This was the first time I have updated and had it take more than a minute or two. Today, I updated and my pendant stop working all together. The Z DRO stopped responding for a while. I rebooted at least 5 times... I got messages that I couldn't do something as the machine was in motion... but it wasn't moving. After one reboot I kept getting a popup to load the tool, but no program was even loaded. After all of that, and a bunch of rebooting, my pendant is now working again. The DRO is working now as well. Maybe it was just bad luck today. Instead of a couple of minutes, it was about 2 hours for the upgrade to 2.2.4 from start to things settling down. Really odd. In the end, I was able to run a conversational program for some engraving using a single stroke font.
