Hey all! I am a very happy customer with my S1 20W. I have a massive (for me order) of keychains and I'm wondering if it's worth upgrading to the F1U at this point. This job could pay off half the F1U.

I made these "coin" keychains from 3mm basswood. Someone liked them so much that they wanted me to make 4,500 of them for an event. That's a lot of engraving, then cutting, then flipping them and engraving the backside.

I was thinking of cutting them on the S1 and using the F1U conveyor to engrave them to spread the workload.

Questions:

1. Can the F1U detect these blank coins, recognize the keychain hole as the top of the coin and engrave the coin properly?
2. Would the F1U be significantly faster for this engraving than the S1?
3. Similarly, I could save myself the cutting step and buy these blanks on Amazon and engrave them. I'd have the same issue as above. I would need the F1U to recognize the top of the keychain blank and engrave the image appropriately. Can the F1U do that consistently?

Thanks for any help you all can provide!
