Robotic 3D prototypers
At this moment, the assembly instructions are a bit sparse to say the least.
As usual, real world work has to take preference, and this weekend was no exception.
This week I plan to make a little time to take apart and put Morgan01 together again, taking photographs as I go along.
Awaiting wiring… This one is a thing of beauty!
Not a lot to be done, just need an hour or two. It should be running for the printing Demo at Unisa on Saturday. 
New motor mountings completed, RAMPS built and firmware uploaded. Just need a couple of small vitamins – both for my machine and for me…
My printer is about to become a mommy… They do grow up so fast!
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.
Next:
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!
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…
