Overview
This is a delta RepRap design named after Konrad Lorenz.
There is nothing majorly innovative about it, but it was designed with the following in mind:
Few trailing wires - they are buried in the prints wherever possible
Generic axis that can work for a delta or Cartesian design
No timing belts - the drives are fine wires coiled on smooth pulleys
No bearings - or rather printed bearings running on PTFE sliders made from Bowden tube
Hollow axis rods to allow services to run up the middle of them (including the Bowden tube)
Axis rods used also as electrical connections
Adjust, clamp, then glue to get accuracy in the dimensions of the machine
and
Almost all fixing screws are self-tapping, so few nuts
It’s not yet complete, but if you want to get the CAD files it’s on Github here. This page will be updated with further details soon.
