Just got done reading an article in the Digital machinist magazine I have been getting and noticed a small ad at the bottom of the page touting a true closed loop board that uses Gecko drives somehow. Checked their website and it has a gecko board that uses some other board and allows closed loop. IS this true and is anyone here using this system on their machine?

It says in the ad that the system will maintain dro control even when the geckos are powered down. Sounds real cool and the board is only about $100.00 . Do you need to use the other board or can you just use this with an existing breakout board like my C11g? Any and all information on this would be most appreciated...peace
