I just received an S1 10-watt (with air asst and bed.) I am getting a little frustrated at finding a materials list specific for this model AND wattage. And answers to a few stupid questions like… if it fits can I etch it? For example: can I etch wood that is ½ inch thick with bark on it? I know I won't be able to cut that, but can I etch it?

The multi-wattage list I found said I could cut or etch some acrylics. Some acrylics? Okay, which ones? I know I can't put PVC or PET in the machine… and something about clear acrylic won't do something or another… what??? hunh??? Is there anything else that I need to avoid to prevent harm to myself, the laser unit, my home, etc? (Materials wise - I have read the safety booklet and know to properly ventilate and not try to operate without the lid and it becomes a class 4 if I use the riser base, etc)

So to sum up:

Can I get a specific material list covering all my options for only the S1 10-watt model? Combing through a table that has all the other options for the apparently very few options I have available is not happy-making.

 Also, is there a kit that I can use to convert to a 40-watt at a later time? I would need to upgrade the power supply as well as the diode I assume… Are those the only modifications that will be needed or are there more?
