Why it happens?
This is caused when the feet aren't all level.
Manufactured pieces always have tolerances (a small range of expected sizes). Minimal wobbling could be inside the normal tolerances and doesn't mean there's a defect. But there are still solutions for it.
How to fix it
Any of the following steps may fix the wobbling. Likely, you don't need to apply all fixes.
- First of all, make sure your tenting legs are set up correctly. Follow the instructions in this video.
- Try out the keyboard on different tables and in different orientations first.
An imperfection as small as 0.1mm can cause a slight wobbling, so sometimes, the curvature of tables can cause wobbling. - Check that the screws at the bottom of the keyboard are not loose.
Be careful not to tighten them too much either, just enough that they are completely screwed in. Then check for wobbling again. - Applying downward pressure on the Defy while tented on the wobbling position. You can see an example of this in this video here (shows the Raise, but the same applies to the Defy):
You can push moderately hard since the Tenting legs are robust (don't apply your body weight, just a fraction of it). The goal is to make all pieces and bolts fall into place. Our manufacturing technicians use this method when necessary. - Change some of the little U-shaped plastic selectors that are fitted between the two rods of the legs. If you swap them around, due to the tiny differences between them, inside the manufacturing tolerances, you may find a combination that reduces wobbling to a minimum.
- Use a big mousepad under your keyboard and mouse. This will cushion the Defy and will remove the wobbling. It works surprisingly well.
