| + | * How to format your SVG drawings for K40 Whisperer: https:// | ||
| + | * Basic concept- using K40W, move the head over the upper left hand part of your work. maybe use the "laser test" button to make sure you're actually over the work. and then choose whichever of your engrave/cut options (do engraves first, and cut last). | ||
| + | * Specialized documentation: | ||
| Safety considerations: | Safety considerations: | ||
| + | * NO ABS - Cyanide gas is bad for you! | ||
| + | * NO PVC OR VINYL-BASED MATERIALS - Chlorine gas is bad for you! | ||
| + | * Wood and Acrylic are OK. ATX Hackerspace has a recommended list of materials [[http:// | ||
| + | |||
| + | Power levels: | ||
| + | * Wood (engraving) - 8% does a fine job on the random wood pieces we've tested with. | ||
| + | * wood (cutting) - 11% was sufficient to cut 3mm baltic birch plywood? | ||
| + | * Acrylic - 25% was great for engraving, but slightly insufficient for cutting (the cut edges did snap off easily, though). 33-35% should be good for cutting at 10mm/s. | ||
