Leveling 3D printers is a common and sometimes difficult step for beginners when using resin printers, and now AnyCubic has integrated an automatic leveling solution into this printer model to make printing hassle-free and easier for users. The Photon Mono M5s 3D printer is the first resin printer of its kind to feature mechanical sensors to automatically detect and adjust the fit between the print bed and the floating leveling module. This feature largely eliminates the need for manual leveling, which can lead to many printing errors if done incorrectly. This feature not only simplifies the printing process for users, but also greatly increases the success rate of printing models, which is a very positive point. Unlike other resin printers, the Photon Mono M5s does not require manual calibration. The device has a mechanical sensor on its arm that holds the plate, detects how close the plate and the glass are to each other. This feature can make adjustments on its own. The glass actually floats on stiff springs, ensuring a perfect print. All you have to do is screw the plate into the arm and press the print button. This is the first self-leveling resin printer, using a combination of sensors and hidden springs to calculate its level. This is a pretty amazing feature, anyone who has calibrated a resin printer with an Allen wrench and a sheet of paper will appreciate this feature. In order to reduce print failures caused by insufficient resin, the resin detection mode is preset to intelligently detect whether the amount of resin in the vat meets the printing requirements before starting, minimizing printing troubles due to lack of resin. Through multiple tests on the exposure plate connection, mechanical detection module and motor operation status, it quickly identifies and troubleshoots hardware problems, ensuring smooth and non-destructive connections to achieve a flawless print. This printer is mostly assembled, you just need to apply the LED screen protector, screw the container and build plate and get ready to start.
