| - | ====Creating New Material Recipes==== | ||
| - | Please ask a wizard for assistance in creating a new recipe as there is a great risk of fire. Only create a recipe on your own if given approval first. To create a recipe for a new approved material, begin by doing research on what power and speed is generally used for your material. Be sure to account for the differences in speed and power of the printer you’re using versus the printer which you found the material recipe for. Your recipe will be a Speed(0-100%) and Power(0-100%) setting for both engraving and cutting your material. Cutting will need significantly more power/less speed than engraving. Remember that a lower speed will result in a higher cutting intensity and vice versa. To make a new recipe, click the setting menu in JobControl select Material settings. Create a new recipe for each color indicating whether it is cutting or engraving. Many recipes are already available for use/ | ||
| - | ====Printer Maintenance (For wizards only) ==== | ||
| - | __Lens and Mirror Cleaning__ | ||
| - | Printer Lens and Mirrors must be cleaned weekly to remove the buildup of dirt and dust and prolong the life of the lens and mirror. There are two mirrors however mirror #2 requires removing the right side maintenance panel and should only be cleaned by IW staff. Always check Lens cleaning log before printing and ensure the lens was cleaned at least 2 weeks before. To clean the lens and Mirror #1: | ||
| - | - Ensure Laser cutter is off | ||
| - | - Wearing Nitrile gloves, remove the lens from the head with cloth/ | ||
| - | - Blow off any dust from lens with compressed air | ||
| - | - Wipe lens once with lens cleaning solution and lens wipes found in the Laser cutter bin | ||
| - | - Put a drop of lens cleaning solution on lens and let sit for a minute before wiping off | ||
| - | - Repeat with other side of lens | ||
| - | - Replace the lens in the correct orientation with concave side pointing up. | ||
| - | - Remove the mirror using the set screws and clean in the same fashion as the lens. Replace mirror | ||
| - | - Log the cleaning of the lens and any additional notes such as condition of the lens in the lens cleaning log | ||
| - | |||
| - | __Particulate Filter Change for Atmos Compact__ | ||
| - | - Turn off the Atmos and unplug the main. | ||
| - | - Open the filter housing, the black drawer will be seen on the left. | ||
| - | - Unplug the measurement hose (connected to the front of the drawer) and carefully pull the drawer out of the housing. | ||
| - | - Unscrew the front of the drawer, this area is the activated carbon housing. | ||
| - | - Remove the activated carbon and the filter mats (located on the sides) into a disposable bag. | ||
| - | - Place the new mats in, noting that the blue imprints should face the exterior of the drawer. | ||
| - | - Pour in a limited amount of activated carbon. If the mats stay in position, proceed to fill the container with activated carbon. | ||
| - | - Close the chamber with the fasteners. | ||
| - | - Slide the drawer back into the filter housing. Make sure that the filter is sitting firmly and is attached airtight to the back of the housing. | ||
| - | - To reset the error signal, press “+” and ”-” on the control panel consecutively for 3 seconds. The LED should then read “Activated Carbon OK.” | ||
| - | |||
| - | Note the following when conducting maintenance on the Atmos: | ||
| - | * All waste from the compact must be labeled as hazardous before disposal. | ||
| - | * A more detailed list of all the error commands on the exhaust system can be found on page 40 of the manual (linked at the beginning of the SOP). | ||

| - | |||
| - | ====Safety Concern==== | ||
| - | * Looking directly into the laser can cause retinal damage. | ||
| - | * Do not cut unapproved martial including PVC, Metal, HDPE, compost materials containing epoxy, anything whose composition includes Chlorine or Florine. | ||
| - | * 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 | ||
