I realise that your post was nine years ago, and that you therefore made this 34 years ago, but do you have any published documentation for it?

Just a quick post to say that today is RepRap's 10th Birthday.
At 14:00 hours UTC on 29 May 2008 at Bath University in the UK the first child RepRap Darwin printed on the original parent RepRap Darwin and assembled by Ed Sells, Vik Olliver and me printed the first grandchild RepRap part.
Without the thousands of RepRap volunteers, tinkerers, writers, makers, doers of RepRappy things (and critic

Hi All. I don't administer the reprap.org server; other kind volunteers do that now that I am retired. I have just e-mailed them and we'll do our best to fix it speedily.

Also the Christan's fork of RepRap Firmware (https://github.com/chrishamm/RepRapFirmware/) has a section instigated by me to control a Roland Modela CNC mill.
The Roland talks its own language as opposed to G Codes, so this takes G Codes and translates them into that language for transmission on a serial port from the Duet to the Roland at 9600 Baud (which is what it likes) using a piece of el

Hi Everyone,
I have received another invitation to speak that I cannot go to. If anyone else can go, please respond. Here it is:

I hope, in this post, to inform you about a number of things to do with RepRapPro Ltd:
1. What happened to RepRapPro Ltd?
We were making a profit, but that had been falling. We decided to close while we still had some funds and no liabilities.
The closure may be permanent, or it may not. There are other people interested in buying the company, and one of those deals may go ahead. If no suc

As you might imagine, we have all been rushed off our feet in the last couple of weeks and will be into the near future. When you close a company, the amount of work multiplies extraordinarily.
However I have been writing a long post for here on what happened, is happening and will happen. As soon as the second two stop changing faster than I can write them down, I will post it. My best gues

Great! And I guess a fourth function of this topic could be for people to post trailers for RepRap talks they are giving. We could start a mailing list, but would that achieve anything that we can't do on this forum?

Here is a list of the characteristics that I think a solution should have:
1. Continuity - the existing content should be preserved and then new content will be added to it.
2. Continuity - the existing users should automatically have accounts on the new system (maybe with a password reset...).
3. The new system should first appear (as reprap-new.org) with ephemeral content as a sandbox for user

Matt is not quite right when he says that I, "steadfastly refuse to make any decisions regarding this matter". I have repeatedly said that RepRap has some money that could be used to solve the problem, and that - if the community and admins put up a single, coherent, agreed, budgeted proposal - then I will pay out funds to make it happen. If needs be that could be a combination of a one-off sum p

Here is the invitation that prompted me to start this topic; I have been talking to Ms Wang since she sent this. I can't go, and she asked if I could find someone else. If you can, please contact Ms Wang and post here so that people can know that the event has been taken care of.

I get a lot of requests to fly all over the planet to talk about RepRap, which is very kind of people. But I have a policy of accepting no more than one per month of these (otherwise I'd spend my life in airports...).
So the purposes of this topic are threefold:
1. People who know RepRap can post here to volunteer to give talks,
2. People who have received invitations to speak on RepRap an

Can you send a quick e-mail to support@reprappro.com describing the above, and we will sort things out under your warranty?

First a big thank you to all who volunteered, and - of course - to Traumflug for organizing this.
I shall give him root access to the server, and then we can take it from there.
My thanks again. I really do appreciate it.

I agree that things need to be fixed.
I don't have the time to do it myself. But if people would like to organize themselves to do it, I will facilitate that in any and every way that I can.
When I say organize, I need a list of names (and e-mail addresses, but I can get them from people's names on this forum, so I just need the names).
I would like one name at the head of the list (agreed

The PTFE heatshrink definitely needs to cover the entire thermistor in a continuous tube, leaving about 8mm bare at the ends for the connections. Otherwise it won't fit properly.
The thermal effects of the PTFE are negligible - the entire thermistor + PTFE is enclosed in aluminium at the temperature to be measured, so in the steady state the thermistor will be at the same temperature as the alu

Hi all
The MOSFET (IRLR3636) datasheet specifies an operating temperature range of -55°C to +175°C, so it stays cool (by its standards...). Its on resistance is a mere 7 mohm, so it dissipates no appreciable heat itself.
And the arrangement of having the MOSFET on the bed is neater for several reasons. It means that all the bed current (which is the highest in the machine) doesn't have to be

Dark Alchemist - if you want more than a carefully researched, thought-out and reasoned 850-word essay (and it's certainly not obvious to me what more anyone could want - perhaps you might give specific examples?) then I am not the person to provide it. Nor have I ever been, nor would I wish to be.

Thank you, Idolcrasher. And of course your love is reciprocated.
I try to refrain from commenting on many many things here and similar elsewheres - I think that people attach far too much weight to all I say. Most people (certainly including me) have strong opinions about what should, or should not, be done in the world. But I like to remind myself that (again like most people's) my opinions

I make money out of Makerbot (a small amount) and I make money out of RepRap (a rather larger amount, via RepRapPro Ltd). The tiny percentage of Makerbot that I own means that I have no control over what they do. RepRapPro Ltd (which is run by me, my family, and friends) is completely open-source - that I do have significant control over.

Congrats on the win, Rich.
Nice to see a challenge based on 3D Voronoi structures. There's a bloke called Adrian Bowyer who is famous principally for a thing called the Bowyer-Watson Algorithm, which is one of the standard ways of computing multidimensional Voronoi diagrams. I wonder what happened to him?

Of course, it may also be possible to reverse the current and cool the bed when a print has finished to detach the printed parts by differential contraction. They could then simply be swept off the bed by lowering the X axis and then moving Y.

There used (long before most of you lot were born) to be an actor famous for - as far as I can remember - his ability to raise one eyebrow a prodigious amount. He was called Leonard Nimoy. I did that eyebrow when I read that I was being called selfish for _not_ realizing an asset :-)

I personally own reprap.org.
I have no intention of selling it. It could rise to $1Billion, and I would remain unmoved. That's not what interests me, because I am very stupid.
The £3M figure is extraordinary, but - as has been pointed out - the value resides in its remaining as it is.
