Any advice for channel building?
As the map I'm using is obscenely flat (I'm built into the side of the one elevation change that occurs on the map, heh) I'm undertaking a large outside moat. When I was digging a single elevation out, everything was fine...The pattern they dug didnt especially matter so long as a middle tile wasn't left after the outter tiles were dug out (3 tiles wide). Once I started doing the channels of depth two, however, problems started to arrise...
Instead of digging in a single direction (Even when one tile wide strips were being used), they'd do the following: The one tile wide strip is horizontal, the miner would arrive and mine the left most piece, then immediately turn and mine out the piece on the right, leaving himself disconnected from the rest of the strip and only the option of channeling directly under himself, dropping him down into the soon to be moat.
So I try to just account for this and build a temporary stairwell on the rightmost part of the last strip...Hah! Fucker then immediately dug the rightmost part of the strip out leaving 15odd tiles left to be dug out and a useless staircase...
Getting tired of trying to finish the fucking moat...Only one miner is active to avoid any undermining and all other mining projects are on hold until it's finished...Living and working space isn't an issue, but I need to expand to the magma and start hunting for ores...
Really wish you could do something as basic as defining a direction to mine in...
