Laser Engraver Forum

Hello Tom, Yes, the air pump is running and supplying air to the nozzle. Although, it could not be supplying its full potential because of the way the tube is reduced to the correct size airline. To go from the tube exiting the pump, to the smaller tube that connects in the back of the laser, zip-ti...

Hello Tom, Laser is still running quite well. We are having one issue with the focusing lens though. It keeps cracking. We have gone through all the spares. They should not be breaking this easily. I had noticed before, that some of the paper that was used for focusing had burnt off and fell onto th...

Hello Tom, I took a look in the laser head. Found a cracked lens and replaced it with one that was supplied. (See attached pictures) Then refocused the beam. As far as I can tell the machine is running the way it should now, I was able to cut through our gasket material. I still need to play around ...

post the image you are trying to etch.

Tom, To answer your questions: Yes, the chiller is now running using 220V (See attached photo). This stopped the beeping and it seems to run very well now. I did some vertical position tests with paper and the best results happened around 3mm away from the tip of the nozzle. However, it was still on...

Hello Tom, Good news, we are now supplying the water chiller with 220V. It no longer beeps and the “normal” light it on with good flow. The bad news. Laser still does not cut. I did the focusing as shown in the video you linked to me from a while ago, and I would say it is in focus. The attached pic...

Hello Tom,

Sounds good. I will do the focusing in the next day or two and reply back.

I really appreciate all the help. Thank you!

Hello Tom,

We put the magnet to the flow switch and nothing changed. It still beeps.

We did notice that It’s input, after looking around, is required to be 220V. We are currently running 110V 60hz into it.

I will continue on with checking the focus of the laser.

Hello Tom, I did the quick test you suggested by connecting the output of the chiller to the input of the chiller. Unfortunately, the chiller still beeps. The good thing is that it pumps water. Do you think there could be a flow issue with the heat exchanger? I took the cover off and noticed there w...

Tom, Correct, there is no alarm code shown on the display. (E1, E2, E3….) I have seen the same diagram in the manual myself. The water level is at the upper limit of the green section. I don’t think it’s a matter of water shortage. Yes, the water flow is good and strong. According to this table, “Fl...
