TLDR: the guys that I caught showing heavily processed prints from different types of machines and claiming them as unprocessed prints from theirs at NYMF have now been caught ordering prints from Shapeways for the same purpose. I predict this will be the new Japica.

Other than the Paizo forums, does anyone have a good source to find PBP (play-by-post) games to join? I'm looking for a game that I can play a little every day, rather than fighting with a group to schedule a time.

BTW, I'd rather it not be a PFS thing, because that can tie up a character for a long time. Also looking for something RP-focused.

We now have up the video of +Whosa whatsis  and my  Hackaday Prize entry. The project is to find people who like making models (or who have a student or community hackerspace looking for a project) to make models that have been requested by teachers of the visually impaired. Many of these teachers have 3D printers, but don't have the time and/or expertise to create the models they need. Project video: https://www.youtube.com/watch?v=hlxvQ7lgT14&feature=youtu.be

ust got my copy of our new book (with +Lyn Hoge and +Whosa whatsis), just in time for NY Makerfaire! We will be at the Apress booth at 11 AM both Saturday and Sunday if you want to come by (in the Maker Pavilion, Area 3, middle of the tent somewhere.)

Looks like Full Spectrum beat Glowforge to market with an incredibly blantant rip-off of their design.

We (+Whosa whatsis and I) are teaching a free workshop on makertech for teachers, sponsored by National University. It will be at their Spectrum location in San Diego the morning of Saturday Jan 14. One hour overview lecture of all things maker, then an hour of small-group demonstrations.

Answers to the questions I had going into the Ultimaker 3 launch event (plus a few surprises):

The nozzle lift does not require an extra motor. The left nozzle is fixed, and the right nozzle drops below it or lifts above it using a switch on the side of the effector, and there's a piece of plastic on the side that the it runs the switch into to toggle it (judging by the force needed to switch it by hand, it's probably close to the stall torque on the Y axis).

The OLED display does appear to have been replaced with an LCD, for some reason.

The construction is almost identical to the UM2 aside from the effector. It looked like it might have been built out of different materials because of the lack of black dibond edges, but it's the same material with a white core. They did, however, remove the indentations from the top that allow the machines to be stacked.

The Matterhackers guys said that they're still using the same old ultimaker controller boards (still no 32-bit), but have added a single-board computer (Raspberry Pi equivalent) running linux to handle the networking, flash drive, and camera. Camera images are retrieved by Cura using an HTTP request, so it will be easy to set up something else to monitor them.

Nozzle height is calibrated with a capacitive system (most likely measuring the movement of the nozzle/heater block when the printcore spring compresses).


Everything but the print cores was a bit underwhelming, and I would rather have seen those as part of the UM2+ upgrade (probably the only reason this didn't happen was because of the added wires needed to connect to the new components).

Between this and the proliferation of multi-input-single-output bowden systems, I think 2017 will be the year that desktop multi-extrusion really catches on.

Right now this is the case indeed. I think it's one of the main points of criticism from the last round of beta testing on the hardware side. I think the cores are going to cost around $100. (but don't quote me on this one, I could be wrong)

On one hand, it's a lot quicker to change a printcore then a nozzle. But it is also more expensive in the initial buy. I've heard some hallway talk about maybe making a core with screw-able nozzles like in the UM2+. But those are just random ideas, nothing has been decided on that area yet.

The nozzles are part of the heater block, which you can unscrew with the proper instructions. However, if you do it improper you will damage or break part of the hotend. So that's not useful if you want to swap often. Note that the UM2 (not the UM2+) has the same issue.

Excited to hear that +Whosa whatsis and my  #HackadayPrize2016 project has been selected in the Assistive Technology round. Now our project moves on to final round of judging. The project is about creating a community to create 3d printable designs to teachers of the visually impaired. Please take a look if you want to help! (project link: https://hackaday.io/project/11312-3d-prints-for-teachers-of-the-visually-impaired). Thanks to all who helped already!

General discussion  - 
 
I saw some pretty implausible things being show in the 3D printer village this year.

The first one I saw was a 3D metal printer made out of a MIG welding rig and a milling head on a 3-axis cartesian bot. It was enclosed in box that was supposed to get filled with an argon atmosphere, but didn't even have weather stipping to keep it from flowing out (and air flowing in). Worse, it had big window with nothing but a clear plastic sheet. This machine had obviously never been turned on, or someone would have gone blind. When I pointed this out, the builder said that, yeah, we should probably replace it with something tinted. He then said that he wanted it clear so that you could watch the milling (which was supposed to happen each layer), then realized that if he tinted the window, he would only have to turn on the RGB LED strip, apparently not understanding the difference in brightness between indirect light from low-power LEDs and a welding arc.

The second was a printer from http://next-dynamics.com/ (which claims "Print thousands of different materials and colors with a single print", despite only having 3 inputs) that was supposedly jetting resin like an Objet. This printer supposedly had multiple materials (including a conductive material) fed from cardboard boxes with nozzles sticking down. The guy running the booth swore up and down when challenged that all of the prints he was showing (most of which looked suspiciously similar to Objet prints I've seen in the past) had been printed on that machine (which, unsurprisingly, was not running). One of the pieces was even chipped, so I could see that it was definitely made of resin. One of the prints, though, which he repeatedly confirmed was an un-postprocessed print from the same printer, was clearly an FDM print that had been acetoned to within an inch of its life. This was the common treefrog print in two colors, which I knew very well would not look like what he was showing if printed the way he claimed to have done it. The print had also broken in places, revealing FDM infill (something that I'm fairly confident is impossible with resin-jetting), and there were a few other classic FDM artifacts that were. I pointed out the infill, and he doubled-down by claiming that it (including the top-surface bridging over infill that was slightly visible through the translucent filament) could be done with his process.

Yeah, that much has been done before. http://www.appropedia.org/Open-source_metal_3-D_printer

It is, however, much more difficult than this guy obviously realizes, and there are a lot of other problems with the claims he's making.

Ultimaker now has a Cura beta that supports other machines. Hope it's not the unusably-buggy mess the original (non-beta) version of Cura 2 was, if only to justify the fact that they replaced the link to the old (working) version of Cura on their download page with it.
 
If you want to be on the cutting edge of slicing software, now is the time to try out the newest Cura 2.3 beta!
We are always working with our customers and community contributors to bring you the best in 3D printing hardware and software. And today, we’re excited to present you the new Cura version....

+James Newton We re-wrote the whole frontend (as the old code was a mess), which this change we changed how machines where handled, so we initially only had Ultimaker machines in the first version, as those where the machines we had access to.
This list is now growing as more and more machine definitions are contributed.

The old (legacy) Cura had support for a lot of machines. So this made some people confused/angry.
