i will be doing the same thing over the next couple of months. i have two km3p's with one still running. i am half way done with a second attempt on a hurco sm1 that had the original dc servo's and rutex drives, and now will have ac servo's and drives from teco with a mitsubishi vfd. i had reliability problems with the rutex products, so it is time to switch. i will post some pictures next week of the mill. if all goes well the other two hurcos will follow.
