Note that this is (in direct form) only suitable for the projector in the Mars 4 DLP. If you have other boards check out the repository for the Anycubic Photon Ultra, or get in touch for modifications needed. The designs in this repository then allow you to project arbitrary 2560x1440 images with UV light on a surface. The native projected pixel size is 50μm , making PCB fabrication an interesting application. All you would need is a bit of glue code to convert the Gerber files to a rasterised image and then you could easily use the existing 3D printer frame to expose PCB boards. Since you have all the files and access to the code, you can easily tune it to whatever production needs you have. The UV projector of the Elegoo Mars 4 DLP is developed and produced by Anhua (D63ZS50B), and seems to be this variety. Under the hood it uses the Texas Instruments DLP300s or DLP301s digital micromirror array. [!NOTE] While PCB fabrication is the most straightforward application for this board, this is actually developed as part of an effort towards an open hardware photolithography system. Check out the openMLA organisation for more info. If you have a projector using the DLPC1438 that uses the parallel video interface (rather than SPI) then you can check out the PCB design and implementation for the Anycubic Photon Ultra projector. 🚀 At a glance","default_branch":null,"files":null,"tree":[],"storefront":"/r/openMLA","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/openMLA/elegoo-mars-4-dlp-controller/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
