But as i try to configure linuxcnc for my current set up, the settings i want in linuxcnc should be
200 Motor Steps Per Revolution
2 Driver Microstepping..
Do i need to change the driver steppers dip switch to the settings i want in linuxcnc so they both match??

If you have different microstep ratios in the driver and in LinuxCNC then your axes will move twice as far (or half as far) as they should.
It's fairly easy to work out if that is the case, it isn't a subtle error.

meaning steps/mm or steps/inch
THIS is PRINTED almost at the bottom of the Stepconfwizard
so you can controll this as you caculate your Hardware and softwarestepping
THE wizards calculate also for you but only to check
200Steps/Motor 4Microsteps -> 800steps/rev
pitch Ballscrew 2005/1605 -> 5mm
so you got 800/5 -> SCALE 160Steps/mm

some of this I just do not understand and i apologize for that...When I read the manual it does not help me all the time, but i always try it first...
In my case do the step drivers dip pin need to be changed or does the linuxcnc only allow what you put in the config...
example, my step driver are set at 4 micor steps and 800 steps/rev..
but in linuxcnc in the config i input 200 microstep and 2 microstepping...
does linuxcnc only allow the 200/2 or do the mix match of numbers cause issues at the table,
thanks for the help in advance,

That is wrong, you need to set the microstepping the same as in your drives, so 4.
Linuxcnc allows any numbers there, but it is easier for you to understand if you stick with the normal values like
motor 200 step/rev
microstepping 4
pulley/teeth 1 and 1 if you have direct drive ballscrews
and 5mm if you are using the usual 1605 or 2005 screws.
You can also manually edit the ini file and enter 160 for scale. You get the same result as PL7i92 pointed out.
