I bought a brush type rotary not knowing how hard it is/impossible to make work with my 2019 haas mill, I know a converter box exists and Haas still sells them, but they are telling it's 100 percent incompatible and will not work.

I bought the rotary because the company was really the only company willing to prove to me that it was in good working order by doing a backlash test on video for me to see. I honestly was not aware of how incompatible it was going to be with my machine.

Anyways I know it isn't going to be easy, but is it possible?

Thank you,
Dylan
