    Cool, thanks! Lots of good stuff out there!

    What a cool box maker...Unfortunately DRW only supports the following files: .lyz .bmp .emf ,png .gif .jpg .tif .wmf .pcx .jpeg .dib .tiff .tyz and so I could not open the file I created with the box maker. AND therein lies the problem with DRW. It does a good job of engraving jpg and bmp 's and it cuts out the stuff you create in it's limited dieter just fine but you can't download the thingiverse files .dxf or anything useful from the net! Like I have said before "not a software guy" and need someone to hold my hand to one of these other free programs that would be useful for downloading internet stuff.

    DXF to EMF Converter

    dxf to emf converter... not free

    inkscape will save as .emf

    be aware .emf is a more limited format than .dxf

    you get it free when you buy the controller...

    On this whole subject of controllers and software, it seems that the quality of the controller limits the quality of the software that can be used with it.

    2W 445nm Diode laser cutter/engraver in a suitcase-3mm-acrylic-gears-mp4_snapshot_04-58_-2015-01-a

    THis is a screenshot of the latest chinese controller, and as you can see, it's quite good, of course, there is also a full USB and Ethernet connection, and the software can also control the machine directly though either of those...

    BTW the speed showing is the "rapid" speed when pressing the motion buttons, and the power shows in the "pulse / test" power, not job power.

    It's a colour display so if you have a job with different layers, eg reaster engrave this at x, vector engrave this at y, and vector cut this at z, all will be shown in different colours, it also tracks current cursor / laser head position.

    Which controller? $83 is to much for me as I am saving cash money for whatever cheap version of Corel will work with the free Corelaser program that I think works with my controller, or a full on AWC608 conversion OR just sell this working unit with some instruction and go for a Redsail bigger 1600$ machine or one of the other suppliers that ships from the US. That said I don't even know for sure what Corel does? Like I said not much of a software guy. I did bookmark that page for the 30 free uses if something pops up that I just have to convert. For my hobby use "free" works or I just stick with the DRW for now. At least I don't have to learn it! There is a page on DRW I don't understand called printer or something like that. It acts like It wants to send something to a local printer? It has some additional capabilities I don't understand like colored layers (I know normally those would be used for cutting, engraving, different feed rates etc) but I haven't needed it and it doesn't seem to have any additional drawing functions (like French curves, an eraser, etc) so I have not messed with it beyond just clikcing on it to look at it. By the way I think DRW will "cut" bmps ok but it goes over and over thicker lines (actually I think I eliminated that on one cut with one of the "cut" commands. Something like minimum distance between lines or something like that) . Still faster than engraving by a bunch!

    By the way guys paint.net (free program) does everything I want it to do but I don't know if (for cutting) there is a better "save"function than bmp's. They can'tbe edited in DRW, just resized, rotated and engraved.

    Well that is cool. Where do you get that thing? Have you actyually bought and tried it and how much was it? And the big question does it require a dongle??

    it's standard in my new machine.
    IMHO it rocks
    no dongle or anything

    feel free to ask any further questions

    Can anyone direct me to a walkthrough on exactly how the Inkscape/LMN process works? I'm using Pronterface to send the gcode right now because my LCD controller is missing a piece. But, I can't seem to find any information on how you go from an image in Inkscape to generating correct gcode. I can't seem to make that file do anything with Pronterface. And, does this method allow for different colors in Inkscape to give different laser commands? For example, black is engrave, red is cut, etc? Any direction you can give on step-by-step Inkscape/LMN extension would be great.

    I don't need any instructions on Inkscape itself, but I can't find ANYTHING on how to use the LMN extension.

    I am using a laser from China that I have fitted with an arduino/ramps and installed the modified firmware from Dan (Adventures in DIY Engineering). My machine appears to be identical to the one modded on weistkengineering - I've used the same arduino/ramps and firmware detailed in that blog (no LCD controller, however).

    Any insight (in addition to the mountainsalready provided to this forum) will be greatly appreciated!

    I know I am late to the party but this seems to be my life in general lol. On the 40w CO² laser vs a 445nm (or even a 405nm) one huge difference is going to be what you can cut, sure it (blue laser diodes) will be as capable and even more so in some instances as the more powerful slower frequency of CO² but it will absolutely not cut anything clear, so glass and clear acrylic (no colored tint) are out, and blue is pretty hard if not impossible to cut too, the clear because it passes with no effect and will in fact burn what is on the other side, while the CO² sees the clear substances as solid black and is absorbed burning the material away. And I am sure it does wonders on blue even painters tape, unlike the 445nm unit.

    One thing you can use though to your advantage is to heat something up inside say a natural or clear PLA print (like doped carbon fiber or a metal substance that has absorbance capablity like titanium or say steel or tungsten but not aluminum power, as that reflects I think too much of the light to get any heat, as the beam will pass right back out of the PLA again with out heating it) and get it warm enough to soften the PLA so you can reorient it, like with a magnet near the outside surface, or throw down a clear glass or plastic case and laze something inside the case. that way you can control the air flow (or atmosphere) inside it with out effecting your laser head.
    I am using a 6040z CNC mill with parallel port input on my controller and applying an on off action to my second relay for now. but I want to add a break out board so I can use the step and directions from an arduino based 3D printer controller to inject pulses to the parallel port on it, and a laser engraver head controller output for a 15w 445nm laser, that I have been doing exactly what you were discussing with making stencils

    one issue is heat on laser heads, so I am looking to see if a water cooling block helps
    2W 445nm Diode laser cutter/engraver in a suitcase-img_0250-jpg2W 445nm Diode laser cutter/engraver in a suitcase-img_0251-jpg
    the laser head pictured is a 2.5w 405nm
    as for the reason for equal cutting power depending on what you are cutting (things that both will cut with ease) I think is due to the fact that the individual photons of higher frequency light, carry more eV potential so you are packing a lot more energy into the photons, while generating them requires the same level of power pretty much, along with the more power to beam of diodes vs that of gas based lasers, which waste a lot of the energy in randomization, thus its lost as heat coming out of the head.

    I have been looking into a lot of this tech and science, and found that if we could make high enough frequency photons, you could do a LOT of stuff that people just are not aware of yet. Unfortunately I have not been able to find a source for some exotic diode material like diamond diodes lol (222nm UV output ) anyway if it helps I can do a build log, at some point, and post what pictures I actually thought to take, for what I am doing now. if anyone is interested
