* The etching tank took more than ten minutes to heat.
* Once in the etching tank you should see a colour change (the non-resist area will turn an orangey colour) within a couple of minutes--these are not the colour change you are looking for. Take my word for it. You can confirm this by testing the complete conductivity of the board with a multimeter.
* After multiple stops and starts it took maybe 15-20 minutes to etch the board. Once the copper finally starts to disappear it is quite rapid however. Keep an eye on it and maybe re-orientate the board to ensure even coverage.
