I have no laser signal

Hello.
i have bought a new Co2 laser,
i filled up the water, did all the thing that are in de manual.
i can move it and all with Lightburn.
but i dont get the cutting beam to the front.i cant cut.
if any one could know what is the problem, please tell me.

thank you.

What specific model of laser is this?

Are you saying the laser isn’t firing it at all? Or are you saying the laser doesn’t make it out of the nozzle?

Some lasers have a key that you need to turn to enable the laser power supply. If you have this, you will need to turn the key to activate the laser.

Does your laser have a pulse/test function? If you use it, are you able to mark the your material?

Finally, are you getting any messages in LightBurn or on the laser’s display panel?

yes i know . i have a swich,to turn on the power suply for the laser. and the air outtake is then turned on and the air on the nozzle. yes i have the Pulse option, but nothing happends.

i tryed to engrave smething ower lightburn, and the laser is running throu the data ,program, i wrote, but it is not engraving or cuttung

Are you getting any message from either LightBurn or on the display panel?

Try a test please. Place a card or masking tape in front of mirror 1. That’s the closest to the tube. Then run a test pulse. Does it make a mark? If so, proceed to mirror 2. Does it make a mark? Proceed to mirror 3.

In addition to what berainlb has suggested, if your high voltage power supply has a current meter (mine does, some do not) you might want to check to see if it’s reading any current, at all, when you pulse the beam. Normally the control panel will show you what the power is set at for a pulse.

thank you all. i figured out. one conector wasnt atached to the laser power source. thank you for your help
