If you are running a job and it doesn't appear anything is marking on your material and you can see the laser tube not firing we have a few items to troubleshoot for this.
Water/Lid Interlock not Engaged
On current model power supplies there would be an LCD screen on the unit which will show "Water Protection" being OFF when both Lid and Water Interlocks are not engaged and ON when both are engaged and laser is ready to fire, you will also see an additional LED lit next to the 6-pin green connector.
If this show Water Protection is OFF you can check below for more troubleshooting steps
Water Chiller
You will want to check your Water In / Water Out tubes to ensure it is correctly connected to the laser which would be Water "Out" from the Chiller to Water "In" to Machine and then Water "Out" from machine to Water "In" on your Chiller.
If the water lines are correctly connected be sure your Chiller is turned on and flowing water which you can typically apply some pressure to the water lines and feel water flowing within them.
In most cases the "Alarm Cable" going from the water chiller to laser isn't connected or is a loose connection as this cable lets the machine know the water is flowing, if you connect the cable and it still does not signal water protection is "ON" and the lid is closed then an important step would to check that alarm cable for continuity with a multimeter and see if the connection on those wires are good.
Lid Sensor
If the magnet lid sensor is "Flat" it's possible it wouldn't be making a good connection as there does need to be a slight slant to the sensor, about 5°-10° degrees, you can place a magnet on this sensor and check the power supply screen until it shows Water Protection "ON"
Mirror Alignment
You may think the laser is not firing as it is not marking the material but if you see the laser beam light up during this job it's possible the alignment may be off and clipping the inside of the air cone which the laser energy is not making it to the material.
A great way to check for alignment would to place a piece of thermal paper directly under the air cone (sticky side up) and do one test fire, you should have a solid circle pin-hole through your paper in the middle of the air cone hole. If you do not than adjustments to your alignment would be needed
Below are a few videos going over the process and a more complex in-depth guide is being developed to aid in further.
Bad Power Supply or Laser Tube
If Water Protection is "ON" and you test fire or run a job and no activity occurs through the tube or your mA meter on the front of the machine then the next check we can do is place a piece of thermal paper on Mirror 1 and go to your power supply and remove the 6-pin green connector on the power supply and push the Red test button to the left of it which will fire the laser tube.
This will fire the laser regardless of interlocks engaged or not, it is important to ensure the water is flowing or damage can occur to the laser tube without proper water cooling
If there is a mark the power supply and laser tube are good as it is firing but if it does not then power supply or tube can be the issue as they work together and you will need to create a support ticket below for further instructions.
