I finish a CNC to making PCB, fully automated, you send PCB gerber file via internet, you paid and the machine start produce it. Microscope to calibrate and control. Scanner to have crontrol of quality. Unique drill hole size, no auto-tool changer, all made by part available in Bolivia and common part.
Mean: CNC mecanical part done, electronic panel (with ESP32 controler to have full check end-stop), local software as little client, website, full node to process the gerber and manage all CNC connected.
In Bolivia now, any body can import, then have CNC 100% mechanical it’s optimal, not consume chemical, it’s more eco-freindly, no liquid management. Cut down the PCB to fall into the hand of shipment agent.
