+ | ==== Work Piece Setup and Calibration ==== | ||
+ | |||
+ | === Work Piece Bracing === | ||
+ | |||
+ | * Open the laser cabinet | ||
+ | * Insert your work piece onto the honeycomb bed | ||
+ | * Ensure that your work piece is flat on the surface. | ||
+ | * If your piece is not entirely flat, you may consider applying magnets to the workpiece to brace, lift, or flatten it. __**Do NOT place magnets in the laser path.**__ | ||
+ | |||
+ | {{ : | ||
+ | |||
+ | //Use magnets and spacers as needed to align, flatten, or shim your workpiece.// | ||
+ | |||
+ | === Laser Focus Calibration === | ||
+ | |||
+ | The laser should be focused to your workpiece on every cut. | ||
+ | |||
+ | * Grab the focus tool from it's very special home on the top, right surface of the laser. | ||
+ | * Lower the Z stage until there is a large enough gap between your work piece and the focus plunger (on the laser head) for the focus tool to fit in between. | ||
+ | * Press Z > DOWN-ARROW to lower the stage from the control panel | ||
+ | * Slide the focus tool between your work piece and the focus plunger. | ||
+ | * Ensure that only the plunger will make contact with the block as we anticipate the Z stage moving upwards. | ||
+ | * While still in the Z menu, press " | ||
+ | * After the Z stage stops moving, remove the focus tool block by carefully sliding it out from above your work piece. | ||
+ | |||
+ | {{ : | ||
+ | |||
+ | //As with all tools, always return the Focus Tool to its home!// | ||
+ | |||
+ | (need focusing procedure support imagery) | ||
+ | |||
+ | === Go Time === | ||
+ | |||
+ | It's almost time to cut! | ||
+ | |||
+ | * Move the laser to the origin of your cut. | ||
+ | * Hopefully, you set a reasonable origin when prepping your file in the CAM software. | ||
+ | * Place your left hand pointer finger near the " | ||
+ | * You will press " | ||
+ | * Press " | ||
+ | * Now you're ready. | ||
