Ok, in order of posting:
Kramdra - Yes, a larger one probably could do fairings, although they'd be fairly heavy.
Blurredman - The plastic's fairly strong; I believe it's classed as an engineering plastic, and makes surprisingly durable rigid structures.
Marki - that's a fine offer; I may well give you a shout in the not-too-distant future. As to the 3D scanner, I keep thinking that I should design my own. The real problem that I'd have would be in designing the hardware to interpolate a stereoscopic video stream. I certainly don't have the money for an off-the-shelf unit, aside from the Kinect, maybe. ____________________ '10 SV650SF, '83 GS650GT (it lives!), Questionable DIY dash project, 3D Printer project, Lasercutter project |

if you scaled it up to 50 or 100% bigger would that dramatically effect the accuracy req to calibrate it
being the further it has to move the greater chance of error
or is there a fixed size that you have to stay within | Not really; the precision is determined by the motor's step size, as well as how well you assembled the printer initially. A larger print size only means more steps, not bigger steps, so you should still have similar precision.

I also used C and C+ back in pre historic days when I was program debugging | Yes, it's C++ - the only real guidelines are to try and keep it simple; minimise floating-point stuff, be pernickety about how much RAM you're using, that sort of thing.

For large machines I'd go for linear scale tape and encoders. Accuracy would be very good, 10 µm/m being a fairly low resolution. The largest measurement machine we have at the moment is around 17 meters and real world errors are around 0.2mm from one end to the other. ____________________ https://www.metacafe.com/watch/1972097/how_to_behave_on_a_forum/ |

Oh dear. I've just had to change over the hot end, because it burned out a couple of weeks ago, and decided to upgrade the firmware while I was at it.
Big mistake.
Looks like the firmware's been very actively developed in the intervening year since I last looked at the released versions. As such, I'm swearing at the (now significantly larger) firmware, trying to get it all to behave itself. So far, things I've had to complain at:
inverted motor directions,
inverted endstop responses,
incorrect stepping values,
totally insane heating speeds.
This list may grow. Either way, there's been one good spinoff from the insane heating speeds; the PID process in the new firmware has been massively improved, so after only two updates, I managed to get some good PID values in there, and it's now nice and stable when heated. ____________________ '10 SV650SF, '83 GS650GT (it lives!), Questionable DIY dash project, 3D Printer project, Lasercutter project |

So I'm very close to pushing the button on this -

and starting my own little journey into discovery of hair tearing innovation.
Any major hints and tips nowhere?

1) Do it, Faggot.
2) Be methodical, patient and precise. This is often best served by taking photos of what you're doing at every stage, for future reference.
3) Get friendly with the Arduino environment. You will find yourself re-uploading firmware multiple times, in the quest for perfect performance.
Give me a shout if you feel the need. ____________________ '10 SV650SF, '83 GS650GT (it lives!), Questionable DIY dash project, 3D Printer project, Lasercutter project |
