A couple of beginner questions... Profile sizes and cutting area size.

The axes are defined with you standing how you would actually use the machine.

Side to side is X. X+ is the cutter moving to the right. Towards you and away from you is Y. Y+ is the cutter moving away from you. Up and down is Z. Z+ is cutter moving up.

This is a simple convention from drawing. The same as graphs. It is used in virtually all drawing/CAD/machines.

Unfortunately a lot of hobbyists can't understand the convention and insist on called the axis across the gantry Y or some other variation.

For instance on my machine:
Working area 1300x675mm.
Gantry is the long axis.
X runs across the gantry, 1300mm.

X is not necessarily the longest axis. X is not necessarily the lowest/bottom axis. E.g. X is on top of Y in my machine.
