You mean the jumpers? I have 8 of them, I had a play around with them it made no difference unfortunately. I think the cache has mostly had it.

I want to replace the board really but its hard to...

It sometimes does it in roughly the same place. I am changing the file a fair bit to try and get round the problem. It seems to do image with just large blocks of black fine. Photos its really...

I engraved the tile image much larger the 'problem image' without anything going wrong. So its not the image size.

I also tried the 'problem image' it as a .png .bmp instead of a .jpeg and it...

Any idea on solving an engraving problem on a rabbit 3040 running newlydraw via parralel port.

The laser engraves the image fine in then all of a sudden decides it going to move up or down and...

Ok thank you very much. The red dot I have is just a small 5v laser diode I am sure you have the same or something similar.

Do you have a photo of it connected to the primary transformer? I am trying to install a ret dot on my machine (it had none before) so I am trying to work out where it goes.

I just used some stuff called sugru because that was the only silicone I had. It looks quite similar to the stuff you have in the pciture. I covered the soldered wire with silicone rather than using...

On a slightly unrelated note can anyone tell me the key difference between a 70 and 80cm 40w laser tube?

Is the larger tube worth the extra $60?

I seem to have a 1m tongli tube in the machine...

I had the same problem. At first any air in the electrical tape seemed to pop with the high voltage. Then I tried silicon insulating materials on the casing etc which worked for a bit.

In the end...

Well mine seems to be firing plasma out the side of it now so I guess its the tube :rolleyes:
I have a had that tube over a year but hardly used it so it must deteriate some degree by itself.

Do...

Can you tell us when you get the results of this bob?

I seem to have discovered a similar problem with my laser today.
Thanks

Is your old one dead? Or you building a new machine or something?

I came to the conclusion my one died by a process of elimination. However it was infact that the cheap plastic laser switch had...

I have borrowed anouther computer and it seems to work ok on that so I guess it was newlydraw/windows based problem.

My laser a rabbit 3040 running newly draw has picked up a new problem. It will engrave most of drawing I put in to newly draw. However it then will abruptly stop, try to continue again stop and then...

Looking at the state of my kettle after a few days after purchase I think I better stick with the deionised :)

I have seen barcodes on stainless steel before so I dont think you need a solid white background. I plan on doing this with my co2 laser with cermark. Though havent a barcode scanner to test it yet....

Did the cut ever work or have you just got this laser set up?

Do you have the correct laser selected type still when it was reinstalled?

I have newlydraw 1.5 but I have many more options than...

Thanks for all your responses they have been very useful.
I have sterilised the whole thing and bought a 25 litre drum of deionised water (couldn't find any distilled locally) cut the thing open...

Havent been using the laser for a while due to a lack of working control board. On deciding to replace the water I noticed the pump had a slimy kind of substance on it.

I have washed it but would...

The guy I bought my hx3040 was from Troon (he owns the art gallery there). My geography of up north isnt great but its closer than HPC.

I can help via the net if interested.

It can do vector and raster images.

I was hoping to run it from my mac using...

Thanks for help no success to report yet though. I have reinstalled newlydraw and tested the serial cable on my printer. The softdog is working because when I take it out it wont even let me load...

I had a problem where because they did not clean out the machine after they drilled the holes on it and some swarf got stuck in threads of the table machanism. So I took the screws out the the top of...

Does anyone know how the red dot alignment on the newer chinese machines work? Does it come attached to the laser tube or is it seperate? Could I possibly retro fit one to my existing machine?

Could I put a 60 W laser tube in a 40W machine like the 3040 I own. Would it be physically too big or just overheat etc?

I have a rabbit 3040 though the laser tube has just died on me. Where can I get a tube in the UK?

thanks zax15uk thats a great help.

When I import files from autocad in to newly draw does anyone know if i can change intervidual lines on the autocad work so I can e.g cut some and scan others.

What i am trying to do at the...

NewlyDraw with my rabbit 3040 can 'scan' (which is like a printer) and can cut vector lines too using 'cut'. Though I would far from recommend buying NewlyDraw its still pretty painful to use.
