Stalling in X Axis

Z head stalling on the X axis.

If your Z-Head stops suddenly, yet still trying move along the X-Axis, there are several things to consider;

1) Check the motor pinion setting.

The motor pinion engagement with the racks needs to be set so that the surfaces touch correctly. If the engagement is too light, then the pinion rotation will skip over the rack teeth. If the engagement is too tight, then the pinion rotation will bind to the rack teeth causing them to jam. Both scenarios will cause the Z-Head to stall.

The servicing procedure identified in our website support page maintenance section covers the process of setting the pinions. See the video link from 5:15 onwards;

2) Check the wheel setting.

Like found with the motor pinions, the setting of the Z-Head wheels will effect the performance of the X-Axis movement. Again, if set too tightly, then there will be excessive resistance to the Z-Head movement. If the wheels are set too lightly then the Z-Head will become too loose to be able to operate correctly. Both of these scenarios will contribute, in part, to stalling along the X-Axis.

The servicing video for the X-Axis identifies this;

3) Check both points 1) and 2) together, if the X-Axis stalling is severe.

 

4) Should you find that there is still an issue with X-Axis stalling, having followed the relevant points above, there is one more set of checks to undertake which will help us to resolve your issue.

a) Turn-off the power to the Smartbench. Then, using your hands, push the Z-Head along the whole length of the Upper Beam. Please report your findings along with a video, to us via the Support Ticket system.

b) With the power turned on to the Smartbench. Using your hands, apply in region of 10kg to 15kg of pressure to the Z-Head and try to push against it, along the line of the X-Axis. If there is any movement, please report your observations along with a video. to us via the Support Ticket system
