Customers seek our advice on the difference between the 7-axis and 6-axis HEXAGON arms when using VTube-LASER in tactile mode.
Executive Summary: Choosing a 7-axis arm, despite its higher cost, provides a significantly better user experience. We do not recommend a 6-axis arm for measuring tubes. Both arms are accurate using ball probes. However, the 7-axis arm will provide a significantly better long-term experience along with upgradability.
| Advantages of 7-Axis Arms | Details | ||||||
|---|---|---|---|---|---|---|---|
|
Advantage 1
There is added articulation with a pistol grip.
We have used them both, and would much rather use the 7-axis arm with a grip when measuring with the ball probe. |

Advantage 2
With a 7-axis arm, you can upgrade to an AS-1 scanner later.
With a 6-axis arm, you cannot add an AS-1 scanner later.
