Benbox Settings Issues Any Advice much appreciated
« on: February 25, 2016, 09:01:26 AM »
Hi All
I am desperately hoping someone can give me some advice with Benbox and my laser engraver

I have 2 laser engravers, both the cheap Chinese desktop untis. My first one is very small but works perfectly, however it does not burn any larger than a 4 cms so is only good for small projects.
The other one is bigger, but i am having a nightmare getting it to burn properly.
I have attached an image which shows the bottom text which is using the small engraver. not perfect but more detailed than the upper text which is burnt and not detailed enough.
i have looked at the benbox topics and have tried so many settings i  have got through countless tests. the top text was using the settings, low light 16, intensity 255, speed 2200, time 2, step 2, discrete on and laser on.

If anyone could advise on what i am doing wrong i would be very very very grateful. i am using jpg images if that makes any difference?

many thanks

@Waynerp

1. I assume you are using the Benbox software?

2. What kind of wood is it exactly? Regular plywood? Craft plywood? Birch plywood? Baltic Birch Plywood? Obviously thickness doesn't matter.

3. I see a small pattern that when going against the grain (vertically) some of the cuts are lighter than the horizontal cuts. This is because with these low powered lasers it is harder to engrave or cut against the grain vs going with the grain.

4. What kind of file is this? An image file? .bmp? or ?

5. What laser power settings did you try?

6. You tried both Discrete and Continuous?

7. And finally, you did focus the laser on the surface of the wood, right?

Is the laser focused? If not, do that first.

You didn't mention what power laser you have, but try these 2 settings:

Speed 800
Continuous
(faster but you lose some resolution)

and

Speed 500
Time 5
Discrete
(slower but higher quality)

Hi All

Apologies for delay in replying.

The laser is a "1600mW blue light laser "

The wood i am trying to burn feels and looks like a hard birchwood. It had a light coat of varnish, but i have sanded that off as i could see the laser was having trouble getting through it. 
In terms of focusing i simply adjusted the laser so the light is a small as possible while still in focus, if that makes sense.

Sorry yes i am using the Benbox Software.

That image is a jpg, not really sure what the best type of file i should be using ??

I haven't tried continuous yet, will give it a try tomorrow along with the settings Zax suggested.

Many Many Thanks for your help

Wayne

The BEST  ply to use is the LASER PLY.
 It is specially made for laser use.
 See my remarks on other section. (Why Cutting Wood is Problematic)...
Understanding the materials you wish to use  should be one of the first items on the agenda as using some materials can kill you (PVC is a no-no )  and some materials can damage/ruin the laser lens..

Lasers are wonderful machines..not ONLY  can they cut a finger off BUT  they can also cauterise it at the same time.....

I am in the UK..we have lots available.  Look for FINNISH  BIRCH..its reputed to be the best but make sure the stuff is for Lasers.

USA best bet is
http://naply.com/..They import it and --others in the US  also import the stuff.  In the US is  seems to be termed  LASER DIEBOARDS.

Google  LASER PLY USA.

Some advice given on a UK supplier site

 Please note that wood is a natural product and in the construction of plywood internal stresses are set up by the layers of wood which causes warp and bending, moisture content can make the bend and twist more noticeable but some bending and twisting is unavoidable. Leaving in a warm environment and storing flat with a heavy board on top will help minimise the warp.

When buying you really MUST make sure it is LASER PLY as this has different glue to normal glues between laminations..
Finnish Birch (the country!) is best.  Russian Birch Mmmm.........

By the way  3mm thick Laser Ply can be obtained in the UK   25 sheets of A4 size  (11.7 X 8.3 INCHES) 20 GBP  ($27.73) at todays exchange rate
