Beginner wanting to learn PCB Milling

You have to mask off where you don't want the solder mask to be applied....I believe there are some hobby spray on options....before long..you'll find it cheaper to prototype the layout then have some make the PCB for you.

Hello. I agree with Viper. The principal benefit from milling your own PCBs is speed and cost of using the already existing CNC machine. However, the benefit curve quickly turns toward outsourcing when you get into more complex areas like having to soldermask, silkscreen or multilayer a PCB. But half the fun is trying to condense your circuit into a single-sided layout and soldering an MLP chip without a mask.
