=Modularity=
 
*Different step motors and drive mechanisms can be mounted onto the axis support angles via mounting holes
 
*Different frames can be used, provided they have precise mounting holes for the axis support angles
 
*Different holding platforms can be used, provided they have mounting holes for the X axis moving angles
 
*Different spindle setups can be used, provided they have mounting holes for the Z axis moving angles
 
*Different stepper driver boards and power supplies can be used, provided they have compatible performance specifications within the electronics system
 
=Scaling=
 
*Scaling mainly consists of changing the size of the frame (to affect travel ranges) and the type of step motors (to affect travel rates)
 
*Other discrete components such as fasteners, leadscrews, and shafts need only be scaled if necessary for functionality or certain desired performance specifications
 
*The travel range calculation for the X axis:
 
(X Travel Range) = (Distance Between 2 Parallel Frame Angles Along Horizontal Plane) - (Length of Platform Along Axis)
 
*The travel range calculation for the Y axis:
 
(Y Travel Range) = (Distance Between 2 Parallel Frame Angles Along Vertical Plane) - (Length of Z Support Angles Along Axis)
