Thanks yes I emailed them same time I posted in this thread and they replied one hour later, saying they did have 85mm tubes, didn't say what power output though. $455 US for one tube and power...

Hi gfacer - thanks for the advice, sounds like a bit of a bugger you had, hope I have more luck.

Did you have to contact DHL directly to organise an airport pickup option?

I bought 50W laser cutter / engraver. I believe it's either a Shenhui brand or a copy. It is no where near as powerful as I was led to believe. So I bought a Mahoney power meter and found the...

have you tried the fuse in the laser power supply box? I saw a fuse in the box while I had the cover off.

You can also check the milliamps to the laser using an everyday multimeter. there is a...

Its helped a lot, I can get almost there now. so...

Some time ago I bought a Shenhui laser and while the power out put is about half of what is stated mostly it cuts thin card which is what I need. It took me a long time getting the machine to an...

don't know if it will help, if it were me I'd be pulling out and checking every plug and putting back in again.

Hi Shenhui and fixtureman
I've received my laser power meter today but it says I need to make the laser shine on it for 29.1 seconds then take a reading 30 seconds later.
Any ideas how you set the...

Hi fixture man, not sure what you mean or what your post is trying to solve. Is it my output problem?
Do you mean swap all the neg's for pos's and vice versa?

I've just gone and tried to do...

Spot on Shenhui Laser!
I checked everything and found that there was a bit of play on one side of the y-axis arm.
The right side along the runner seems to be quite solid, but the left side I could...

I've played around with belt tensions and my settings but still not right.
my circles are still a little wonky and if I cut say 4 small rectangles, depending on which corner it starts cutting, it'll...

@EXLASer Hi thanks for replying, I've managed to correct the ypulse which has definitely helped a lot.
Still not right but much better. Manufacturer had told me something like this before stopping...

Hi Shenhui,
No not solved power issues yet but have looked up lenses and agree it should point up. It is a concavo-convex lens, similar to eyeglasses - light should hit the outside concave side and...

my step lengths were different but I can see they are different on your settings too. Fixturemans are the same. I cut 100mm square and inputted the expected versus actual dimensions into the box as...

Thanks Shenhui, couldn't check last night, it got to about midnight so I went to bed!
I run my laser cutting business in my spare time - I won't be able to get on to it until Wednesday evening as...

I bought a laser cutter/engraver, had a few issues getting it working and they have now been solved.
So I thought I should start a new thread.

My laser cuts inaccurately. Period.

Hi Shenhui, Thanks for trying to help. Please see my responses below.


This issue has been solved thank you.


Are you referring to cutting through the rubber or just engraving on the top? If...

Hi Fixtureman,
Sorry for taking so long to get back to you.
I tried that setting and didn't achieve any better. I don't get it, in your expert opinion should a 50w laser be able to cut 1 mm rubber?...

Hi Ralf and fixtureman1,
The laser definitely moves back into position and I've found in the settings an x-mirror and y-mirror setting that was ticked so have played around and got it to cut the...

Yes in an earlier post I mentioned the arrow buttons move the head in the right direction so I think it must be software. I still need to double check the head moves home on startup but I'm pretty...

No the laser button didn't fire but I've finally sorted out with the help of the manufacturer. Seems like a small plug that is very hard to see, (tucked out of the way), was not in properly. It sends...

Thanks for the help and the information. Great to know there are still people out in the world willing to give up their time at no benefit to themselves.

I've finally got it up and running, see...
