I think this would be more for a V-two, but let me share my ideas.
There were already a few ideas regarding Camera or Pick'n'Place Attachments. But what if everyone can make his own attachments?
One would need a well documented hardware interface (mechanically and electrically) to build his own head.
Mechanics should be easy, just release the mechanical interface dimensions (place for the magnets, dimensions to the gear and the pogo-pins). Electrically I thing we need some kind of universal Interface... A good powersource (12V 30-40W), a usb plug and maybe a serial interface like I2C.
Beside of the camera and PnP attachment I'm thinking of
pen holder, simple but useful... to put text or markings to the board. need a pen with a flexible tip commands to raise and lower it where it should write. Could be usefull to drill vias before applying conductive ink and then fill in advance.
a drill head with suction. I didn't do the math until now but I think for drilling vias and pads for through hole components drills up to 1.5mm should cover the most parts. I think a 30W motor should do the job.
an modified ink dispenser which is capable of filling vias. You should add a collision switch to make it possible to drive the tip into the via holes without risking a broken dispenser needle. This should be possible with the V-One already.
a parking position with a cap. One should be able to put in the Dispenser with the cap attached. It is then removed by the printer itself and reatached after the work is done. make another grove next to the others for holding the cap (electromagnet?). Evertime i switch the attachment I'm frightened that i crush the tip somewhere.
you can find cheap "PCB Drill DIY Kits" at Aliexpress. This one looks nice.
Pls let me know what you think
