However, in the delta coordinate system, each axis is oriented vertically, and thus the X and Y axes mechanisms do not move in the same plane. Only the Z tower can be considered in the same plane. But that is not correct either. Recall that it requires movement from all three axes to effect a movement in the X, Y, and Z planes. Thus, you refer to each axis movement as A, B, and C or alpha, beta, and gamma corresponding to the X, Y, and Z towers. You may find some delta literature that refers to these as the A, B, and C towers.
I will remove the veil that obscures the magic in the machine. 37 Chapter 2 Delta Printer Hardware The delta 3D printer design, despite the radically different axes arrangement, uses the same basic hardware as a Cartesian printer. For example, there isn’t anything special about the stepper motors, electronics board,1 or even the hot end. The differences are in how the axes are arranged (all three are vertical), and that the print bed is typically round (older designs use square or rectangular build surfaces) and the frame is typically triangular.
In this case, all three axes are moved at the same time. To move the effector and therefore the hot end up in the Z axis, all three axes are moved the same distance away from the build plate. Similarly, to move the hot end down in the Z axis, all three axes move in the same distance toward the build plate. To move the effector (hot end) to a specific X or Y location at a set Z position, the delta printer uses algorithms to resolve the movement of each axis. While not precisely accurate, but analogous, each axis can be thought of as forming a parallelogram using a pair of right triangles with the axis as the vertical side, an imaginary line from the axis to the effector, and the parallel arms the hypotenuse.
