Lorenz

As followers of this blog will know I have been working on a new RepRap delta design – Lorenz.  It has a number of novel features and it also contains a very high proportion of self-printed parts.  I haven’t finished it yet,

A characteristic that a lot of 3D printers share is having wires running all over them.  These are often neatened in places with cable ties, but they still look scruffy and often get in the way of the machine moving,

Bye Bye Belts! RepRap Lorenz does not use timing belts.  Instead it is driven by wire wound helically on a pulley on each stepper motor. The error caused by the change in wire angle as the helix winds 300mm of wire is about

  I am creating a new delta RepRap called Lorenz (after the noted biologist Konrad Lorenz).  It’s not yet complete, but if you want to get the CAD files it’s on Github here. This is the first of a series of posts about aspects
