Laser Control Panel

After upgrading my China laser SH-K40 IV to OpenSource version LAOSLaser (http://www.laoslaser.org), I had to create a brand new panel to house the control PCB with LCD, utilizing the LAOS I2C panel V0.4. To give this model a professional touch, I included a high-intensity red LED for a laser indicator and a manual trigger button that fits snugly into the original panel window without requiring any modifications. Designing the new panel from scratch involved some careful planning to ensure a precise fit within my laser housing. Using computer-aided design tools, I created a digital layout of the panel that would perfectly align with my laser's dimensions. The design also took into consideration the need for additional ventilation to keep the system running at its optimal temperature. The finished product features four carefully positioned PCB spacers (M3 10mm) designed to provide secure support to the control board. To achieve a professional look, I used high-quality white acrylic that provides excellent durability and light transparency. This material also helps minimize heat build-up around the components. For users who want additional protection for their LCD display, I provided detailed instructions on how to create a clear acrylic overlay with an enlarged window (+0.3mm) to compensate for the laser thickness (approx. 0.14mm). With this modification, the screen remains easily readable while providing optimal laser accuracy and precision. For the manual trigger button, simply press the PCB in order to switch on/off the laser system and adjust various parameters such as laser power and pulse duration through LAOS I2C panel. A red LED is used as a safety indicator for safe usage of the machine. Follow these simple steps: To assemble this control panel, start by identifying the position where the 4 spacers (M3 10mm) will be fixed to secure the PCB board using M3 screws. Next, use laser cutter or a sharp utility knife and some care, cut out the white acrylic parts indicated on the layer "Helper", which show the panel window and its exact position on your laser housing. This design is crucial in fitting the components properly within their intended spaces without causing damage or affecting system functionality. Ensure you are aware of proper PCB spacer handling techniques before assembly to avoid damaging these small but critical parts that support all circuit boards and electrical components. When working with any new components, remember to test them thoroughly prior to combining them for use as part of the control system. To get an idea about where the PCB spacers go look at the Layer named "Cut", where it is labeled: position. Place the acrylic layer (layer 'Helper') on a smooth work surface, using tweezers, take each M3 screw and fit through PCB holes into corresponding holes in spacers then put the spacer over an engraved spot which holds indicator switch button for your convenience of pressing manually laser off when desired. A red laser diode serves as an LED with adjustable brightness settable to meet user preferences from simple use on desktop all way to mobile operations or more advanced automation settings that need high level controls. When the new PCB assembly has been finished it is a good idea, clean each and every connection of the components before they start the installation process. Finally for extra protection add your LAOS I2C panel (V0.4) LCD on layer named "Engrave".
