Mendel vs. Darwin
Mendel is the latest generation RepRap machine. Mendel supercedes the first version, which we call Darwin. For RepRap Version I "Darwin" instructions follow this link.
Mendel has the following key improvements over Darwin:
- Bigger print area, smaller machine footprint
- Improved constraint on the z-axis to eliminate jamming
- Better axis efficiency
- Simpler assembly
- Capacity of tool changing
This video illustrates these improvements:
