4. Candle Software

Candle is a GUI application for GRBL-based CNC-machines with G-Code visualizer. Candle is an open-source software suitable for CNC machine tool processing. It supports G code file processing and visual display.

Supported functions:

(1) Controlling GRBL-based CNC-machine via console commands, buttons on form, numpad. (2) Monitoring CNC-machine state. (3) Load, edit, save and send G-code files to CNC-machine. (4) Visualizing G-code files.

4.1 States

Work coordinates:

Represents current X, Y & Z local coordinates of the CNC.

Machine coordinates:

Represents current X, Y & Z absolute machine coordinates.

One of following CNC status:

• Idle - waiting for a G-code command Running - running a G-code command Home - homing cycle is executing
• Check - G-code command check mode is turned on Hold - paused by a "!" command, need to be restarted by a "~" command
• Alarm - CNC doesn't know where it is and blocks all G-code commands

4.2 Control

Home button

Starts the homing cycle procedure with "$H" command

Z-probe

Starts the zero Z-axis search procedure using the command specified in the settings ("Z-probe commands" box). Example command: G91G21; G38.2Z-30F100; G0Z1; G38.2Z-1F10

Zero X/Y

Zeroes the "X" and "Y" coordinates in the local coordinate system. Also retains a local system offset ("G92") for later use.

Restore X/Y/Z

Restores local system coordinates with "G92" command.

Safe Z

Moves tool by "Z"-axis to safe position. Position coordinate can be specified in the "Safe Z" setting. Position must be specified in machine coordinates.

Reset

Resets CNC with "CTRL+X" command

Unlock

Unlocks CNC with "$X" command.

4.3 Software using steps

(1). Install the driver

For the first time use, please connect the device to the computer via USB cable, and click the CH341SER.exe file in the driver folder to install the driver. Under normal circumstances, the Win10 system will automatically identify and install the driver. For Win7 and Win8 systems, please install it manually.

(2) Set the port and connection

After installing the driver, open the device manager of the computer and click on the port option to see the content inside the red box on the screen shown in the figure below (the port information is in brackets).

Remember the port information queried above, switch to the Candle software interface and click the "Settings" option in the upper left corner. Selecting the setting will pop up the setting window. Under "Connection", select the port name you queried, select the baud rate 115200, and then click the "ok" to finish the setting.

(3). Complete connection

After setting the port and baud rate, click Finish. The status bar at the top right of the Candle interface will show Idle, and at the same time, the console at the bottom right will display the information shown below, indicating that the connection has been successfully established.

(4). Processing documents

Click "File" option at the top of candle, then click "New" to create G-Code. On the command bar at the bottom of the interface, click "Open" to select a G code file that has been made to import the file. After importing, the middle of the interface will display a visual graph composed of tool paths (the position of the pen-shaped graph in the graph is the current tool position). In the visualization window, hold down the left mouse button to move to rotate the graph, and hold down the right button to move. Graphics, scrolling the middle wheel can zoom in and out of the graphics. At the same time, the content of the G-Code will be displayed in the lower command bar. During processing, the machine will run one by one according to the G-Code commands.

(5). Fixture, tool installation and Set the working coordinate origin

The fixture in the product kit is not assembled. There are four sets in total. The appearance and usage of the assembled fixture are shown in the right figures.

Before running the G code program, you need to find the position of the engraving figure relative to the overall engraving plate. There is a three-axis coordinate system in the visual graphics. The origin of the three-axis coordinate system is the tool setting point of the actual processing graphic.

You can move the tool to determine the position of the engraving graphic relative to the overall engraving plate based on the position of this origin. The engraving figure in the figure below is taken as an example.

After the selected tool position is started, the X/Y and Z axes are reset to zero (the 10 10 are zeroing X/Y and Z axes buttons). Before returning to zero, make sure that the tool approaches the distance of one sheet of paper for engraving, and then return the X/Y and Z axes to zero (please use a flat-bottom sharp knife when engraving, and use a cylindrical milling cutter when machining planes, slots, and holes) The effect is that the sculpted figure will be carved with the blade tip as the origin.

The ER11 collet on the spindle motor should be clamped into the fixed head first, and it must be clamped in place. When installing the cutter, please do not extend the collet too much, as shown in the first figure below.

(6) Start carving

After finding the engraving position, click the send button below and the device will automatically start engraving. The status bar at the top right shows running. The visualization window shows that the tool is moving along the tool path. You can choose the pause and stop buttons below when engraving. (After pausing, click again to continue the previous carving. After termination, click Send to start processing from the beginning).

(7). Finished processing

After the processing is completed, the visualization window prompts that the engraving is completed and the time required for carving.

5. Offline controller (Optional)

Note: The offline controller and the computer cannot be connected to the engraving machine at the same time. When using the offline controller, please make sure that the USB cable of the machine and the computer is disconnected. The off-line controller has an external 12V standby power supply interface. When users use other mainboards with no power supply and weak power supply capacity, they can connect an external power supply to supply power to the controller

6. Restore factory settings

If the mechanical movement of the machine is smooth, but the engraving movement appears stuck, or the stepper motor does not move, please try to restore the factory settings of the main-board.

Method: Run Candle software and send command \$RST=* to the machine, then reboot the machine.

Problem Solution
Computer and offline controller cannot control the machine's normal movement or engrave abnormally	Check if the offline controller and the computer USB are both connected to the engraving machine. If so, unplug either the offline controller or the computer USB cable. Both cannot be connected to the engraving machine at the same time.
The machine is connected to the computer and powered on, but the engraving software shows a connection failure	Please make sure the computer has the correct driver installed; please check if the USB interface is properly connected; please make sure the COM port is selected correctly (do not select COM1); please make sure the baud rate is selected correctly (choose 115200).
The software displays an alarm error, the controller is locked, and clicking reset and unlock does not eliminate it	Check if the limit switches in the XYZ three-axis direction are pressed down or obstructed by foreign objects. Clean them if necessary. Alternatively, unplug the connection wires of the limit switches. If it returns to normal, the corresponding switch has short-circuited and failed. It can be replaced or temporarily abandoned.
The engraved content appears as a mirrored reflection of the original image, and the manual control movement direction is incorrect	Just set the Grbl parameters in the software to reverse the direction of the X or Y axis.
The engraved content appears rotated by 90 degrees	Check if the connection joints of the controller's XY axis have been swapped. Simply swap the connections back.
Problem	Solution
The engraved image is distorted and misaligned	Please check if there is any slippage between the lead screw motor axis and the coupling. Tighten the set screws on both ends of the coupling.
After modifying the engraving machine firmware parameters, various abnormal machine movements or abnormal engraving sizes occur	Please restore the firmware to factory settings. Run the Candle software, connect to the machine, and in the bottom right command box, enter and send the command $RST=*, then restart the machine.
