move buffer size, in number of moves
note that each move takes a fair chunk of ram (69 bytes as of this writing) so don't make the buffer too big - a bigger serial readbuffer may help more than increasing this unless your gcodes are more than 70 characters long on average.
however, a larger movebuffer will probably help with lots of short consecutive moves, as each move takes a bunch of math (hence time) to set up so a longer buffer allows more of the math to be done during preceding longer moves
