I’m thinking about pledging the $69 pledge (the arduino shield), but there is the small matter of having the time (and lack of experience) to keep building myself the machine I want.
I asked them about the raspberry pi needed for this project, apparently it’s for the G-code computation and web-interface,
so this can be replaced with the pc.

Did you see the smoke comming out of the material ?
Imagine that in our robox, it will fill up the box fast with vapor, and I don’t want to be around when you open it when all is done.

Laser cutter/engraver do not leave a residue per say, only smoke generated by the burned material, in so that the smoke generated will have its various negative properties such as smell (plastic/rubber/latex, or carry a certain amount of particles within.
What this means is that smoke that floats and finds itself between the laser ray and mirror will get burned/fixed onto the mirror (think wood resins for example), will in return will leave a physical trace onto mirror that can either lead to the laser burning thru the mirror or disperse the laser ray out of its targeted course, and that would be pretty bad.

So you definitely need air extraction to remove any smell and smoke floating in the enclosure and air pressure blowing on the targeted area to disperse any rising smoke.

To minimize risks a Fiber optic laser is a better solution as you reduce your risks of damage by smoke or particles, and has virtually no maintenance required, cleaning or calibration.

+1 for laser add-on, for engraving as I don’t see it working for cutting, mainly due to the platform base risking to be cut-out and fumes/smoke management requiring additional external equipment.

this said, a laser head is interesting IF it being of the Fiber optic guided type, the main reason is that it uses no mirror and therefor reduces the risks of the system being damaged by the smoke on the mirror, it also is much easier to manage its movements as there is only a fiber connected between the CO2 tube and the engraving/cutting head with no complex alignments to be performed on regular basis.

All in all, a laser head of the Fiber optic type seems rather easy to integrate without heavy modification or clutter inside the box.
