This weekend I made quite a bit of progress.


In these images you can see the updated motor holders, the new bed bracket with lead screw, and the power supply roughly in the right spot, ready for the electronics.

What you cannot see, is the new inner shaft of the SCARA drive, that now consists of the threaded rod and a 15mm copper pipe. It turns out that the elasticity of the rod itself is now the weak link in the design… The double shaft successfully dampens and oscillations that were apparent before.

Bed leveling, and hotbed. Building of RAMPS for morgan ( my current RAMPS is doing Ecksbot duty ), and the upgrade and mounting of the extruder.

Watch this space!

Frame update

Finally time for some work!

The frame, as it was up until now has some slight but problematic structural deficiencies, and it is time for a redesign.


The new frame still use PVC pipe, but used in a triangular configuration that should get rid of most of the unwanted movement.

In the photo below, you can see the pipe adapters during the print.  My first attempt last night was the victim of a filament spool tangle, and only printed half way…
