Darwin Part Development
This interim page is designed to host the developments required to achieve Darwin's replication. It tracks only the cartesian robot, not the extruder which has already been replicated. Darwin was originally designed with a support material write head in mind. However, it is possible to achieve replication without a support head if some minor design changes are made.
