I'm curious about issues with latency (delay) between different kinds of drivers used in one machine. For instance, if I use a different brand of driver on the x-axis compared to the y-axis, and there is a difference in timing, cutting moves would not be accurate. Many drivers are, I'm sure, simple enough that there is no "latency" per se. But if there is a dsp chip in the driver then it seems that there will be some kind of latency for any signal being sent through it. Any comments?
