You can change the soft limits with parameter 1320 and 1321. Move the mill to the farthest location you want to travel and then look at the axis "Machine" location in the all POS view. Take that number plus whatever margin and put that in the stored stroke limit.
The value of stored stroke is .001 mm or .0001 inch
Soft limits use software to protect your CNC machine from movements that exceeds a set position. No hardware is required when using soft limits since the software uses the encoder counts. It is important that the machine is correctly homed since soft limits use the current position to determine if the axis is allowed to travel within the minimum and maximum defined area. This area is also known as the Soft Max and Soft Min.
