I have a 24x48 Standard machine. Had it up and running since around August. I hear a pretty loud pop when my Z axis is moving towards the table. It is at the same spot every time. I thought it was the plastic cable tray for Z binding, but upon further looking and listening, it appears to be coming from the Z axis. I don't hear it going up excpet maybe a slight bump like whatever it is getting loaded. The "pop" only happens when traveling towards the table. It sorta sounds like something is loaded and released at that particular point. I can't see anything doing that. Of course I can't see behind the router mount/carriage assembly or inside it. It doesn't seem to affect the cutting, but I think it is above where I do all my cutting. Any ideas? I'm afraid not to address it in fear that something may eventually snap for good! If I can remember,I'll take a video of it happening.
Thanks,
Tony
