I've seen these spikes a lot whilst tuning the servos on my mill. I
think they are a characteristic of FF1 tuning. It is very tempting to

Did you tune your amplifiers to give best response to a command input

It depends how you installed Karmic. If Karmic was a clean install, then
normally it should have installed grub2, if you upgraded from an earlier
version normally grub legacy will be retained. I'll assume it was a

Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day

Only then the driver hardware will latch on the next index, and make the
pin high again, so motion knows index has happened.
