newbie question xyz and tool movement direction

[LockTech]

what is common or is everyone diff as far as each axis and which way the tool moves for positive or negative


example.. currently x-axis moves tool in the direction of arrows on keybord and y-axis is opposite and moves the table in direction of arrows.

Picture the tool moving opposed to the table. The "Cartesian coordinate system" is used. http://en.wikipedia.org/wiki/Cartesi...rdinate_system This is standard for most machines.

Hope this helps.
