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
In most cases one of these icons would be red which would not allow the laser to fire.
Water Lines/Pump
If the water icon is Red you will want to check your Water In / Water Out tubes to ensure it is correctly connected to your Hobby Water Pump or Coolbox unit, this would be Water "Out" from Pump to Water "In" to Machine and then Water "Out" from machine to Water "In" on your Coolbox or into a bucket if you are using a Water Pump.
If the water lines are correctly connected be sure your Water Pump or Coolbox is turned on and flowing water which you can typically apply some pressure to the water lines and feel water flowing within them.
Water Sensor
It is possible the water sensor itself may be dirty/clogged so it wouldn't be spinning at the correct flow rate to trigger it to be active.
You can remove the water sensor by unscrewing the 3 screws and clean the inside with a Q-tip and once it is reassembled and installed correctly with the embossed arrow on the water sensor facing to the right this would rule out being a dirty water sensor.
Next, open the right side panel of the machine and locate the "WATER" wiring and reseat this connection which is near the bottom of the green control board.
If the Water icon is still Red it could be a faulty water sensor or wiring to the controller board or the control board itself and if you are having a issue here we can troubleshoot further with a support ticket
Lid Sensor
If the lid is open and closed and the icon will stay Red and not engage it would be a good to try another magnet placed on the Lid Sensor itself near where the lid closes to see if at any point it does change from Red. Also, opening the right side panel of the machine will allow access to your control board where we can locate the "LID" wiring on the top of the green board and reseat this to ensure a good connection is being made.
If the Lid icon is still Red it could be a faulty Lid sensor the control board itself and if you are having a issue here we can troubleshoot further with a support ticket
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 both your Lid and Water Interlock icons are not Red it would indicate they are active and the laser should be able to fire unless an issue with the power itself or laser tube itself.
Place a piece of paper on Mirror 1 and open the right side panel of the machine and locate the "LASER" wiring on the green control board and unplug this cable and then on the black power supply to the right of this connection there will be a smaller Red "TEST" button on the power supply and once this is pressed down it will fire the laser and you may check if there is a mark on Mirror 1
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.
