🍪 Crumbs - Collection of my DIY Electronic Module

simple direct step to generate quite accurate 2 layer PCB with only paper, pcb board, uv laser and free software

- make sure to add corner dot marker in bottom and front layer, so bottom layer will correclty flipped during flatcam process - generate gerber from eda software - import it into flatcam, add buffer 0.06 to all copper layer (front and bottom) - do isolation routing to all copper layer, make sure to flip for bottom layer before do isolation routing - choose pre-processor grbl laser - generate nc file to use for uv routing - open laser grbl, choose center corner marker to marking…
