I'm not sure what context you're saying you have for the XHC. I have he XHC-HB04 on LinuxCNC RT on the Linux RT kernel.
It's a VERY smooth response, but partly because my machine is very fast. There is, however, a case for time delay if you select jogmode=normal and not =vnormal on a slower machine, or with greater scale on the handwheel. Depends on the jogwheel speed vs the machine's acceleration and max velocity. IF you set the wheel to its highest speed and spin it fast, you might command a router to move 50" in one quick twist of the hand that will take the machine 5 sec to execute. This rarely comes up with me. My machine is very fast and you have to spin the wheel unnaturally aggressively at top speed to get ahead of it, and it's not possible to get ahead by more than like 1 sec. It cannot always keep the commanded position AND stop immediately when the handwheel stops. That's logically impossible. If you don't like that, you can select jogmode=vnormal and it will always stop when the handwheel stops. However, you lose sync with the wheel. e.g. quickly spin the wheel +2 turns forward and it may only register 1.5 turns before the wheel being stopped means the machine stops moving. Then turn back -2 turns slowly and the machine is -0.5 turns worth of motion from where it started, even though the handwheel is where it started. I don't like this functionality myself. And even that vnormal mode only means the gantry begins decelerating when you stop turning the handwheel. If the machine takes 0.75 sec to come to stop from jog speed, it will not come to a stop until 0.75 sec after you stop the handwheel. I recommend you reduce scale if you don't like it. e.g. if you would never turn more than 2 turns/sec on that handwheel, and your machine's got a quick acceleration and 5 inches/sec jog speed, the scale should be ~2.5 in/turn so you never outrun it. With acceleration being significant, there's no definitive answer.
