

Combine the CNC controller (120) with the GRBL board and connect and test the bipolar stepper motor.

int Run_Proc (struct GcodeData * gd, struct Coord * xyz, struct MODE * Mode, HWND hWnd, struct Ui * ui, struct STR * OprStr, struct STR * pStr);

The computer 110 opens a G code file, sets the current coordinates by coordinate loading, acceleration, constant velocity, deceleration, and transmits a motor movement command during acceleration.

Interpret the command (cmdpro.c)

open, close, init, debug, run, wait, simul Compare strings and set mode. The modes are open mode, closed mode, initialization mode, run mode, weight mode, and simulation mode. The open mode is to open the file, the close mode to close the file, the initial mode to set the coordinates and set the communication port, the run mode to open the G code, calculate the movement coordinate value and send the motor movement command, Open the code file and move to the move coordinates value.

G code parsing (gpas.cpp)

Open G code file and read G code value, N value, X, Y, Z value by string comparison.

Set the target coordinates according to the read value.

Transfer of feed (trcood.cpp)

The feed amount transmission sets the coordinate range and sets the target coordinates.

Calculates the total step, calculates the time constant, calculates the acceleration step, and instructs the start of movement.

The total step is calculated by dividing the movement amount by the pulse movement amount.

The time constant is equal to co_acc = 2./400/(co-> F/36)*sqrt(N)*Freq/Scale;

The acceleration step

i = 0;

vax = 0;

ax = co-> lx / co-> l;

if (vx> 0)

{

do

{

i ++;

vax = sqrt (2 * co_acc * ax / dlinv * i);

} while (vax <vx);

}

axs = i;

co-> ax_step = axs;

.

Full motion control (ui.cpp)

The run operation operates by switching between the arrival state, the weight state, the G code parsing state, the acceleration state, the constant velocity state, and the deceleration state.

The operation sequence is G code parsing state -> acceleration state -> constant velocity state -> deceleration state -> arrival state.

It is determined whether or not there is an arrival over an acceleration state, a constant speed state, and a deceleration state.

Communication port settings (com.cpp)

If the communication handle is OK, the format message is executed.

Configure it using communication port function.

Machine image output (outline.cpp)

The machine image can be used to initialize a point list, open an outline, open a line, initialize a line, insert a line, delete a line, obtain a line index, X coordinate pixels, Y coordinate pixels, , Obtaining milling coordinates, obtaining a milling table, obtaining a drill, updating a table, and updating a drill.

The point list initialization initializes the point value, the outline opening is the milling coordinate, the milling table, the drill is opened, the line opening is opened, the line initialization initializes the line structure, The line index is obtained by obtaining the final line index, the X coordinate pixel is converted into the pixel coordinate, the Y coordinate pixel is converted into the Y coordinate pixel coordinate, and the window area drawing is performed in the set window area And the line drawing takes the line, the window area update acquires the window area, the current point represents the current coordinate, the milling coordinates get the coordinates of the milling image, and the milling table gets the coordinates of the milling table image Acquiring the drill obtains the coordinates of the drill image, and updating the table moves the table according to the coordinate movement And the drill update updates the drill image according to the coordinate shift.

Main action (cncwin.cpp)

The main operation controls the operation status according to the keyboard and mouse input.

Keyboard input sets the mode by inputting a character string input by the keyboard.

Mouse input processes the mouse input to update the window area and handle button input.

The generated message creates the button, and the command message controls the operation according to the button value and the keyboard input.

The timer message operates the pass timer and the on-timer.

The pass timer calculates the delta time as a time value, and the on-timer outputs various parameters.

The character message processes the keyboard input and switches modes.

Processes the mouse move message to update the current pixel point, and processes the mouse wheel message to update the window area.

The paint message creates a memory dictation and draws a memory dictation corresponding to the window.

The destroying message returns memory.

String output (prtstr.cpp)

String output consists of string initialization, string insertion, string output, integer string conversion, and double string conversion.

The string initialization initializes the string structure, the string insertion inserts the string into the string queue, the string output outputs the string inserted into the string queue, the integer string conversion converts the integer to the string, and the double string conversion Converts a double to a string.

In the channel bending machine mode, the channel bending machine 20 reads a CAD file, generates a G code for instructing the operation of each motor of the channel bending machine 20 corresponding to the line path, Each motor is controlled.

The channel bending machine 20 calculates the degree of bending of the line path and generates a G code that controls the moving distance of each motor proportional to the degree of bending. The channel bander 20 controls each motor based on the generated G code.
