Thanks for the tip At the moment, it's a coin-flip between a J Head and the Arcol one, although I've been told that I would need to print a different x-axis carriage for that. A bit of a chicken and egg situation! It may be the same problem with the J Head though.

So, last night, a tragedy happened. I was trying to print something in nice colours for my girlfriend, but it seems my nozzle didn't like this new plastic and jammed. The pressure built up while I wasn't watching and warped the plastic barrel (PTFE) and its join to the brass nozzle. The nozzle may be unblocked but this insulator is fubar. The hot-end design was a old one that put too much stress

I have to say Greg, that is a lovely smooth print! The infill every n trick is particularly useful too, thanks
These competitions started at a perfect time for me, as i had just finished my printer and done some calibration and wanted to see what it could do. It might be worth building up an assault course of objects (preferably aesthetically pleasing or useful) and detailing issues highlighted

Congratulations I've only just thought to come back and check this thread (lost notifications for some reason!)
And finger's crossed for the Makerfaire application - I hope you get it, Richgain! I'm unable to go this year, but it's normally a great event

I had one last go (and made a timelapse of it!)
Printed in 36 minutes and wasn't too bad! Some of the ambitious overhangs
curled a bit and the head caught some of them causing a good proportion
of the stringing.
Any tips or hints to help reduce the bobbling on the overhang sections would be appreciated!
The bridging at the top was a bit ropey too but managed to complete. It
struggled po

Stringing seems to occur when the move from the end of a perimeter to the next one trails over a part of the hot, recently laid perimeter, especially an overhanging one. Subjectively, it looks like they are the most prone to swelling or curling up after being laid down.
I need to pick up some calipers to check the filament width too, in case it's wider than I think leading to the gcode extruding

A tricky print to get right, this one. I've tried a few times now, going for as much speed as I can without sacrificing too much quality, but the strands are a little too thin for my setup to do cleanly I think.
My second attempt was a decent balance, but with quite a bit of stringing (I'm having a few issues with that at the moment ) Stringing seems to be from deposited plastic and not from the

Just to add that the biggest hurdle to overcome with using the RPi as a host for pronterface/slic3r/sf/etc is that its video core supports OpenGL ES 2.0 and not fixed-pipeline OpenGL. Not only that, but currently, there is no way to get an OpenGL context through X11 to render with but that will change in time I hope.
IMO Anything that requires Sun Java + Java3D looks like it will have the most i

Congratulations Billy! And thank you RichRap too!
It was only because the footprint of the object was so small that I was able to get away with not using a hotbed!

First of all, thank you @richrap - without you preparing @dizingof's awesome model for smaller printers and suggesting it as a test, I would never have even attempted something as complex as this.
It's not a great print, but I am chuffed that it completed it successfully! Printed on a young Mendel (just got round to finishing it off a few weeks ago) and I am still tweaking the settings.
