| + | * Do not leave laser cutter running untended for any reason | ||
| + | * Do not lift acrylic cover shield when laser is running | ||
| + | * Nitrogen back fill on mFL lab should be used when cutting materials prone to igniting. | ||
| + | * Confirm that the fume collection system is running whenever the laser is cutting or engraving. | ||
| + | * Laser lenses must be cleaned within ONE WEEK of time of use. If lenses has not been cleaned, clean before use to avoid damaging lenses. | ||
| + | ====Safe Operating Procedures Review==== | ||
| + | - Turn on laser cutter and fume extractor | ||
| + | - Use focusing tool to set bed height based on workpiece, move laser to desired starting position | ||
| + | - Launch CorelDraw and import 2D sketch as PDF or DXF. Take the time to check scale using built in page rulers | ||
| + | - Set lines to be cut as RED and patterns to be engraved as BLACK. (must use true RGB red and black) | ||
| + | - Select Print -> Print settings | ||
| + | - Within Print settings select desired laser recipe based on material and thickness, verify one click print is turned off, print order is set to inner features first, and import dimensions from CorelDraw is selected | ||
| + | - Click Print | ||
| + | - Navigate to Trotec software | ||
| + | - Check Scale, do a dry run without laser power if necessary | ||
| + | - Send job to laser cutter | ||
| + | |||
| + | ====Maintenance==== | ||
| + | * Mirror and lens mounted on cutting head should be cleaned once a week or before starting a job | ||
| + | * In body mirror (mirror #2) should be cleaned by Innovations Workshop staff once a month | ||
| + | * Acrylic top should be cleaned (inside and out) with Fantastik cleaner once a week DO NOT USE IPA | ||
