What is the purpose of DDA.cpp?

[jazbaatbadalgaye]

From my understanding it generates trajectory at every time step. Do I have it correct?

[dc42]

@jazbaatbadalgaye a DDA object describes the move as a whole and generates the step pulses. The associated DriveMovement objects describe the individual sets of motors that are moving.

[jazbaatbadalgaye]

@dc42 "Set up a raw (unmapped) motor move" What does raw/unmapped exactly mean?

[dc42]

@jazbaatbadalgaye it means that the move addresses a motor set directly, instead of being mapped through the current kinematics. For example, a direct motor move on a delta or CoreXY machine.

[jazbaatbadalgaye]

@dc42 Gotcha. So unmapped motor move is basically a move that could be mapped to either delta or CoreXY printer hence the name unmapped?

[jazbaatbadalgaye]

@dc42 Can you please explain the purpose of the endpoint array? And by endpoint do we mean the end coordinates of a move?

int32_t endPoint[MaxAxesPlusExtruders];
