[[User:Tetsu|Tetsu]] worked hard and started a [http://www.kickstarter.com/projects/211646812/laser-cutter-for-familab-fl-hackerspace?pos=1&ref=search Kickstarter project] to get us a laser cutter for about $2000. We successfully promoted it enough to get people to generously donate to our cause, and now we have one!

Lots of people worked on this (sorry this was before I was here so I don't know all the details).

==Learning==

* Plastics:

* [http://familab.org/wiki/index.php?title=Laser_for_Newbies FamiLAB Laser for Newbies]
+
** ABS (acrylonitrile butadiene styrene)
 +
** Acrylic (also known as Plexiglas, Lucite, PMMA)
 +
** Polycarbonate (PC, Lexan) — Beware the fumes on this one, they can get pretty bad.
 +
** Delrin (POM, acetal) — for a supplier, try www.mcmaster.com.
 +
** Kapton tape (Polyimide)
 +
** Mylar (polyester)
 +
** PETG (polyethylene terephthalate glycol)
 +
** Polyethylene (PE) — melts badly
 +
** Polypropylene (PP) — melts somewhat
 +
** Styrene
 +
** Two-tone acrylic — top color different than core material, usually for custom instrumentation panels, signs, and plaques.
 +
 
 +
* Foam:
 +
** Depron foam — often used for RC planes.
 +
** EPM
 +
** Gator foam — foam core gets burned and eaten away compared to the top and bottom hard shell.
 +
 
 +
* Other:
 +
** Cloths (leather, suede, felt, hemp, cotton)
 +
** Magnetic sheets
 +
** Papers
 +
** Rubbers (neoprene) — for a supplier, try www.mcmaster.com.
 +
** Teflon (PTFE, Polytetrafluoroethylene) — for a supplier, try www.mcmaster.com.
 +
** Woods (MDF, balsa, birch, poplar, red oak, cherry, holly, etc.) — for a supplier, try www.midwestproducts.com.

Things we '''''CANNOT/DO NOT''''' cut:
 +
* Metals
 +
* Any material containing chlorine
 +
* PVC (Cintra) — contains chlorine
 +
* Vinyl — contains chlorine
 +
* Fiberglass
 +
* Printed circuit board (FR4 and other material types)

To add a material, make sure you follow the convention of the current materials. Each row should begin with the |- character on a line by itself, then followed by a pipe ( | ) character at the beginning of each column. Make sure you have a pipe character for each column even if you don't put data in there (the notes column for example)

==Modification Suggestions==
 
−
Our FullSpectrum 40W is far from perfect. Add your suggested improvements to the laser cutter on this list.
 
−
* <del>Mount the parallel port driver board further back within the case</del>
 
−
* <del>Mount the Mach3 card inside the case, make cover for it to screw in the outside (with the laser cutter!?)</del>
 
−
* <del>Strain relief and longer USB cable (Chris has a 10 or 15 ft he will donate. Ferrite beads and gold plated.)</del>   
 
−
* <del>Air pump (Mack getting this for us so ghetto-rig ShopVac can go away)</del>
 
−
* Digital readout for power knob (Looking into digital potentiometer with readout!)
 
−
* Lid-switch should trip the system-wide cutoff, not just a computer control cutoff
 
−
* IR-sensitive webcam in the box
 
−
* Beam-split red laser upgrade to point where the laser will point (Chris will work on this as well as a laser to show where the corner of the piece will start.)
 
−
* More stable/level platform
 
−
* Locate more metal honeycomb without frame
 
−
* Millimeter (digital?) measurement tool on the side of the platform to automatically measure height of platform
 
−
* Laser-cut (58mm?) focus measurement stick
 
−
* Back-lit switches for the "Laser Power", "Laser Test", "Air Power", and "Light", so we know when it's actually on
 
−
* Shiny aircraft switches (Safety to keep from bumping), with led notifiers above
 
−
* Water pump flow sensor and light, integrate with Laser On switch to prevent operation if a problem is present.
 
−
* Knight rider LED chaser for when laser is active and lasing and dangerous
 
−
* Better interior lighting (possibly fluorescent bars and/or LEDs) to better light the work surface
 
−
* Possibly redo entire control panel with digital readouts and better (read: safer) switches.
