Standalone Operation - Unloading Filament - 12 years ago

I've gotten to the point that I rarely have to use Pronterface with my Tantillus. Printing from the SD card is a lot easier and more fool proof than depending on having my Mac connected to the printer all the time. I can do 'almost' everything necessary from the Tantillus front panel. The one exception that I've discovered so far is unloading filament completely. When I unload the filament stops

New Tokyo RepRap Meetup Group - 12 years ago

I've started a new Tokyo 'meet-up' group for people interested in RepRap and related 3D printing. Japan RepRap, Makerbot, & 3D Printing Meetup Group We plan to have monthly meetings along with 'field trips' to events like Design Festa, Wonder Festival, and Maker Faire Tokyo. It's free to join and open to all.

Z-Axis Layer Problem - 12 years ago

I'm running into a strange problem with layers along the z-axis. If a part is relatively short - say under 30 mm tall, then the part surface is very smooth and the layers are almost indistinguishable. But, when I print a tall part, the taller the part the more distinguishable the layers become. A good (or bad) example is this Bag Handle part: It's 82 mm tall. I laid it down to photograph wit

Re: Early stages of build - 12 years ago

115200 works reliably. At 250000 I've never been able to sustain a reliable connection for more than just a couple minutes at most. Using Pronterface to setup the print and do general testing is fine. But I always do the printing from the SD card. That eliminates any possible communication problems and allows me to use the computer for other tasks, including disconnecting it mid-print. Keeping t

Re: Hexapod Information Request - 12 years ago

You're likely to run into some serious problems hanging so much weight on the servo shafts. They aren't designed for a lot of torsional stress. Typically robot designers will add a dummy shaft on the back of the servo so that the weight is evenly distributed and the servo only has to deal with rotation movement.

Re: Create a forum for Tokyo, Japan? - 12 years ago

You've done some really interesting work. I'm impressed. Any chance you would make it up to the Tokyo area sometime? I noticed that a lot of your RepRap projects were in San Diego. Will you be in Japan for a while?

Re: Tantillus Part Quality - 12 years ago

It's a pretty amazing printer. Small Treasure Chest (http://www.thingiverse.com/thing:27635). This was the first attempt and went much better than I expected. The lid fit perfectly with the hinges snapping into place. The 3D model was sliced with 150 micron layers and printed in PLA with no stringers or other problems. It did require about 1 minute of cleanup - mainly trimming a small overl

Re: Filament Holder - 12 years ago

Thanks, Here's the spool of black PLA filament I ordered from him for the camera snoot: The spool OD is 16 cm with a 3.75 cm diameter opening. The spool is just over 9 cm wide (tall?) I'll try matching that to the holder dimensions.

Filament Holder - 12 years ago

Could you post links to filament holders that will work with Tantillus? I'm particularly interested in the holder for the PLA supplied by Repraper (Simon) in China. I believe it's the same spool shown with Tantillus in the Coke Zero photo.

Re: My first steps in printable robotics - servo question - 12 years ago

Nice design, and a noble goal. I'm also excited about the extremely short prototyping cycle from idea to first part in a few hours or less. It's going to completely revolutionize design. As far as servos are concerned, it depends on the type of servo you select. The small, cheap (a relative term), hobby servos usually have nylon/plastic gears that will strip out easily. They really aren't desig
