Upgrading to a E3D Titan Extruder

Last week, E3D launched their Titan extruder – As I’m a fan of their existing V6 hotend (and am considering a  Chimera dual nozzle setup for a future upgrade) – I got straight down to ordering one.

My Think3DPrint3D (T3P3) Kossel Mini is currently using the geared extruder in a bowden configuration that T3P3 supplied as part of the kit – an extruder that has served me well so far (and one that I’ll be keeping intact as a backup for future use should I decide to go for the dual-nozzle setup in the future)

If you’re not familiar with Titan, it’s a conventionally manufactured extruder drive using a NEMA 17 motor. As uses specific precision engineered drives instead of the usual “hobbed bolt” common on RepRap designs.

Using a manufactured extruder drive might not be true to the ethos of the reprap philosophy – open source, and 3D printable wherever possible – and there are already great printed extruder designs out there – but I want a printer that is low maintenance, and when maintenance is needed, is easy to maintain – the T3P3 extruder, whilst compact and powerful, has some disadvantages – there’s no easy access to the hobbed bolt that drives the filament for cleaning, and doesn’t have any kind of spring tension adjuster – all things that the Titan has.

Although the image above from E3D shows the Titan in it’s direct drive configuration – I’ll be using it in a bowden setup (as is common for Delta designs) to reduce the moving weight of the effector of my printer.

I plan a series of posts to cover the installation and calibration of this new extruder, along with any problems I encounter along the way.

Pumping Iron

As a new push towards weight loss (and I know we’ve heard this all before…  several times…) I’ve hired a personal trainer to help me out both in the gym, and with diet and menu tips.

First impressions are good – he’s pushing me hard in my first couple of workouts, but not too hard that I don’t want to carry on…

There will be a few blog posts and twitter updates on the subject, some may include progress photos – but as I’m gathering a lot of data on the workouts, I should be able to record and show some progress!

Anyway, here’s the generated weight graph – and “how much I’ve lost” ticker from My Fitness Pal – I won’t comment on it as it should stay up to date, and so anything I write will not stay applicable!

Are you shaving your yak?

As an IT professional, I often find myself yak-shaving – if you don’t know the term, it’s basically the end result of a series of possibly unrelated and (more than likely) unexpected hoops you need to jump through to do something – it’s a term I’ve only recently discovered but am now using more and more often to describe aspects of my job that aren’t actually “doing the thing I’m trying to do”

Seth Godin has a great example on his blog which does a nice job of explaining the term – Don’t shave that yak and there are many other examples out there… (e.g. this one)

Escaping

At the weekend just gone, a few of us went to try out the new Escape Room in Cardiff

Obviously, this review won’t include any spoilers for the specific puzzles we encountered on our quest to Find Sherlock

On arrival we were met by the staff, given a health and safety briefing, asked not to take cameras or phones in with us (there are lockers for safe storage of things you don’t want to take in).

We were taken to the room, and locked in – don’t worry if you are claustrophobic, there is an “emergency exit” button in the room, and the staff are monitoring progress through the cctv cameras.

The puzzles themselves were a mix of those we’ve seen before – find clues which lead to combinations for locks – mixed in with some cleverer puzzles I’d not seen before – but that gave us a few “ah-ha” moments during the game – which is always very rewarding.

Suffice to say, we enjoyed the experience and will definitely be going back to try the other rooms on offer 🙂
