Dotted and colour changes are nothing to worry about as you probably suspected.
Table running left, forward and up will mean that the cutter is fully positive in all directions, so on Homing and limits page you will need to have a Home Off value set for X and Y axis. The value of that will be the amount of travel you have.
You will then set X and Y min as Zero
X and Y Max as whatever your travel is
Z Min as the amount of Z travel but as a negative
Z Max as zero.
Doing that should make things work for you, what will happen is when you home the machine coords will be set to your Home Off values on X and Y and Zero on Z, this will let Mach know that you are at full extent of travel in the positive direction.
You will also need to set up a slow zone for each axis, this will be dependant on your axis speed and acceleration so you will just have to mess around to find what works for you. How to do that is set a slow zone of say 20mm or 0.75 inch (depending if you are metric or imperial setup) Make sure you have softlimits turned on then jog away and then back at full rapid and see if the axis slows and stops just before it hits the limits, if it does then fine, if its too fa away when it starts to slow then reduce the slow zone, if it hits the limits increase the slow zone.
