Hate to bump a two year old thread, but I just started a new job and we have a 1999 Partner and it's having Y axis issues. Could you go into more detail about where to find the encoder and homing switches? I have the way covers removed and the lead screw turns freely. I switched the cabling on the drives between X and Y and it still trips out on Y, so it's not the driver.
