UGS freezing computer

So I finally got a dustshoe and are using it with my shopvac. The first job i did worked just fine.

But after that, while setting the zero for my second job my computer froze. At this point this vaccum wasn’t on. And ugs didn’t say “not responding” or something like that.

I rebooted my laptop with the power button and repeated this process about 5 times before I finally managed to get far enough to start inute in it it froze again.

Any ideas??

Edit. I’m using an arduino uno with a grbl shield and drv8895(orsomething) drivers. I have ran the machine quite a bit before with out any problems what so ever…
