Just, noticed that it does not work with multiple objects.
I am working on a fix for this problem.
Edit: Okay, multiple objects work with the first version too. But there will be a display error.
I think it works also with the UM2. For this, however, the GCode Flavor must be switched to REPRAP. Because with the UltiCode there is no command to print a message on the display.

Hello,
I've created a plugin today which displays the current Printlayer on the Ulticontroller. It works with the UM1 and the Ulticontroller so far. I don't know if it also works with the UM2, since i don't know how the display on the UM2 works.
Can someone test this?
I have created also a small wiki page where you can find the plugin.

If you have problems or questions just ask. It is my first python program.

Great.
You have ok convinced me. I have bought a kit for myself now, too. But unfortunately, no more Glass kit was left =(. Now, I have only a heated bed without glass.
Will you offer them again? JasonHK?

Has anybody recived the bed from Jason HK?
Or can someone report about it? I also want to buy one in the next few days.

I think installing Eagle just to open a schematic, create a PDF and uninstall Eagle again is a bit exaggerated. A PDF like this i found on the internet is very pleasant to the read as I find. http://www.mikrocontroller.net/attachment/215027/Copter00.pdf
But this is only my opinion.
Back to the topic...
It looks like the Connector can deliver enough current to drive two strong fans. If the transistor gets to hot it can easily be replaced by a small FET.
Hm, 47dBA is really noisy.Have you thought about that well?
My sample must either be buried deep under the ground, or in a well insulated enclosure. :???:
I think with two units: nearly 10CFM / 8.000RpM / 35dBA; are more than adequate.
Another example:
Everflow R124020BM 12V DC (Range: 7~13,2 V)
40x40x20mm / 3-pin Molex /2 Ball-Bearings / 8000 RpM / 34,8dBA (max. 37,8dBA) / 10,19CFM (0,29m³/min) / 1,20W (max.1,92W) / 0,10A (max.0,16A.

Hmm yeah that's true. 47dbA are pretty noisy.
This model looks also very good. Yes, I think also 10cfm per unit should be enough.
You shouldn't use two 40x40x20 mm fans. That's a lot of weight for the printhead.If you really need to do that, you will probably have to print very slowly in order to prevent having problems with ringing or even skipped motor steps.
It seems most 12V fans don't have a problem with19V supply. I'm using a single Noiseblocker Blacksilent fan, 40x40x10mm, with very low airflow (same duct as mentioned above, but only left side part). Works well enough for my blocky technical prints.
I always print at 35mm/s speed. Takes long, but usually gives good results.
If 2x fans are too much weight for the printhead. Why are there so many designs for 2 fans? The datasheet says 30g for each fan. So with the fan duct approximately 70-80 g more. Is this to much for the motors?
I want two fan because, for example when I'm printing the UMRobot. One side is a little bit better than the other.
Yes the most fans operate without problems at 12V but I simply don't have good feeling if I operate a fan over the spec.
-
O.o this isn't an 12V Connector?
I have installed the Altium Designer. Therefore I do not necessarily want to install Eagle.
I would be you thankful if you could create a PDF.
Thanks for the tip with the Evers fan. This one does not look bad.
Now I have to look only if I can get this one in the Switzerland.
I'm thinking about designing a small adapter board to convert the 19V to 12V. With this Board I would control then 3 pin fans so that the thermal sensor is not disturbed.

Hello,
I want to mount two 40mm fans at my ultimaker original. I printed the fan duct which you can see at the end of the post. As far everything is alright. But today when the fans came and I tried them, I have found that the air flow is very low. I bought these fans:
Scythe Mini Kaze SY124010L (40mm)
4,11 CFM = 7 m³/h
Preasure
2.13 mm H2O
Voltage:
12 V
Current:
0,06 A
Is that enough airflow for cooling the object? If not which fans could you recommend?
I think this one is a little bit overkill:
My last question is: How much power does the fan connection deliver? I have no Eagle so i can't see the schematic of the controllerboard. Could someone please create an pdf of the schematic? This would be great =).

Hello,
I have recently noticed, that the temperature of the extruder hesitates extremely as soon as the ventilator is switched on. But only if the fan is not completely switched on. If I turn the fan completely on(255), the effect disappears. I tried to make a video in which the effect is visible.
Is this normal?
Greetings

Today I printed my first modelled object itself. It's not as awesome as your prints. But I think it's still ok.
I've published it on youmagine if someone else wants to print it.

Okay now it worked.

I've got my filament from faberdashery today. Printing without a spool doesn't seems to be a problem. But how do you store the filament? I think, if I simply put it in a bag without any spool, there occur many knots.
