Dreaming on this, the next logical check is with power off, with an ohmmeter, to verify that from my driver box, coils aren't swapped by the wiring. A works, Y works, X doesn't and Z doesn't and those 2 are noisy as all get out. Inverting the drive signals has no effect. So obviously its the motor coils are being mix-n-matched between my drivers and the motors. An ohmmeter reading will tell that truth. These are the same identically constructed cables the drove the old HF flawlessly but at the limited speeds caused by software stepping. Z did work, driven by the oem box. X has never worked. Thats trying to tell me the oem cables are not wired alike. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
