Another 3D Printer
Joules:
Bill, the Kossel is open source, what you see and what you get off ebay in my case have never been one and the same. I like to support UK business, as any problems I like them to support me. The money spent on the Kossel I posted also helps fund its development. Buying from overseas tend to be into one persons pocket as they rarely contribute back to the community that developed the idea.
The Duet is not standard to the Kossel range yet, and prior to it I wouldn't have bought the Kossel as a serious machine. Things like linear bearings and metal parts can be added later if required, and can be manufacture/fabricated in house if you have the facilities.
Oh, the other important point for me, this version uses an E3D V6 printhead, and that's not to be sniffed at if you want decent quality work.

:thumbup: Fair enough :)
I'm giving this serious thought , it only costs about the same as one refill for the works Objet30 (which is great but ,so slow and stupidly expensive to run)
BTW have you tried vapour or plasma smoothing ? (I came across it while youtubing)
Joules:
Nah, I use H2O MOX abrading.... :med:
Rub it with damp wet and dry paper.
Joules:
A medium sized heavy package turned up this morning. So once another :coffee: open it up.
:bugeye: STREWTH, I've been had it's really dense newspaper !!!
Pulling away tear soaked paper revealed the goodies, and so to unpacking.
First out the electronics, very nice well packed and the wiring loom complete with labelled plugs etc. The hot end is assembled and wired with localised connections. I will be able to swap the entire head to try different materials without fear of cross contamination. The re-purposed Dell PSU is a beast, 12vdc @18amp.
The heated bed, glass and bag of test PLA, spiral wrap for wiring and ptfe tube for bowden feed of filament. The heater is assembled and of good finish, they have removed the burrs off the top where the countersink screws are fitted. Good attention to detail and ready to be used.
ABS printed parts, I still have no regret using PLA for my prototypes. The parts seem good, not warped a little clean up in places wouldn't go a miss, but not a requirement to use them as is. The extruder is assembled and the one component I would exchange for an all metal extruder. I doubt anything will be wrong with this extruder and have confidence it will perform, but I just like the control an adjustable all metal extruder offers. NO, not a cheap China extruder they have some nasty design flaws, such as lack of support for the filament coming too, and exiting the pinch roller, allowing the filament to buckle then suffer feed failure.
And here's why I am happy to pay that little extra, genuine Misumi 2020 rails, they should be dimensionally accurate, STRAIGHT and hard anodised. I have seen some awful rails and it's attention to detail and quality thats going to give you the fighting chance of decent prints.
Now going over this machine it looks a good deal for the money, big support community online and it's in constant development. Downside for some, its going to be for smaller prints (though big enough to do the Quorn components). The working bed is 170mm diameter, giving you a block of 120mmx120mmx245mm and you have to build it yourself. I would really suggest looking at the Rostock Max V2 if your requirements are for a larger machine of this style. Box now sat in office awaiting time to start construction. I am happy with what I got as a kit, only time will tell if the print quality will be enough for my demands, but once built I doubt I would loose money selling it if I can't get the print quality I am after.
Missed the picture of fasteners, steppers, GT2 timing belt and they even include the tools required to build the machine.
Will_D:
That looks dangerously desirable.
I see why they named it after a genetiscist! Can just see the DNA spiral being printed!
I note on the page that there is an optional touch screen is that needed?
Also what resolution do you expect, they state 100 steps per mm in all 3 axes(10 micron) and repeatability of 30 microns.
What is the minimum layer thickness it can lay down?
