  • Z Axis Failure


    I've asked in another area of the forum, but have gotten no response. The Z Axis on my Stinger 1 has stopped and its making a "thud" noise after moving about 3/4" from the top of it's travel. I removed the motor and plate covering it to determine its in the ball screw/rack & pinion drive, or whatever it's called is the problem. Anyone else experienced this problem?

    No- just a motor failure after many years of faithful service.

      is there something stuck in rack an pinion? A bolt or nut backed out somewhere, (in the rack)stopping travel? Just guessing. Not familiar with stinger

        When you removed the motor from the system does the problem go away? I’m guessing not based on your reports.

          Nothing stuck, loose, or backed out. I removed the Z axis motor, and the shaft will still not turn. I'm assuming there's a bearing or collar failure inside the bearing housing, but I don't know how it comes apart. Does Camaster have field service technicians?

            Very seldom does a motor go bad. Drivers can fail, and wiring can go bad. A loose cable from pc to controller can drive you crazy. You can swap motors and verify, but I doubt it is the issue. They will work with you over the phone and log onto your pc if you bought it new from camaster. If you bought it used, you can pay wincnc by the hour to help online. As for getting a tech out, I think they will, but airfare and a tech are not cheap.

              Do you mean the stepper motor will not turn or that the ball screw shaft doesn’t turn?

                  If you can't turn the ball screw with the motor off of it, then it's just a mechanical issue. Pull the ball screw off and make sure the z slide assembly works smoothly, as far as the bearings go. Don't let it come off of the rails all the way, as little ball bearings could be ejected out of the bearings.

                    I was able to get everything apart and found the ball nut to be the cause of failure. I'll be reaching out to Camaster first thing Tuesday (12/26) morning and get what I need to get up and running again.

                      Use the online tech support query today to get in the queue.

                      good job digging in to the problem.
