Posted by: Buster44 - 1 hour ago - Forum: Buster44 - No Replies

Hi,
Just thought I would share my progress with my R2 build. I have opted to build the little chap at 75% of its actual size. He will be a static build with the intention to use him as a small computer/server case.

I am using white and silver ABS in a hope to simplify painting afterwards. 

Printer Flashforge Creator pro

Cheers
Buster

  Hello from Northern Ireland!!
Posted by: Irishdroids - Yesterday, 01:22 PM - Forum: New Members - Replies (3)

Hello Fellow Droid Enthusiasts! 

I currently Live in Belfast, Northern Ireland and I had previously been lurking on the Astromech.net site for a few years, dreaming of one day starting to build my own R2 Droid.. I had previously been looking for other droid builders within Ireland but have yet to come across another like minded Irish soul, but I am still hoping there are others out there.

I had been wanting to build an Artoo for the last 20 years, but it honestly seemed that I wouldn't have had the time or the resources available to create my own, until the advancement and adoption of 3D printers.  I had been looking around the web for looking at various build projects and stumbled across MightyJabba's youtube videos, they honestly were a huge inspiration, and led me to buy my first 3d printer [CR10s]... a droid of my own didnt seem so far out of reach anymore. 

I have since started building from Michael Baddeley's files, I honestly cannot thank him enough for sharing them with the community! 

I am now at the stage where I almost have my dome done.  I printed it in PLA, but I am not happy with how some of the parts have turned out, and I definitely need to refine my cura settings for an improved finish.  But I will say that the last 7 days has been the most fun in my workshop that I have had in quite a while.. 

I also need to start a build log somewhere, just to track my own progress and to share thoughts and ask for information within the community.

Thanks so much for accepting me on the forum and looking forward to collaborating with some of you soon.

Martin

  Hello from London
Posted by: Buster44 - 08-19-2018, 01:46 PM - Forum: New Members - Replies (1)

Hi,

Thanks for the add and special thanks to Mr Baddeley for sharing his files.

I live in West London and old enough to know better and should be spending more quality time with my wife, apparently.

I have been printing parts for the last month and eventually started to solvent weld them together last night. Started with the skirt and I am very impressed hows its coming together.

My R2 is going to be at 75% size, printed on a FlashForge creator pro in ABS. The printer has been upgraded with TMC2208 drivers(I had to make a custom PCB to fit these) and new larger aluminum build plate. I am considering purchasing a 500 sized printer.



Cheers
Buster

  R2-D2 Goes To Dover Comicon
Posted by: Eebel - 08-19-2018, 04:53 AM - Forum: Eebel - Replies (9)

So, 

My first foray into the public was at Dover Comicon.  Her are some pics and lessons learned.

After 20 minutes of "dancing" around R2 stopped moving properly.  When I got him home I found this damage.

[Image: attachment.php?aid=1011]

The temps on the motor melted the drive wheel.  Booo.  I am going to reprint in Nylon, Hopefully, this will solve the melting problem.  I'll keep ya'll updated.

I'm taking my R2 to Dover Comicon on Saturday.  Anyone have any tips or recommendations for getting him from my vehicle to indoors?  I was thinking a cart, but most of them are too narrow.  Has anyone built a custom droid dolly?

  R2-D2 Sonotube subwoofer.
Posted by: Laserman - 08-17-2018, 02:16 AM - Forum: Off Topic - Replies (1)

I just finished building a sonotube subwoofer, and realised the sonotube is roughly the same diameter as R2.

Now thinking about building an R2 Sub!

  Dome electronics
Posted by: Martyman - 08-14-2018, 10:48 PM - Forum: Martyman - Replies (4)

I got my R-Series logics yesterday. I have assembled the rear and one of the front logics together.

For anyone who doesn't know the r-series logics, they are an attempt to get more screen accurate logics. The originals were created using fiber-optics running from a colour wheel. The r-series use (hand cut) fiber-optics from full colour LED arrays, and can be programmed for many different colours and sequences.

One tip I would share is to fully assemble the plastics AND LED boards before taking the electronic boards back off and stuffing with the fiber-optics. I did all of the large logic and then realised that I had the plastic frames in backwards and they would not line up with the LEDs no matter which way I flipped them. So rather than having each fiber-optic carefully trimmed to suit each location, mine are now a bit random, and it is not as neat as it should be.

Unfortunately, the Baddeley logic surrounds do not fit the R-Series logics which seem to have the same mounting holes but are larger in every other way to the standard tecees. I will whip up a quick remix and post to the parts section.

  Battery Box Hoses
Posted by: Eebel - 08-13-2018, 02:16 AM - Forum: Eebel - Replies (4)

So, I am to the point where I needed to finish up the details on R2 and I have been looking at different options for the battery box hoses.  I looked at real braided hoses and found that they were a lot of trouble to work with and I could not find suitable hardware to mount them.  So, I decided to give the printed hoses a try.  Honestly, I thought they would be impossible to print and the design seemed optimistic.  However, after much trial and error on the flexible hose print settings, I got some decent hoses.

So the next challenge was to bend them into shape.  At first I tried filling the tubes with sand and using a heat gun.  The sand prevents kinks.  However, this was taking forever and was very messy (sand gets everywhere.  hehe). So then I tried printing the interior tube guides.  I used PETG, since it is strong and a little springy.  I was able to use rubbing alcohol as a lubricant to insert the guides.  For the first part of the guide, I just pushed it into the tube.

[Image: attachment.php?aid=956]

Then, I used pliers and a twisting motion on the tube and was able to push in about a quarter inch at a time until they were entirely in the tube.  The design has the knurled knob fitting onto the end of the guide.  However, I had distortions in my print and ended up cutting about half an inch off of each end for the knob to fit inside the tube.

[Image: attachment.php?aid=957]

[Image: attachment.php?aid=958]
Then, I got a pot of boiling water and ice water.  About 15-20 seconds in each one.  Then test to see if they fit the proper path.  Each curve is unique although they are mirror images.  You should have your battery boxes nearby to test after each bend.

[Image: attachment.php?aid=959]
[Image: attachment.php?aid=960]
For the ends, I heated it and held it in place to cool bit before hitting the ice water.  Remember, be patient and don't go for the full curve all at once.  It took several cycles to get it to take the shape I wanted.

[Image: attachment.php?aid=961]
[Image: attachment.php?aid=962]
I used a light coat of black paint on the hoses as a base.  Then I applied antique gold rub-n-buff for the hoses and silver metallic spray paint for the knurls.  I intentionally did not go for a prefect finish as I will be addling further weathering.

  Drive
Posted by: LarryJ - 08-08-2018, 11:49 PM - Forum: LarryJ - Replies (6)

I will be using Cary Christie's BMM/DMM for 'mounting' the head and Joe's Drive to power BB8. I picked Joe's drive because it appears that most people that have built it, have had very few issues with it. I'm also interested in Cary's drive, but it looks like it will be a couple more months for general availability and patience is not one of my virtues. Also, the cost of components is quite a bit higher than Joe's drive.

The complete drive will be printed in carbon fiber infused PLA to cut down on some weight and the increased strength.

Parts for the DMM:

Main square of the drive:

Assembly hardware (and more filament) should be here soon, so I can start putting things together.
