CNC Troubleshooting Tips

Even the most reliable machines require servicing, repairs, and a little TLC over time to stay functioning properly. Let’s examine a few common issues CNC machines can have and how to identify the root of the issue.

Common CNC Controller Problems

Troubleshooting your CNC Machine? Start by examining the controller.

Controllers are essential to the function of many CNC machines and might be at the root of the issues you’re having with your setup. A few of the most common problems we see in CNC controllers are:

Damaged Exterior
Overheating Machinery
Vibrating Components
Poor Programming
Lack of Maintenance

CNC Machines require regular service appointments to clean, lubricate, and calibrate the machinery to prevent damage. If you’ve skipped a few appointments, that may be the root of your problem.

Common CNC Machining Problems

Not the controller? Let’s dive into other common trouble areas.

CNC Machines are electro-mechanical devices that control shop tools using computer programming. These machines have a large number of parts that may be included based on your specific usage and therefore have a wide variety of areas to troubleshoot. Some of the most common problems we see in CNC machines are:

Improper Maintenance
Machine Tool Failure

Troubleshooting a CNC machine DC Motor

If you suspect the DC motor is the root of your issues, troubleshoot by examining these areas and you may uncover the problem.

Check The Brushes

1. Remove brushes and springs.

2. Brushes should move freely as you remove them.

3. Check spring tension is equal.

4. Examine the brush face, are they clean? If not, replace it.

5. Examine brush length, they should be 7.5 inches.

6. Shine a light inside to check for buildup, and use an air cleaner to clear the area of any debris or dust.

7. Examine the grooves and replace any with substantial wear.

Troubleshooting the Emergency Stop

If you can't get the emergency stop to clear on your CNC machine, troubleshoot using these steps to identify the problem.

Clearing an Emergency Stop

Check The Brushes

1. Make sure the conveyor is plugged in and that the power cord has no signs of damage.

2. Pull out or push in any emergency stops, check for any issues with the conveyor, high-pressure unit, gantry, and barfeed as well as checking for blown fuses in the electrical cabinet.

3. Check for axes near the overtravels.

4. Inspect the door interlock mechanism and any other interlocking modules.

5. Check that the LED light is ON and says POWER (or similar).

6. Make sure power supplies are active, and check that there isn't an electrical shortage. Dim or burned-out LED lights may indicate a low power supply.

7. Locate and follow the E-string to see if there is a voltage issue.

Troubleshooting a Problem with the Power Supply

CNC equipment often has multiple sources of power, if one or more are compromised, that may be the culprit behind the malfunction.

How to Check CNC Machine Power Supply

If you're not sure where to find each power source, these locations are a great place to start:

1. Behind the CRT screen

2. Door interlock circuit

3. I/O card

4. Individual power supplies for drives, spindle

5. External power supply

You'll need to check for input and output power for each of these sites. Almost all power supplies will have an LED indicator light, but it's best practice to confirm the power levels with a meter in addition to viewing the light.trong>Unable to clear the emergency stop?

Troubleshooting Code Errors in CNC Machines

CNC Machines are computer-driven and require accurate programming to prevent errors in output. Programming errors can cause everything from minor glitches to irreparable damage if not properly coded. It's critical to hire expert CNC coders as well as machine operators who are well-versed in their machine's user manual to prevent coding errors.
