Tuunyyte at h4hjozi

It was quite a successful (but sadly intimate) evening at h4hjozi. I managed to hack the printrbot together again after the unfortunate meltdown we had 2 weeks ago (note to self: don't leave PLA parts in direct sunlight during a heatwave again).

After checking all the axis and endstops and re-leveling I printed my trusted quicky print: a butterfly fridge magnet. I printed one for our fridge but kept on giving it away so now, I make sure that I always keep a spare one around in my print demo box.

Devin also finally managed a good gnu print at h4hjozi which is a great relief. I think I would have given up long ago if I had to suffer all the inexplicable problems he had. Just overjoyed that it is finally working \o/

I think this is a new h4h jozi meetup record: 2 working printers, each creating something successfully.

First proper prints on the h4hjozi printrbot \o/

Yesterday I finally managed to finish calibrating the 3d printer that I've been building for about a year now. I didn't spend enough time on it before, but since I've joined the 3D Printing community on Google+ I got more focused on actually finishing the thing.

This is the first non-calibration object I printed.

(I forgot to turn of the anti-gravity engines for this video, sorry).

With the addition of the fan and properly levelling the bed things started to look much better. However when printing thin walls I kept on seeing "row of dots instead of a line" and it was not laminating properly. The parameter in slic3r I found that helped was "Extrusion multiplier" and I ended up on 1.75! I just realised though that I should have rather increased then hotend temperature above the 185°C I was using... will do that next time :)

As you can see I printed some stubbys (one with a screw on bottom and its main body printed with support) and a couple of rings.

The thread actually works!

Thanks to openhardware from where the printrbot was sourced. A lot of additional community support came from Org and Gert from house4hack, thanks a lot guys!

Update: printer layout for KobusJ:

h4hjozi first fully wifi-internetted meetup in the cave

I arrived early and managed to get the wireless internet working! Dhcp forwarding made it very easy, except I don't know what the router's IP is anymore :(

Marcel and I were still standing around when Schalk and Guy flew in and had the place re-arranged to our customary layout in no time.
