MR AT-AT vs. ILM AT-AT...differences?

STEVE THE SWEDE · 11-13-2011, 04:03 PM

Json, thanks for posting that! I never seen that pic before! That's just amazing, not putting down anybody else's hard work but that's got to be best SS matching paint job I've ever seen on a walker.

Thanks again, cool of you to post it giving some well deserved credit to Jon.

Cheers,
Steve.

Ill see what i can do for you about the armature, no promess, i need to know first how long it takes to get all the parts CNC'ed. First I need to find someone to convert my plans into cnc readable files, I dont know how much it will cost me.

hi julien
"cnc readable files" does that mean you need cad or cnc toolpaths generated ? what software do you have to program your mill? 2d or 3d ? i dont know what program you draw with but if you want i may be able to help you out

Yeah, it was a case of "the normal fan isn't going to like an Imperial vehicle being so grimy and tan" I guess? Nutty.

Jon,
I guess yes that's what I mean, but TBH it's all new for me so I'm not sure lol

My drawings are .ai files, but the software used to program the mill is Mach3, do you know it ? I'm not sure if I can convert my .ai file directly into this software, I'm lost lol I'll probably have some questions... and one of them is in my head for months now... : how can I mill the side of a part then the backside without being misaligned ? (I need to mill both sides of the lower part of the legs and of some other parts...).

I bought the CNC, cant go backward now lol I hope the learning curve will be quite quick...

Hey there i hope u dont mind me trying to answere the question.

Is that the software u are useing? LINK
If so than it can import DXF files.
and the good news are illustrator can create DXF files.
That might be a solution.

one way of doing that is,to mill a holder for the part.

In theory u mill one side of the part.
then u mill the holder (or tool) to hold you part.
Then the other side.
But all that varies, depending on how the millinsystem looks and all that.

Hope that helped a bit.

be carefull converting .ai files to dxf as all lines and arcs have to line up exactly. ( lots of lines not touching means alot of wasted machine time and poor results ,that means alot more sanding which kind of defeats the point of maching it in the first place) Also curves and arcs that seem smooth as an .ai file can turn faceted (ie lots of straight lines , which again means alot more sanding) when converted..... I always end up redrawing everything because of these problems .

Machine flat things from 2 sides like Flixen said.....after youve machined the first side , machine the female shape in some material ( i use chemiwood) this will locate your part in exactly the right place.

hope this is helpful , feel free to get in touch if you need any more help...

Yes Felix that's the software I have, is it a good one ?

Thank you both Felix and Jon for the tip to mill the backside of a part, that's brilliant !

Thank you also for your help, I may need some for sure !

Felix, I can see you're also a R2 builder, I took the styrene way though (

), your aluminium astromech looks awesome ! Someday I could build an all aluminium one too !

I don´t know the software just looked it up to see what u are working with.
But as fare as i understand it, it´s a cnc controller software.
From witch company is you cnc machine?

Styrene is cool, aluminium is just to heavy, once u start with it.
If i would restart my build i think i would got with a hybrid alu wood plexyglas version.

But any way let me know when u need help.

Yeah weight is the bad point, but well... I still have in mind the pic of Lucas with the unpainted all alu R2 prototype... it's an awesome piece of work !

I dont like very much wooden droid, and plexi seems OK only for details not for structural purpose ?

I remember you sharing that information quite a few years back, since then I've been spreading the good word.

There was a thread that was identifying the kit parts on the AT-AT but I can't seem to find it (I'm looking for the guns mounted on the side of the head) - dos anyone have it bookmarked?
