Our Huxley hot end kept popping out from the clamp, which was warping under the heat, and ramming into the print bed gouging out designs in the plywood.
Several iterations of clamp design later and we’ve settled on a beefed up version that seems to cope with the force of the extruder (even when I had set the Z STEPS_PER_MM to 20% of what it should have been). Continue reading Bowden Extruder Troubles→
The premise behind the Generation 7 RepRap electronics is replicability, so we decided to fabricate our own for our Huxley in progress. Originally we had hoped to set up our Mendel for milling with our Dremel, but with our sticky y axis problem being only improved but not completely solved by increasing the belt tension, we decided to play it safe and etch the PCB instead.

Having a working Mendel poses a difficult question – what to print next? After having successfully printed its first self-improvement, it is time for Mendel to become a parent! And what better solution to our portability problems when taking Mendel on the road than a “Mini Mendel”, aka Huxley.
When my father and I first embarked on our RepRap journey, there wasn’t a single one in the world that had actually printed anything. Forget cutting edge, this was bleeding edge technology.
Fast forward roughly 5 years: there are working RepRaps all over the world, and we are finally on the brink of joining this club. In the coming weeks I plan to record our experience of “the home-straight”, but first here is a quick summary of how we got here.
