I'm sorry, I've seen this to many times. Yes, it would be nice to put a magic spell on a Fadal and make it capable of moving faster.
I'm sure it's better than many std controls on low price machines, but you can't change the Acc/Dec of a machine with a control. If you increase the feeds it will still over shoot into a corner because the machine can't keep up with the control.
I'm sure it does improve a Fadal because the early ones didn't have look-a-head, but it's still a .1-.2 G machine. Machines like DMG, Makino, Huron, Mikron, etc. are .7 to 2G ACC/DEC. The only way to increase the feed to what he claims without making crappy parts is a combination of the control, structure, drives, screws, spindle speed.
Give me a DMG or a Makino and I would outproduce a Fadal with any control by 8 fold. I've seen it over and over.....
