I'm getting an infrequent, intermittent z axis problem.
The first time this problem occurred, I was stopping a file by using the 'S' key, and the z axis bound up and I lost my z zero point. I assumed there was something mechanical causing the problem, so I tried putting the z axis through it's paces by using the keyboard commands. No problem moving up or down. I double checked all of the electrical connectors and they all seemed OK. Went through the rest of the day with no problems.
The next day, yesterday, the same exact sequence. I needed to stop a file, hit the 'S' key, the axis bound up, etc., etc.
Could there be something awry inside the ball screw? I've read the thread concerning Z axis creep, but I believe those problems were with Z axes that were shipped with a problem. I've had this machine for nearly two years.
