First TVPrusa printers are printing!

Michel Pollet’s amazing Sappho’s Head print

At least three of our 20 first round TVRRUG printers are producing prints!

First past the post was Michel Pollet, and the quality he has achieved in just a few short weeks is absolutely incredible. As a reward, Michel has been helping us test and fix the electronics and give the rest of the group a helping hand. Continue reading First TVPrusa printers are printing!

GRRF RAMPS 1.2 Electronics Build

Our RAMPS 1.2 Electronics kit arrived from German RepRap Foundation the other day so I got cracking! Unfortunately I has having one of those days and my German and Google Translate weren’t too great, resulting in several LEDs with the wrong orientation and one in completely the wrong place! Thankfully everything still works (except the LEDs). Continue reading GRRF RAMPS 1.2 Electronics Build

Bowden Extruder Troubles

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

Gen 7 Up and Running

The trial run at making our own Gen 7 PCB was a success, so we ordered the components and went for the real thing. A few tricky obstacles required surmounting including out-of-date config files, a blown Pololu and invisible shorts, but finally we have life! Continue reading Gen 7 Up and Running

Etching Generation 7 PCBs

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.

RepRap: The Story So Far

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.
