Hi All.

I am in the early stages of designing a multi-axis machine for home use, and am interested in the construction details of the gantry beam of AXYZ's Z series and Pacer series machines. Are there any owners of said machines out there who would be willing to take a few close-up photographs of the beam of their machine, preferably with the end plate removed to show the internal profile? It appears that the Z machines use a custom aluminium extrusion as the beam, whilst the Pacer machines have the option of a steel beam that appears to be a length of RHS.

At this stage I am simply trying to understand the rationale behind the design of these beams - especially the steel one used in the Pacer, Trident, and Infinite series machines. From reading brochures and watching videos, the bearing profile rail appears to be mounted to a separate strip that is then screwed to the RHS, which seems like a strange design decision.

Thank you for any replies.
