Move the switches or the trigger plates or both will be the best option.

The home position should be about 1" to 2" from the end of travel its not critical, you then set the work area with the soft limits plus and minis from the home position.

you can reverse the direction in homing and limits but you will have to reverse your softlimits too.

If you press MDI and type in G01 G91 X1. F10. and press return the table should move to the left

Then type Y1. and enter and the table should move to the front.

If you are in MM then X25. F100 may be better

Do you have homing switches on your machine?

Is the material in the CAD the same size as the material on the machine?

If the answers are yes then click home all.

Move the centre of the spindle over the back right corner of the material and click 'Zero X' then ' Zero Y'

Touch tool on top of material and click 'Zero Z'

Click Regen Toolpath

The problem is the way you have drawn the part in 360, the XYZ is in the opposite direction to the datum on your machine.

Your cad datum is front left of part.  Machines tend to be top right.

Most machine tools home with the table left front and up for the XYZ so you draw in your cad to the left of the X (Red arrow) front of the Y (Green arrow) and Z is top of work on a mill and in most cases bed of machine on a router.

Do you have a tool changer or a tool setter?
