3D Printing for great justice. Now with a shoddy video!

[Ichy]

If you ever find 'something' that is worth printing in bulk then I would be more than happy to reverse engineer it.

Considering buying one of these next.

The accuracy is way off but they are cheap and loads of fun. It captures texture and colour as well as form.

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.

Can we see the headphone piece when it's fixed? Looks awesome dude.

bump

nowhere.elysium you are a cu*t
I've just read every post in this thread then been on you tube & google frantically researching this

can I ask a few quick questions
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

having seen a lot of the code you have posted regarding setting parameters, it seems very similar to PHP and other coding (hashing out irrelevant parts and manipulating variables)
I also used C and C+ back in pre historic days when I was program debugging
but been a while, and also used to set up Auto Cad etc on some well over spec'd PC's for some local engineering company's

is it hard to pick up the software and control systems with some basic background knowledge in electronics's and components
I did a degree in radio electronics's many moons ago and can use a soldering iron and know what a test meter is for and how to use it

so many more questions I'd love to ask but I've taken up enough bandwidth already

P.S. what happened to the secret project ??

have you started printing guns yet?

most printers done use stepper motors, they normally use a hefty motor on a pwm controller which is why they have the feed back strip (from what i under stand is magnetic but i could well be wrong).

as for larger print area, you could in theory increase the length of the screw, providing you are using something like a ball thread or acme thread accracy should not go down it would just take more steps to cover the legnth of the bed

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.

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.

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

https://reprappro.com/shop/machine-kits/mendel-full-kit/

and starting my own little journey into discovery of hair tearing innovation.

Any major hints and tips nowhere?

thinking I should just dive in to be honest!

Man, completely forgot about this. Mine has been untouched in a cage at work for a few years.

Also NE, whats the largest your laser cutter can do? May be PMing you soon for a quote.

the current ones can do 1200*900mm, but the big one that I'm aiming to get will do 2400*1200.

How's the printer going N.E?

My interest has just been rekindled after we bought one of these:

14 micron layers and support material.
