Q: What should I do if some areas of the workpiece are not engraved?

Why are some areas of the workpiece surface not engraved? If you notice that certain areas of the workpiece have not been engraved, please check the following: 1. Check whether the material thickness is uniform. If the material thickness is uneven and the Z-axis origin is set at the highest point of the workpiece, some lower areas may not be engraved. It is recommended to set the Z-axis origin at the lowest point of the workpiece to ensure the entire surface is machined properly. 2. Check whether the cutting tool has broken during machining. If the cutting tool breaks during the engraving process, the remaining machining operations cannot be completed correctly, resulting in unengraved areas. Please inspect the cutting tool and replace it if necessary before machining again.

Q: Front Cover Open Warning

Front Cover Open Warning When the **"Front Cover Open"** warning message appears, it indicates that the machine's front cover is open. For safety reasons, the machine will pause operation. Troubleshooting: 1. Close the machine's front cover completely. 2. Click **"OK"** to close the warning message. 3. Return to the **BRAVOPRODIGY CNC Control System** and click **"Run"** to resume the machining process.

Question 5

Spindle Overload SOP: Overload Alarm & Spindle Fault Diagnosis

Accepted Answer

Spindle Overload Message Appears:
It’s a protective reminder of the spindle due to the program settings. Therefore, when the program detects abnormal load, it will appear as a reminder window to inform the users.
Please recheck if the toolpaths are well-set, or the barriers interfere with the spindle initially. If barriers interfere with the spindle, please move out of the barriers. Thereafter, follow the steps to get back to the original status.

First: Press the "OK" button, and the system will count down 30 seconds.

Second: After the countdown, it will return to the CNC software window, and users can continue to operate.

After you press OK, then the spindle will get back to normal operating status. This is the protection window of our machines, please don’t worry after you adjust it. If it shuts down suddenly, for instance, the spindle cannot run normally, the screen will show this reminder window as well.

If this phenomenon occurs, we suggest users provide more detailed information, namely machine model, serial number, operating process, etc. Moreover, please also provide recording references, such as photos, screenshots, and videos. This could help us to check in detail and assist you accordingly.

Check Whether the Spindle Is Faulty:
The following checkpoints are shown below, please check those correspondingly. This will help us to confirm in detail.

Adjust the Spindle speed percentage to 5%, close the cover, and press the spindle button on to observe if the spindle is running normally. If it does not rotate, please try to turn the spindle by hand, and then start it after turning it at different angles to see if it runs normally. (Please provide the screenshots.)
If it runs normally, please adjust the Spindle speed percentage to 50% and observe if the spindle is running normally. (Recording the screenshots.)
If it runs normally, please adjust the Spindle speed percentage to 100% and observe if the spindle is running normally.

Also, check if the fuse is burnt out or not.

Please provide us with the videos we mentioned above and provide recording references, such as photos, screenshots, and videos. We will based on the provided information resolve the issue accordingly.

Question 9

What should I do if the plastic material melts during machining?

Accepted Answer

What should I do if the plastic material melts during engraving?

If the plastic material melts during engraving, the **Spindle Speed** or **Feed Rate** may be set too high, too low, or improperly matched for the material being machined.

If melting occurs, stop the machining process immediately and perform the following checks:
1. Check whether melted plastic has accumulated on the cutting tool.
2. If plastic residue is attached to the tool, remove the cutting tool according to the instructions in the user manual, and carefully clean off any melted plastic.
3. Reinstall the cutting tool and resume machining.

Notes
1. The **Spindle Speed** and **Feed Rate** should be adjusted according to the type of plastic material being machined.
2. A worn or dull cutting tool may also cause the material to melt. If necessary, replace the cutting tool with a new one.
3. If you are using materials that are not supplied by BRAVOPRODIGY, it is recommended to perform a test cut first to determine the appropriate **Spindle Speed** and **Feed Rate** before starting the actual machining process.

Question 11

How do I use the "Current Line" function to resume machining?

Accepted Answer

How do I use the "Current Line" function to resume machining?

If the machining process is interrupted due to a power outage, an unexpected shutdown, or any other reason, you can use the **Current Line** function after restarting the machine to resume machining from a specific G-code line.

Procedure:
1. In the **Current Line** field of the **BRAVOPRODIGY CNC Control System**, double-click the field with the left mouse button.
2. Enter the G-code line number where the machining was interrupted (for example, **3400**).
3. Press **Enter** to apply the line number.
4. Click **Run** to resume machining from the specified G-code line.

**Note:** To avoid machining errors, make sure the workpiece is securely clamped and verify the work origin and tool position before resuming machining.
