A link to someone using Mach3 for 3d printing.

When I have time!!!!!!!!!!!!!!!!!.

Nice find Mike thanks for sharing.

More reading for me to do.

Thanks Terry, who knows, I could be stalling out at the craft fairs later on in the year.

That's about it. 

( I haven't shown all the leftover parts that are thrown away).

You make it all sound so easy, go on and build one - after all, how hard can it be ?

Well, to state the obvious, have you checked that there are no tight spots or binding of the axis travel or cables / hoses snagging anywhere ?
Perhaps check your LPT parallel port cable for continuity and all other machine wiring for short / open circuit including any soldered joints and connectors. Major job checking everything but I think it has to be done.

My Boss took an early lunch today and while the cat's away..........

It took two attempts to get the tool radius offset correct but once I got it right the parts do fit pretty well.

I presume the toolpath looks OK on your Mach screen ?

Just something I tried during the holiday - as opposed to 'inlay' this is 'onlay' or laser marquetry.

This example is rubbish really because it was produced by cutting two identical images from different veneers and then transposing the parts. It has no allowance for tool radius offset so I have filled the kerf just to see the end result.
By thickening the outline of the original .dxf I should be able to produce two toolpaths (one for cutting on the outside of the line and one for cutting on the inside of the line) then, if I get it right, the parts should fit exactly with no visible kerf. 
A lot more experimenting before I get it right but it is an interesting technique and eminently suited to lasers.

As far as I am aware Mach will only produce the GCode it is given.
Autocad or other CAD/CAM is the place to improve your resolution as LazyCam has extremely limited capabilities.
If you draw your work and export as, for example, .jpg format then using other programs such as Vector Magic which are capable of generating extremely high quality .dxf files may be an option but there are many many alternatives to this and everyone has their own preferences.

Your GCode works absolutely fine here so the problem seems to be with your machine. Could it be an electrical noise issue ?
