Set soft limits by specifying a corner and the size of a rectangle enclosing the limits
Move the machining head to the lower left corner of the imaginary box enclosing the soft limits desired. From Setup menu, choose Soft Limits and then choose Set by corner and size.
Check "Enable Soft Limits," then enter the maximum travel allowed from the current nozzle position.
For a typical setup, move the machining head as far to the left and bottom as possible (-X, -Y) until it cannot move any further. Then, move the machine 0.25" (6.4 mm) in +X, and 0.25" (6.4 mm) in +Y (so that it is not sitting directly against a hard stop or limit switch).
When moving the machining head to the limits of its travel, it is likely the motors will stall. If the motors are stalled, then when you try to move the machine, the numbers will change on the screen, but the machine will not move. If you open the back of the controller, and look at the two black boxes mounted on the rear door, an LED will indicate a faulted condition. (Depending on the motor amplifiers used, a motor fault might be indicated by a blinking red or yellow light. If it is a non-blinking green light, then the motors are probably not faulted.). If you believe that the motors are stalled, you can do one of the following, depending on your machine: 1) If your motor controller has an automatic reset function, the motors will automatically reset themselves. 2) If your machine is equipped with a motor reset switch, then you can turn and hold the switch for 10 seconds to reset the motors. 3) Shut down Windows, then turn the power off to the controller. Wait 10 seconds, and turn the power back on. This will reset the motors, and you should now be able to move the machine.
When finished, be sure to test the limits by moving the machining head up against the soft limits using the Jog commands. Be careful, because if a mistake was made when setting the limits, the machining head might crash into something. If the motors stall, or if the machine will crash before reaching the limit, then repeat the procedure, but this time enter smaller numbers for the limits.
