Key specifications as described by the developer:
- It is highly printable.
- 153mm arms similar to RepRap Morgan
- Gear reduction similar to RepRap Morgan
- Same kinematics as RepRap Morgan (Well...this can change arm modes but we won't start doing that until after we get some prints.)
- Fits in a 200x225x250 box
- Can print objects that are up to 600mm long
- All four motors (400 steps/rotation) are static while providing a structural support and their own wire-management.
- Prints directly on a tape covered table
- Planning on using an IR depth probe
- Could probably print all the parts for a self-replication run in one go.
Here is the sequential printing on a flat table surface with some blue tape demonstrating the advantage of this machine:
Great work by Nicholas Seward! Since this is a project in development we can expect much more improvements.
