I think that's my problem. Not that i'd be in a hurry to spend £5000 or whatever it is for a big ultimaker or a replicator or a duplicator or a binglebot, where all their budget seemed to go into getting some 'baby's first industrial design' shell made for it. But that I kinda wanted to prove a point in building my own machine but i'm still not entirely sure what that point was supposed to be. I guess just that I hate most of the designs out there for one reason or another and thought I could do better. But now i'm not so sure.
Actually i'm sure if I actually comitted to any of my shoddy designs they'd be better than a good chunk of the stuff out there, even commercially produced stuff with multiple thousand price tags.

They really went to town getting the cost/quality down 8-( Maybe they raised their game again, but looking at the review ratings I think not. A couple of Mini Kossel printers, but they still out fox me with the complex setup every time you change the firmware, I will get the better of them. A now defunct Printrbot Metal Plus is the last on the list and being rebuilt with a newer 32bit Duet board and E3D hot end. Some of the old printing posts mention the Mini printer. Prior to all that I started out with a loaned Rostock Max 8bit delta. If you wanted an excersie in frustration that was the printer to have, but I learnt a lot from that machine.
PK, I have just been lucky, right place, right time. The people who have prints off me use them for presentation, brain storming or just to get an idea of what an injection moulded part will look and feel like in its application. Only one client uses direct printed parts from me as end user parts, the setup cost for the intended mould was £10k plus and he can just call a print off as and when with modifications only needing CAD tweaks before the print. We did test the end user acceptance to printed parts first and they had no problem, but it’s a very bespoke product.

Looking at the rise and fall of several companies it seems to be that they all die when they decide to exchange a decent design for a scaled back design in some sort of Star Trek minifridge designed by people who only know bad videogames.
I had a good laugh at Solidoodle's goodbye message.
A few years ago Solidoodle was one of the leading manufacturers of consumer 3D printers, with 70 employees and over ten thousand units shipped. Regrettably, we stumbled on the launch of our 5th generation product, the Solidoodle Press, which fell short of our high standards for providing an outstanding consumer experience. This led to a downward spiral of declining sales and layoffs that further hindered our ability to deliver a great consumer experience.
Phrases like Consumer Experience are so insane to me, especially in this context.
I guess it's a tricky market as the fad died out and the Chinese undercut everyone, but trying to trick people with a fancy exterior is just plain dishonest.
Also seems Windows installed but its refusing to activate for 'security reasons' and refusing to download updates. A restart might fix it but i'm done for today.

Had they arrived on schedule, we would have had much more time for testing and inspection, and would have realized crucial cash flow much sooner.
Seriously this corporate talk cracks me up. It's the way they can't shut it off when addressing the public, like they fully believe in this language and it's message. I wonder if there are any lawyers out there that talk legaleze in casual conversations.

I've gotta chime in...
My exactly constrained design is a 15" class machine. The Y axis is overhung from the main Z rails. A key technique I used is having one thing controlling each degree of freedom. As an example, the Y axis has wheels running in grooves on the left and wheels running on FLATS on the right. That way, the alignment of the Y rails isnt important.
That said, I found that my Y 20mm square rails sagged more than a layer under load, but repeatably. I used mesh leveling and totally solved it.
If you have a CNN and/or a plasma cutter, my design is easy to make.

Finally got windows update to work. On the 32 bit version it just... worked. And installed everyting, graphics and audio drivers and all. But for some reason on the 64 bit version it took alot of searching and various tedious workarounds to get it to work, including reinstalling the operating system yet again.
I also had to reinstall it again after I somehow managed to set a password I couldn't re-enter. Guess my fingers were misaligned on the keyboard in some manner while I was half asleep.
I know all this has nothing to do with 3d printers, but I haven't had a chance today to even think about them. Reinstalling an operating system once is a bit of an adventure, but after 4 times it just becomes a little more hopeless feeling. I think when I get my PC back i'll start looking harder at whats actually on the market. There's stuff like the CR-10 I believe that retails for quite alot for a machine assembled from extruded profiles, but maybe it'll look more appealing if I actually price up assembling something similar. That said I don't care much for the whole Y axis on the table design that's quite popular. Having to move a changing mass and also taking up alot more desk space than neccecary for the movement.

Another look at gumtree and this has come up. And only this.

Not about to rush out to buy the first thing that appears, and i'm not super psyched about delta machines, but doing a quick read suggests its a RAMPS1.4 based thing. Which along with an arduino, 4 stepper controllers, and 4 of the cheapest motors on the one website I was looking at comes to just about £100. That'd also not be including a power supply or the whole extruder deal. Hot ends look easy enough to make with a lathe. So I guess that asking price isn't too riddiculous, but I still don't think it'd be Massive Savings over buying the parts. Especially since I don't think that machine itself looks very good.
