Engineering and other random stuff
One of the more interesting components in the Mark2 3D Printer is the Z probe, an IR probe that precisely measures the height of the bed for automatic bed-levelling.
This is the first product that I’ve needed to program and test, and I’ve had some fun along the way trying to make the process faster.

The mains input sockets for the Mark2 printers arrived today – I had some fun wiring them up, and I think they’re going to be included in the printers going forwards.

I’m almost at the point where I need to lock the design down and start kitting things for the December launch – a pretty daunting prospect, I must say. Before I finalise things, there’s one last idea for an improvement that I’ve been thinking about for a while – and

I previously discussed my intention to develop an expansion board to add a few extra controllable fans to RAMPS. I finally arrived at a solution I’m happy with – TinyFan.

One of the problems I’ve encountered in the past when using RAMPS electronics to control a dual-extruder printer is the lack of sufficient fan support. Dual extruder setups can require a few fans, usually one controlled fan (for cooling the print) and one or two always-on fans for cooling the

Testing out the integrated spool holder today – let’s see how well this thing works!

Prototype frame is in from the laser cutters! Time to start testing stuff!

After a few months of working on the design in the background, I’m ready to get the first prototype frame cut. Check below the break for images of the current design!

I thought I’d take the time today to talk about a few of the things I’m doing during development of the MK2 printer to address a few problems in the MK1, and how I’m trying to keep the design as flexible as possible.

Last year I purchased an Oculus Rift DK2 – I’d like to say I bought it as a developer, but really I just wanted to play around with virtual reality stuff. I mean, who doesn’t? This year my final year project is centred around a “3D Viewing Platform”, or “tele-presence”
