6x6 Stewart (Parallel Kinematic Machine Tool)

Does it work?

I would only expect you to have control of 3 actuators with that config, but does it actually boot?

If it boots you can look in Machine-Show HAL Config and work out what the other stepgen pins are called.

Then you need to copy the INI-file [AXIS_X] sections for [AXIS_A] and so-on and copy the HAL file sections for the extra stepgens.
