Hello,
yes, it will work with the DeWalt 611, that I already have.
You can find all that you need here:
Phil Johnson Build - #14 (Eccentric nut)
A mod to make z-azix more stiff and easier to adjust (Z Axis mod)
A 30 minute x-axis mod to reduce chatter (X Axis stiffening)
Pretty easy, it requires an hour pretty much. If you want to improve the GT-2 Pulley, you can check my article here GT-2 Pulley upgrade though there are also some other valid mod to make (for sure some of them better than mine)
