That seems to be a long going issue with UGS. Some people run it fine with no problems but some have constant issues. Number one thing to check is your computer. Turn off (“Never”) any sleep or power settings that can put your computer to sleep. Go into Device Manager and turn off power settings in your USB devices. These are just a couple of things that might help. As for CNCjs it is very similar to UGS in appearance and operation. The only thing I had to set up was a macro for using the Sienci touch plate but there is a sample on GitHub. IMHO it has a better visualizer than UGS. Other than that they are pretty much the same.
