You can either make some LaserCut Mechano with the scrap (files here: C:\Documents and Settings\Hackspace\My Documents\LaserCutMechano), put the scrap into the container on the right hand side of the lasercutter or, if the piece is too small to be useful, the 'landfill' bin in the workshop. | You can either make some LaserCut Mechano with the scrap (files here: C:\Documents and Settings\Hackspace\My Documents\LaserCutMechano), put the scrap into the container on the right hand side of the lasercutter or, if the piece is too small to be useful, the 'landfill' bin in the workshop. | ||
== Chlorine Testing == | == Chlorine Testing and Material Safety == | ||
It's very important that you only use safe materials on the cutter. | |||
Chlorine is a very dangerous gas used in the creation of many plastics (e.g. PVC) these are safe until heated; when they release the chlorine gas. The laser cutter will easily heat plastics enough to release chlorine, which will damage the internals of the laser cutter. | |||
For various information about safe and unsafe materials, please see the [http://www.atxhackerspace.org/wiki/Laser_Cutter_Materials|ATX Hackspace Laser Cutter Materials], and potentially [http://www.pololu.com/docs/0J24/3|Polulu Materials for laser cutters]. | |||
To test an unknown plastic for chlorine content try the following: | |||
#Heat some copper (wire's easiest) until red hot (do this for a while to remove any PVC that may be stuck to the wire from the coating). | |||
#Apply red hot copper to plastic so that it melts a little onto it. | |||
#Heat copper wire until red hot again. | |||
#A green flame means that the plastic contains chlorine so do not use it. | |||
