Article on using the L-Cheapo as part of your tool-chain to engrave metals. Thought you might find it interesting.

It helped spark my memory that Inkscape was an easy way to go, especailly for engraving...could be a tad trickier for cutting since every color seems to cut better or worst, but I clearly was able to do it.

Did it work with the L-Cheapo if you did? I admit I never got aroud to it, because got distracted with other stuff. Seems the laser stuff is starting to peek my intrest again hehehe.

it's a updated custom version of image2gcode that can help us..

see joined, the source is also joined

It can lift off easy for when I am 3D printing and has a nice laser protected front window ..... and my cat who apparently thinks it's a perch for him. On the printer bed, I just have a canvas panel.

Though a 60w machine would be awesome,  but as you said far more expensive.

For my test I used the following settings:
- 8 passes
-0.05mm pass depth
- Speed of 25 mm/min (I maybe could of had it go a lil faster)
- Also note so it would have room to go UP I started placed my material( mand focused my laser) a lil below the very top. I chose to give it 20 mm wiggle room for the hell of it

The inkscape plugin seems the easiest way to do this for sure

So clearly leaving the path more complex seems better

I used the Inkscape plugin for this one. About an inch across. Not perfect but still looks nice in person.

To get it to show up I had to place the plugin files directly in Inkscape extensions folder (if overwrote something on my install, but didn't seem to break anything).
Below is a sample of my settings, clearly speed would vary. The directory would be wherever you want to save the files. 

- Pronterface seems to handle to generated gcode much better, I wouldn't recommend R-Host as it does not show where the image will be

- Set the Inkscape files to mm and the size of the file to whatever your bed size is, even if the image only takes up part of that space

- The inkscape plugin works on paths, so make sure you have selected a path

- generated gcode does not home your printer, so either manually home before an engrave or add that gcode on before you use it

- Inkscape plugin shows up under Extensions -> Generate gcode- > J Tech Photonics

- Seems sometimes when I was playing with it and I ran the laser tool consecutively on the same image  it was adding extra paths, so be careful of that you might have to undo a few times to make sure of that it is only sending on path in the gcode. It could have been the file I was working on or maybe user error..but just putting it in here just in case. For me last night since I was tracing a bitmap, seem if I wanted to run the laser tool plugin multiple times it was best I reload the image, retrace the bitmap into a path and then run the laser plugin again.

- While using the tracing bitmaps to make a path in inkscape, it works but I noticed it worked but I think I need to figure out some tweeks. One thing that helps is to simplify the path first before using the laser plugin.

- I have only tried it to engrave and not cut as of yet..

I think if I can try the cuts and make it work and maybe work out a few more things, this may be the way I go. It requires far less steps then I was doing before.

http://soliforum.com/i/?E1dcRSy.jpg <~~  My screenshot of my settings for the Inkscape plugin but I was only engraving and not cutting. If cutting I would increase the number of passes and make my pass depth 0.05 or maybe 1.0 depending
