A1 First layer test

Hello everyone, this is a first-layer test model for A1, used to test dynamic traffic and print boards. It can quickly locate the problem and can be used after plugging. Feel free to download it. It wasn't easy to create, so if you like it, please give it a thumbs up. Thank you!Boost MeYour support is my biggest motivation to keep updating!After our second update, the model no longer overlaps with the lines of the dynamic flow calibration, so please print with confidence!
