Is there a simple way to set mining turtles to exclude valuable ores? I've got a TiCo pick with Luck (IIRC), and I'd just as soon use that for any diamonds, draconium, rubies, etc., instead of letting the turtle get the default drops.
Does this require Silk Touch to get ore blocks, and use a mining program to exclude specific items?
I've used this quarry program from AustinKK. It has the ability to ignore/not mine blocks based on what it starts with in its inventory. I you could use this to mine everything except the blocks you want to silk touch. Normal setup is to ignore stone, dirt & gravel.
