| + | to be integrated in to page. | ||
| + | - Never leave unattended | ||
| + | - Always use the Emergency Stop button that is on the laser before the one on the wall, and especially so in emergency - this allows the water cooler and extractor to stay on and help put out any fires, reduce damage, etc. | ||
| + | - Laser MUST be below 24c, better to be less than 21c. Read the temperature from the refrigerator unit. In the warm months, it can take 10+ minutes to come down to temperature. | ||

| + | Materials: | ||
| + | - [[: | ||
| + | - Absolutely no PVC. The " | ||
| + | - It won't cut steel or aluminium | ||
| + | - it can supposedly surface engrave anodized aluminium, or alumium that has been treated with a special spray. ask around on the forum before attempting to do so. | ||
| + | - Acrylic 4mm will be cut through at 12-15mm/s | ||
| + | - If you're unsure of laser power, do test cuts e.g. a few squares in the corner of your workpiece to work out how slow to cut through | ||
| + | |||
| + | Files: | ||
| + | - Must export in DXF | ||
| + | - Must be in mm | ||
| + | - Open Lasercut5.3 on the PC. | ||
| + | - Import DXF | ||
| + | - Tools > unite lines. | ||
| + | - Change scale, type X width then click 3 dots on y to set proportional scale. | ||
| + | - " | ||
| + | - Use different colours to create layers | ||
| + | - Double-click colour to open options | ||
| + | - Generally always blow | ||
| + | - Speed is measured in mm/s | ||
| + | - Corner power - can reduce | ||
| + | - Layers work in order, top first. | ||
| + | - Generally want to engrave then cut, to prevent movement. | ||
| + | - To just engrave, put 70mm, 50% for acrylic | ||
| + | - Engrave Mode setting will engrave the internal area of a shape. | ||
| + | - Cut Mode will cut on the lines. | ||
| + | - Unsure of other modes. | ||
| + | - Need to Set Knife Origin in the application, | ||
| + | - Click Download, Delete All (clear queue), Download Current | ||
| + | |||
| + | Laser: | ||
| + | - Position laser, then material | ||
| + | - Press enter, then enter again, SET LOGIC ORG (ORIGIN). | ||
| + | - Do test button to trace outline of cut. | ||
| + | - Press Z button to start changing height, then up and down. Press Z again to exit height mode. | ||
| + | - Use little wooden tool to ensure bed height is correct | ||
| + | - Never push Datum in Z mode. There is no safety switch in Z mode, so it would keep lifting the bed and crash it in to the laser. | ||
| + | - ESC is your friend | ||
| + | - Wait 10 seconds for extractor to finish extracting after finishing cutting. | ||
