Optional Configurations
If you wish to change the designs built into this system, options are outlined below.
We do not support systems with such
changes, so the user must be aware that they will be responsible for their own technical support.
These options are only
provided for the sake of completeness and transparency.
Option 1: Less Functional Model
Some have expressed the desire to build a system which is not as fully functional as outlined in this document. For example, they
only want to drive the spindle.
That is very doable but is not an option we will be providing. The components which can be left out when building the system
are outlined in the table below.

Regarding limit switches, none are truly required. These can be added later as desired. If not used, the 3.5mm audio jacks are
not needed.
Recommendation
Except for the DM542T Stepper Motor Drivers, there really is not any significant cost advantage to taking this approach. So, if you
do desire to make such a change, consider populating the Printed Circuit Board fully (8 resistors and two 74HCT245s). The
DM542Ts can be added when you later want to expand to use them.
