Got a new to me CNC Router. The computer that came with it was obviously not the one running it or there was a piece missing. it was a Win7 machine 64 bit connected via parallel. (and ports and pins were way off.) anyway I added a warp9 and have it moving, for the most part.
This is my first machine with dual motors on Y axis. Anyway I can't get the Y to move together. seems like motors are moving opposite. If I disable Y, A axis moves fine, if I disable A, Y axis moves fine. When both enabled, and Slave A to Y enabled it tries to twist. I checked all the step and Dir pins and they are right (they move fine independantly, but not together. any assistance would be appreciated.
