So I've been having fun with the Buccaneer 3d printer, making all sorts of things. You can see an album of all the random things I've printed here
Renee from the forum posted some really cool Tibia Shells and I had to take a shot at printing them with my Buccaneer and my Glow in the Dark Filament.
I tried one using the Buccaneer's auto supports, but it used a lot of material and was difficult to remove. So I took a shot at printing without supports, and I was actually pretty impressed with the results.
There was an issue with the fr side of the shell, without a support my printer just couldn't make it work. But even with the mess, I managed to clean up the print pretty well.
Since forever I've wanted to have tiny toy models of some of our robots, so one of the te things I've been working on are tiny hexapods!
Initially I actually tried printing based on some of our 3d production files for the hexapod just to see how things would work. It turned out...poorly. The thickness of the brackets wasn't enough at the scale I was making, so I had a body and tibias, but no femurs.
Eventually I brought some of the plates (Tibia, body plates) into Tinkercad and just did some basic extrusion. Even this had some issues, so brought the .svg vector files for the plates into illustrator and deleted all the un-needed holes (I left some of the signature holes, but got rid of all the bolt holes and smaller mounting holes). I used the side profiles of F2/F3 brackets and uses some primitive cubes to build some thick brackets. I was actually pretty happy with the simplified hexapod design and it turned out better than I hoped. It was still a pain to get the supports off the model, and the bottom is marred by the supports.
So my next goal in mini hexapod is to make something that is actually joint based. If I can make the body separate from the rest of the robot, then It should cut down on supports and I'll have a movable hexapod. Of course that'a all much easier said than done.
I also printed out some of the models from KevinO's Golem Hexapod. I printed them just to see how they would come out, and I certainly didn't expect them to be great ( I expected a similar experience I had with the PhatontomX Hexapod) but surprisingly they turned out pretty well.
Printing out the parts from Kevin's Hexapod gave me some ideas about how I can make some joints using rods and holes. I started playing with some idead, but I've got a bit to go bfore I've got a working prorotype. If I make the holes to small, then the slop in the printer makes it so the rods won't fit, and if they're too big, there's slop in the joint. That, and if the rods are too long, then they won't fit in the hinges without cracking.
That's all for now., more prints soon!

About 2 years ago my mother and I backed a 3D Printer called the Buccaneer on Kickstarter. We were backer #27 and paid about $300 with shipping for the promise of a printer in february of 2014. February came and went, and still no printer. Pirate3D (the manufacturer) went through all sorts of production problems, refunds, etc, to the point that there was some worry of ever getting the printer. Of course this is kickstarter, so you've got to expect this kind of thing. I wanted the printer to learn more about 3D printing, and my mom (an educator) wanted it to teach her the club kids about digital design and 3D printing. So we weren't too bothered by the delays.
We were actually really surprised when the printer finally showed up. In fact it came just in the neck of time - the next day my mom was hosting a Scratch Day Event and we set it up to show the kids. Initially I had problems with Pirate3D's Treasure Island site where you can download 3D models for your printer, but in retrospect I think it had something to do with the school's network. The generic error about not being able to download the file to the printer was frustrating, but makes a certain amount of sense. The printer actually gets models directly from Treasure Island, so it's likely that whatever method it uses to download the file was blocked. But I was able to get ahold of a windows laptop and run the Buccaneer software to load .STL files from Thingiverse
I was impressed how easy setup and the first print was. Pirate3D was really going for a simply setup machine, and as soon as I got the software dealt with, I was printing in no time.
After Scratch day I picked up some glow in the dark filament from Microcenter that is a ton of fun. I had to do some creative work to get the filament to feed into the Buccaneer since the spools didn't match, but after that it printed just as well as with the default filament.
I'm still getting used to the printer, and I've got a lot to learn about models and settings. For what I paid, I'm impressed with the Buccaneer. For a brand new one it looks like the cost is going to be around $1000. I'm not sure that I'd pay that for the Buccaneer, but we'll see after I get a little more accustomed to the printer. The printer does some things really well, and some things not so well. I need to hit up the forums and compare my results with what everyone else is printing. It would be nice if there was a base-line to make sure your printer is functioning properly. In the past I've only dealt with prints from high end machines like from shape ways, so sometimes I don't know if the imperfections in my prints are just the nature of cheap home 3D printers, or something else that I can improve. I'll have more information on the quality of my prints, settings, etc soon. Until then, here's some Print Pictures. I've also setup a webcam on the side of the printer, mostly so I can remotely see if it's still printing or not.

The HR-OS1s are shipping and I couldn't be happier! We spent the last two days finalizing the first 10 kits, but they're finally our the door. We'll have another 20 kits out this week, then the last 15 out sometime next week. I'm so excited to see how people use these robots.
I've spent the last week or so feverishly working to flesh out the HR-OS1 Documentation. I'm using Screenflow to create some cool videos that mix screen casting and video of the hardware setup. You can see them here, here, and here. I need to work on the audio - I'm using a samson mic, but I really think things would benefit from a USB headset. Regardless, Screenflow makes my workflow super easy - it even exports straight to youtube, which is stellar. I started using VNC to record other OSes, but ended up getting an HDMI capture card (the Game Capture HD, which makes things look a lot better and more responsive. It adds another layer to my workflow (Screenflow doesn't natively record from the capture card, I have to record it in another program and import it manually) but it's really not that bad (as long as I remember to hit 'record')
