So the Ultimaker 3 can be controlled on the local network, but are there any ideas about how to monitor or even control it remotely? Being able to see the webcam of your printer at home, while you're at work for example. I could open up ports to it in my router, making it accessible to the greater internet, but that feels risky? Or are the risks diminished by the pairing system and the fact that it has ssh turned off by default?

So there are no sensors to check filament flow right? I was hoping it could measure that it ran out of filament or even that isn't not going in as fast as it should. (I understand that with the NFC reader/writer you could potentially store the amount of filament that's left on each filament roll) You've explained where the ambient temperature sensor is added, but not why this sensor was added, I', assuming there are plans?

A forum specific question: Is there any way to follow (subscribe to) topics like Daid's Inside the Ultiamker3 series? Forum software like Discourse for example allows tagging topics and users can subscribe to tags. A way to follow certain users (the topics they start) would also be nice.

Very interesting! Small note: The diagrams appear to be cropped? Also you forgot a word or two at the end of the following sentence:

Why the "?csv=1"? Why not simply ".csv"?

I opened an issue: https://github.com/Ultimaker/Cura/issues/1084

@Render I'd love to try when you have a RC. I'll keep following this threat.

Sorry, but that really doesn't seem easy. That's like going back to the pre-ultmaker2 days, where you didn't have all this handy menu features. And also, it's not possible during a print pause, since you can't move the material for example. Btw I figured out to get the latest firmware on my printer and created a documentation pull request: https://github.com/Ultimaker/Ultimaker2Marlin/pull/116

I've installed the latest Cura beta 2.3.0 and upgraded the firmware. I added in the gcode using the postprocessing script and I tried changing the material. It now indeed asks for the material type before inserting it. But something strange happened, after I selected the material it tried to heatup the nozzle, but when it seemed to reach it it kept toggling between and This happened again after a reboot. The firmware version:

Awesome! I really like the balance between aesthetics and functionality. Have you published your work on github somewhere?

One big issue is that this isn't possible when a print is paused, for example when using the PauseAtHeight plugin. Since there also isn't a move material option there is no way to get the material flowing with the right temperature before continuing the print. I also just openend this one: https://github.com/nallath/PostProcessingPlugin/issues/19 And in general I don't think this is really user friendly...

You are totally right, I totally forgot about disconnecting the power. I should have known that by now. Measuring this again with the power cut off I got a normal looking value. I now re-soldered all connections of the screw connector and the sensor, while adding some more soldering (without moving the components) and now it seems to work. I tried heating the bed to a few temperatures and saw no strange fast fluctuations. I'm starting a bigger print to test it over a longer period. Thanks for all the help!

I looked at the connections on the bed through a microscope (awesome to have a electronics colleague) and they seemed fine, but I re-soldered them anyway. After heating the bed to 85 degrees (and seeing the temperature suddenly jump to 100 and back again) I noticed that the resistance directly over the sensor was 4,6 MOhm, which seems like a crazy amount. I re-checked my multimeter with a basic 220 ohm resistor. I think I'll try to get my hands on a new PT100 B sensor. Comparing it to the Adafruit Ruler it seems to be the 805 form factor. If someone has a Farnell / ... link ready that would be really awesome.

Ah alright, so that resistance seems okay, I measured 112.4 ohm. I'm not sure about the wiring, I actually measured the continuity of he wires on the bed pcb, even while trying to move the screw terminal.

Does anyone know which sensor is used on the Ultimaker 2 bed? I couldn't find it in the opensourced files: https://github.com/Ultimaker/Ultimaker2/blob/master/_BOM/BOM%20ultimaker%202.pdf https://github.com/Ultimaker/Ultimaker2/tree/master/1155_Print_Table_Heated_Bed_(x1)

Hi folks, We're having an issue with our Ultimaker2's heated bed. When we attempt to print we get the flowing error pretty quickly: When we just heat the bed from for example 60 to 90 degrees we get the same error. When I tried this again (heat it to 90 degrees) I saw the temperature suddenly jump from 75 to 120 degrees. We checked the following page: https://ultimaker.com/en/resources/19485-error-stopped-temp-sensor-bed A few observations: - We of course checked if the cables where properly connected, seemed so. - Visually there seems to be nothing wrong with the sensor or the connections going to it. (I'm assuming the sensor is the white SMD component) - We disconnected the cables and checked the cables them with a multimeter, even when moving them, they seemed fine. - We checked (with a multimeter) the connection between both sides of the sensor and the screw terminal on the bed, seemed fine. - Cooled down the resistance over the sensor was 112.4 ohm. - After switching around the bed (TEMP3) and nozzle (TEMP1) connectors in the main board: - When we just heat up the nozzle the temperature sticks to 30 degrees and we get an "Error - stopped heater error" pretty quickly. - When we just heat up the bed it shows a lowering temperature from 45 to 29 degrees (the nozzle was cooling down from the previous test). In the end it shows: "Error - Stopped temp sensor". Is there anything else we could check? What could be the problem? Thanks in advance!

http://doodle3d.com/hackaton/ On 22 march we invite you to Utrecht (Netherlands) to control 3D-printers with your favourite programming language! The Doodle3D WiFi-Box makes almost all 3D printers wirelessly controllable through a simple REST API. This means you can control them using Processing, openFrameworks, JavaScript, Arduino, Cinder etc. Basically any language that can send and receive HTTP requests (ajax). So what could you make? You can think of the Doodle3D drawing application as the first application written on top of the API, it makes 3D printing a simple sketch child’s play. Another example is Cura, which uses the API to enable wireless sending a print to your printer. But using the WiFi-Box you could control a printer using a Kinect, do something with sound input, maybe make a creative cup designer or adding an embeddable print button to an existing design application or website like thingiverse or youmagine. Admission is free but registering essential so that we can do groceries. Please bring a laptop and a 3D printer if you have one. We’ll have enough Doodle3D WiFi-Boxes available during the day. More info and registration: http://doodle3d.com/hackaton-en/

No tips on where I could add a 5v power plug on the Ultimaker board?

Hi guys and girls, I've had a lot of fun today using the new Wireless printing function in Cura using my Doodle3D box. (I'm one of the developers, please don't see this as a plug) http://fablabamersfoort.nl/fotos/index.php/24-Dec-2013 I'm curious if it would be possible to power the box from the Ultimaker, so I don't need a separate power plug. Looking at the electronics (we have the 1.5.4 version) I see 3 interesting spots: - top left, 5v and gnd - bottom left, 5v and gnd - middle, exp4 (didn't have a change to measure the voltage there) - left, in the screw terminals (didn't have a change to measure the voltage there) http://www.reprap.org/mediawiki/images/7/79/UltimakerPCB1.5.4-prototype.JPG What do you guys think? Seems important that the box doesn't influence the function of the Ultimaker electronics and the other way around. Also being able to make it pluggable is a plus. Thanks in advance

@ Daid, Maybe some of these links are useful, if someone wants to implement support in Cura http://www.doodle3d.com/help/wiki/makerbot

We are working hard of having a kind of printer profiles system. So that for example the ultimaker2 can have specific start and endcodes. https://github.com/Doodle3D/doodle3d-client/issues/85 As well as on that DHCP issue: https://github.com/Doodle3D/doodle3d-client/issues/66 I can't wait until I can print regular prints wirelessly trough the boxes using Cura Let us know how it all works, we of course mostly hear about the problems.
