The quality of the etching is quite poor. Missing and faint lines yet significant smearing outside the letters. Are you etching characters that are outlined? Can you post your source?

If you stain prior to etching it can help keep the soot from falling back into the grain of the wood. It may also increase the energy needed to burn the wood.

Thanks Zax - I will try those options on this.

Gallant - I think a lot of the issues you are noticing is all based on how i printed it & not having "Dynamic" mode activated on the laser.  I'm learning as i go.  The burning tends to happen when i have Bold Print & the faintness happens when there is a thin line it seems.  Honestly, those issues don't bother me too much. 

Also - i didn't have the letters outlined. I learned that this happens because that's where the laser 'starts' and 'ends' every time it begins etching.  I believe activating 'dynamic' will reduce this in the future.

Since i have 100 of these i'm going to move to the next one. I assume i'll get better as I go.  & this gives me the option to come back to it somewhere down the line.

Appreciate all the help.

PS:  I added the final picture below.  In future, I will probably cut a hole through the wood to make the card almost flat w/ the wood.  I'm welcome to any suggestions.

to have the exact positions of the parties make three copies of the total image, to each one eliminate the 2 unwanted parts. you will have a large empty space with the only part to be engraved. however the origin of the three images will be the same

Thanks Guys.  I will most likely try your image idea.  Should have thought of that myself!  Seems i also should start looking into vectors as it may help w/ engraving.

Zax - Thanks.  I will use that option on my future boards.

So the 45 degree angle thing is still causing some issues. I noticed that when the laser is only going about an inch away, it is very much tuned in; However, the further i go away the worse it gets. Like once i hit 2 inches away, the accuracy worsens.

Notice how the word Schmidt looks pretty good prior to the Jack and Mike.  That's cause it finished w/ the 3 at that point and could just concentrate on that small area.

See attached photo

Also: Is there a way to clean this up? maybe by staining it? or should i chance going back over it by hand w/ the laser on a  low level?  I have 100 of these to make so. i'm actually not unhappy w/ this product for now. need to move on to some next ones. just want some ideas to make it a little nicer.

I appreciate all the help

When you say "engraving" are you talking about an image or vector?

The answer is yes for either but the process would be different.

Zax - I will be working with an image.  To break it down more:
Top of image - a Picture
Middle of image - a paragraph
bottom of image - a few Large numbers.

So ultimately im trying to minimize the effort from the motors on the laser.  Instead trying to keep it actually engraving most of the time. before moving across the entire sheet.  The only way I have been able to succeed at this so far was to cut up one of my own images and then do the engraving in parts.  The only issue with this is, i'm guessing where to put my board. So the actual distances apart are not perfect.

what are the steps to enable dynamic Laser power?  Does that also help w/ gradients?

I typically have a good picture when i do it horizontal, but the 45 degrees tend to look a bit cleaner.   Here is another image after tightening some things up.  Should i be concerned how tight i make them? i feel it did work somewhat.

Update:  I continued tightening somethings and made sure the wires were not hitting this device at all and I believe i am back on track w/ good 45 degree angles again.  I literally went through and tightened everything up across the entire machine.  (Thanks for recommending that).  **Still interested in figuring otu dynamic laser power option

So yesterday I printed a small piece at 45 degree angles and it came out amazing.  Today I did it and it's coming out like crap.  I have gone back and re-tightened all of the motor teeth up.  I am wondering if anyone thinks it could be something else.

I'm working on a fairly large engraving and the engraving is really divided up into 3 areas. (top) (middle) and (bottom).  There are wide open areas on some of the wood that don't require any engaving at all.  So basically it will engrave (.2 inches) at the bottom. Then scroll all the way to the top and engrave another (.01 inch) for the next item.  Is there a  way to have the engraver concentrate on designated areas.  It would be great if i could highlight sections to be engraved first second and third, etc..

My concern is that the engraver running around this much will loosen it's bolts and possibly mess up half way through.  When it's all engraving closer, there is more working and less running back and forth.
