Triton v.0.1 delta printer


Hi,

@All: Meet Triton 0.1 ... Triton meet @All 

Image above is what it looks like currently, and a view of my messy desk. 

BIG FAT NOTE: Design might completely change at will or necessity. I can provide the STL's for current stuff but will not post them until I get to a stable form. 

Software: 

- 3d design - good olde Blender

- firmware - Repetier Firmare latest git development branch

- host - Repetier Host 

Electronics:

- Arduino Mega 1280 

- RAMPS 1.4 shield

- 3 x  Pololu drivers. (will need to add another for extruder) 

- hotend - probably J-Head 0.5 nozzle - TBD

- thermistor - EPCOS 100K 

- limit switches - normal switches

Mechanics: 

- no belts, cable or threaded rods - it uses threadless ballscrews - http://www.thingiverse.com/thing:139425

- 3 x second hand nema 17 stepper motors - 200 steps/mm 

- 3 x lm8uu bearings 

- 18 x 623zz bearings for the screwless ballscrews

- 3 x 608zz bearings for the tops of the rotating rods

- 3 x 30 cm high quality steel rod

- 3 x 25 cm h9 stainless steel rod - that would be the cheaper rods you can find here and there with a rougher finish (high quality rods should work too but slipping is more probable)

- 3 x 30 cm makerbeam

- 6 x 20 cm makerbeam

- makerbeam angle brackets + bolts + nuts - complete list TBD

- printed parts - list TBD still a WIP

Next ... well some parts might have to be redesigned, some still need to be designed, now waiting for the bowden parts from Jinx. 

Thanks Jinx!

Update - 2013-12-14 - Bummer!

Good news:

- my PFTE tube and fittings made it safely.

- the Jhead mount is nicely fitting 

Bad news: 

- the tube fittings are on way ony - put them on and you can't get them off again - of course I was eager to see how they fit now I'm stuck with them on the tube

- the whole arm+efector+mount assembly is way too weak to handle the forces applyed to it by the 3 mm filament + pfte tube - so with the tube attached it won't be able ro keep the print head in one position :( .... really strong redesign is needed

- my BB (current printer) is getting old it may fail real soon if I don't do something about it

So all the above given and the lack of cash leaves me with no option than to shelve it for a while, cool down and rethink stuff.

Cheers!

We do have delta printer in the office. It's insane fast printing...much faster than to common 3D printers like Makerbot...

Nice work TinHead, will watch the updates/upgrades.
