Did anyone at Metalab try cutting PCBs on our vinyl cutter?

I tried something similar: I used vinyl as a mask for etching. It worked (I even used this method for a QSOP-chip breakout board), but the quality was limited. The thickness of the traces was varying (+/- 0.3mm, maybe more) and I had to do a lot of repairing work with a precision knife. You might get better results if you only use curves instead of straight lines with quick turns, but as it's an accuracy problem I think it's unavoidable. Here are some photos: https://www.dropbox.com/sh/dmefmfn307do5cl/B9L2-fqkIT/100_0759.JPG https://www.dropbox.com/sh/dmefmfn307do5cl/rY5lPUlmkm/100_0799.JPG PS: As someone mentioned before: If you want to do that, get an other knife. Also make some photos of the results, I'd love to see them. -powertomato
