What direction should axis be on a prusa i3 rework

All in the title, what directions should axes be on a Prusa i3 Rework ?

Mine is:

X: 0 to the right
Y: 0 to the rear


My Y axis motor is at the rear to, to the fron I have the two Z motors, and the extruder is to the front (just to be shure we have the same front)

Is this the correct way ? Looks like the axis on Repetier host are in this way, but my prints are mirrored.

EDIT: This is how my printer looks: [imgur.com]

0,0 should be front left of the print bed I believe.

You should be able to just reverse the direction in your firmware.

Think I have same i3 as you Korri. First power on today
I have end stops
X right side
Y rear
Z bottom down

Managed to get action using Auto Home from LED panel menu
Step by step I got it fine to X and Y end stop
But after that it started movin Z upwards .....
So I'm not sure now i Z end stop shall be up or down.
Or if I have Z motors wired to go wrong direction ...
Having a hard time just to get the simple information on what end the stop switches should be in
Not loaded any FW or Arduino stuff yet ....

I had this issue,
I had the Y Axis going the wrong way, when I set it up I had the bed moving in the direction of the arrows in the host, it should be the extruder moves relative to the bed,
You can have 0'0 where you like, I find having the bed out font is easier, I cover mine during warm up to speed things up a bit, it's easy to flip it with a true or false statement in the firmware, it usually gives a hint in the firmware but you may have the belt anchored differently.
Hope this helps.

Yes, you are right Paul. You can choose as you like if you adjust statement in FW.
Anyway I found out that
X left
Y rear
Z bottom
is what is compatilble to the Auto home function in LED Smart panel
So I'll move my X endstop to left
I also was incompatible with motion of Y motor (for Smart panel)
So I turn connector of that motor 180 degrees to get that fixed.
Now I can use Smart panel Auto home and the other functions there in case I need to trouble shoot in the future.
But once you get calibrated good it does not really matter ....
