Travel limits after homing help?

What do these numbers represent on a Delta and how do I determine them?

Do they represent the motion across the bed or the slider position on the towers? Or something else?

Here's what I have on my Marlin config.h but I have no idea if it's right.

#define X_MAX_POS 102
#define X_MIN_POS -100
#define Y_MAX_POS 98
#define Y_MIN_POS -94


thanks!

Ita the limt the hot end can move after homing
Z Should be the printers height, from nozzle to bed.
X positive number is how far from the center to the left ot can move.
X negitive number is how far from center to the right it can move.

If your print bed is 200mm end to end.
You would have
X 100
x -100
Y 100
Y -100

Same of the bed was 180 edge to edge 90 and -90.

Almost forgot.
You dont have to have it be the max that your bed is.
You might have a 220mm diameter bed but there could be screws holding the bed down. So you might wanna limit it to 210mm (105 radius) to not hit the screws
