On a typical “Cartesian” machine, each actuator (a motor and a linear rail, named alpha, beta, gamma) corresponds to an axis (like X, Y, and Z).
However, on other machines, the position in Cartesian space (X, Y, Z) must be converted, using math, into a more complex position for the actuators.
This is the case, for example, of linear delta (often just called “delta”) machines.
Currently, Smoothieware supports the following arm/motion solutions:
