I've been adjusting the steps per value, velocity and acceleration and everything seems ok, but I do get the occasional warning saying I have one or more axis set up to operate beyond 25,000KHz. This does not appear to be an issue as I can rapid without any problem for quite some time, but there does appear to be an issue where the jog velocity drops to maybe one tenth of it's previous speed for no obvious reason. I tried rebooting the computer and checking the relevant settings, but have not been able to find a fix for this.
Any ideas?
