linear motion between switches

hi new this, have built slot mortise create loose tendon mortise in wood , want automate operation

i want use arduino uno , stepper motors automate machine

id to  program machine alternatively move left , right @ steady rate,  on machine there 2 slides limit side side movement used set mortise width add limit switches each side

the idea is  have program run stepper motor in 1 direction @ steady rate until 1 limit switch pressed id change motor direction , run other way unit oppersite switch pressed again change direction act ect.

 id like  program second stepper motor move router wood @ adjustable rate until hits another  limit switch.

i  know how add lead screw t , mechanical business jig need buying electric parts , setting up, i've tried work our myself lost

then possible without need have computer alway attached machine

any highly appreciated feel head around need leg up, thanks

yes, arduino, programmed, handle easily.

i don't know how know steppers here couple of threads basic stepper information (thanks robin2).

running , forth between 2 switches basically, step toward switch, check switch state, step, check, , in until switch reads closed, set direction reverse, step, check other switch, step, check  , on. 

what kind of switches limit switches?
