laser raster engraving

I have a chinese CO2 laser machine with glass tube and ruida controller.
I want to retrofit it to linuxcnc so i plan to buy a Mesa 7i93.
The machine works ok except of engraving that is poor quality.
I have seen an other machine that has the same glass tube and PSU with mine
but has a proprietary controller optimized for raster engraving and this machine gives perfect photo engraving results.
So the controller is the key to achieve good engraving this is the reason why i want to retrofit my machine.
The question is possible to do with linuxcnc raster engraving ?
I have seen this wiki.linuxcnc.org/cgi-bin/wiki.pl?Rastering_With_A_Laser but is old and some links not working.
I don't know rubby & python (i know java) to check the code but this old code (is from 2009) will work with linuxcnc 2.7 ?
Have anyone do with success a conversion like this and has good raster engraving ?

This is a good thread (printer port rasterizing..)

Thanks.
Iam interested in a mesa solution for laser not parport..
Is there a similar project with linuxcnc raster engraving and mesa hardware ?

It probably won't make any real difference once you have the motion sorted out. Assuming your machine is stepper driven, the 7i76 or 7i76e (ethernet version) is probably going to be perfect for you. From there it would just be renaming pins to suit the mesa card. I'd look at some of the plasma posts as it explains how to use M67/M68 to control various components via Gcode. Eg./ how to turn the laser on and off and adjust power levels.

Not yet - there isn't currently a way to get the laser trigger information streamed to the mesa card... I think it has been thought about - but no one has implemented it.

Is that sending pulses per mm of movement or something like that?
