Question about Open Builds Interface and Xtension limit switches.

I got my Lead 1010 up and running using a Black Box and the new Open Build's Interface.
jogging to trigger all 3 limit switches shows the red LED's on the switches and
will show X Y Z blinking on the Interface screen. However it does not stop movement
nor is there any beeping alarm from the Interface

Is there any chance that a warning beep can be added to the
Interface when triggering a Limit switch? I almost crushed a couple limit switches today.

Also jogging to trigger all 3 limit switches and setting to Zero and then turning off Black Box and
turning it back ON shows on my machine X-35.66 Y- 10.55 Z - 9.54

So why is it not staying at Zero? I haven't moved anything. Just turned it back on.

 

Can't. Computer is in my house and the CNC is in the shop.
Can I just bring the power supply and Black Box in and plug it into my PC?

 

Thanks
