Hi Thom,
really really good addition fpr making circuit boards.
I made one about three weeks ago about 60x80mm with regular 35um copper. I 'etched' to a depth of only 50um and got
perfect isolation across the board and that was with TSSOP ICs, 0.3mm between the pads. Never been able to get such fine
detail until I started using Autoleveller.
