Hi all. I apologize if this has been posted already, but I recently got my second machine (my first, which I got about 16 months ago, is a AR4Pro+, which I still have, and I am using it as a secondary machine (rotary axis, digital joints using Tailmaker software, diamond drag work, etc)) which is a AR8Pro+. One difference that I noticed with the controller is that it does a "3....2.....1...." countdown before the spindle powers up (a nice safety feature), and my AR4Pro doesn't do this.
I'm guessing it is a fairly recent firmware update, but I don't recall seeing anything about it, and I'm curious if there were any other changes that would merit updating the firmware on my older machine (the AR4Pro). I am hesitant to do it for a minor update, since I believe firmly in Murphy's Law and I'm concerned that I might "brick" my controller for no real gain (the countdown is nice, but I have lived without it for the past 16 months, so......).
