Hi

I work as a research engineer developing a machine that uses 5 axis kinematics the same as a "swivel head" type setup (see video below for an example, though not our machine) and would like to use LinuxCNC to drive it, as it has a great feature set and reputation.



I note that LinuxCNC features a 5 axis kinematics module and that the documentation specifically references swivel table type 5 axis. Please can you advise if the same kinematics module will cover the swivel head type setup as illustrated in the video (often referred to as a B/C head), or if not, whether you are aware of a community written set of kinematics that will cover this type?

Regards

Ross

There should be something for any 5 axis setup here, be it included with Linuxcnc or modified by some of the users on this forum.
In any case, from reading here, it is not dificult to modify the kinematics module to fit your needs.
You should wait for someone with more experience in that area to reply.
Regards,
Tom.

Hi Tom

Thanks for the response! I will wait and see if there are any further replies as suggested and have a dig for topics on kinematics modification.

Regards
Ross

In the meantime see if there is something interesting there, one is for modified kinematics and the other for 5 axis kinematics, all only on Linuxcnc site and forum.

the mashine in the video is straight standard so it will fit the standard setup installation

if the mashine is already build you can modifie the kinetics to your need
if you are building it just keep as centerd as posible and you only got the 3 offset parameters
or the 6 if you are not centerd and need generickins

Thank you, as advised it seems the xyzbc kinematics match our needs.

Cheers
RD
