I am hoping someone can help me, because my laser cutter is driving me insane.

I have spent days leveling the machine, aligning optics. I have replaced, my tube, my power supply and my optics, and...

Thanks Bill and Jeff. I will have to take that into account. Will probably mean I have to install a aircon, or at least a dehumidifier.

Looking at the predictions it looks like we are going to...

Hi Jeff

I am from Durban South Africa, It does get quite humid here. Especially in Summer. I wouldn't say I have a lot of condensation, but I did notice today that I had a bit of condensation...

Thanks Bill. I do have a spare power supply, so I will swop that out in the morning.

Kev, I think I have the laser as level as I need, might try a few small adjustments, but I am not going to kill...

The last time I leveled the machine I obviously did it wrong. I leveled the machine taking measurements on the bed, but measuring now I see that the rails and the gantry are not level. I have...

Hi Rich

I have added my machine details to signature, so I hope that helps. Its not a new laser, I got it back in 2014, but I have been plagued with various problems since I got it so have never...

Thanks Bert.

I have read through that link before, but it does not have any information that addresses my specific problem.

I have spent the day trying to properly align my lasers optics but have run into a small snag.

I have managed to get 3 of the 4 corners of the bed (top and bottom left, and bottom right) to hit...

I am having some firing issues with the 80W Reci Tube on my Shenhui SH1390 Laser Cutter.

I am almost certain that the laser tube has seen its end. I have had more than one tube fail prematurely,...

OK I am going to try and respond to all questions in one go.

Bert, I am running the laser at full power and the tube is about 14months old, but it only has maybe 200hrs of running time on the tube...

Since getting my Shenhui Laser I have been plagued with problems which have not allowed me to run my machine reliably for any prolonged period of time, not good a it was supposed to be my main source...

Hi All

My brother has a small 40watt K40 laser cutter which has been down for sometime now and he is wanting to get it sorted out to sell.

The problem we are having is that the laser is...

Hi

I am trying to make name badges to supplement my business. When I apply clear printed vinyl to the gold rowmark I am getting a mottled look which i think is from the glue as when I run my...

Hi All

I have been to the doctors and done a breathe test and the doctor has assured me that i am in the clear.

Thanks to everyone for there advise, an important if not somewhat terrifying...

Thanks Dave

I will definitely go for a check up tomorrow, if anything just to ease my mind. The mask I have is a 3m half face mask with 6075 A1 filters for organic compounds and formaldehyde. But...

I work from a double garage. I work with both of the garage doors open and with the vent hose blowing out of the door. Unfortunately the hose I have only just reaches outside. Most of the fumes were...

Mike thanks for the input, it has put my mind at ease a little. I will however be booking a doctors appointment for tomorrow just to make sure.

I will definitely not be cutting anymore pvc at...

Well now I am terrified of the damage I may have done to myself. I wish I had asked this question earlier. I though I had done my research, and people had seemed to think that a one off small job...

I am definitely worried about my health. I did try and spend as much time outside as I possibly could, but I did still feel some ill effects. I am even anxious to continue using the machine now until...

Hi All

I was asked recently by a client to cut a small amount of PVC backed reflective perspex. After reading up, I agreed to do it because it was a small Job and I thought it would not cause any...

Hi

I am having a problem at the moment with my laser not cutting straight, I think I know what has caused this, but I am hoping someone has a solution for me.

I know that setting the last...

After much tinkering I finally got my engraving to an acceptable level, but alas it seems it was not meant to be. I was engraving some awards on clear acrylic (plexiglass) and everything seemed to be...

The tube only hissed twice. Now the tube is not firing at all. I have had a technician come and look at the machine. There is no sparking anywhere, we have swapped power supplies and still not even a...

I have read through the shenhui thread, and cannot find anything. I tried again this morning, when I pulse the laser I get a very small hissing sound from the tube, like it sounds when it is firing,...

I have had a shenhui laser for about 7 months now, and have battled with it from the get go.

I finally narrowed down the problem to the tube, and have been sent a new one which will arrive in the...
