If you search 'Olsson Block' you still don't get the original post from Anders Olsson on the first result page. If you search with Google including 'site:ultimaker.com' it's the top result.

That top part just came in time! I'll use it quite soon...
-
Non-US users who want that kit should check with their 3dSolex representatives; some of them have it available as well.
-
Can someone tell me where to get the SelectExtrude plugin and how to download it? I went to GitHub and I do not see where to download the py file.
Can someone just send me the file or post it on Ultimaker so it can be easily downloaded?
Thanks
Bob
Well, the 'download here' on the Wiki page is not that extremely hard to find, isn't it?

@oceanblue72, @3Dimensionen: Das Problem der höheren Drucktemperaturen kommt i.d.R. von einem schlechteren Wärmeübergang von der Heizpatrone zum Olsson Block und von diesem zum Temperatursensor. Ein gutes Mittel zur Abhilfe ist z.B. Kupferpaste um den thermischen Kontakt zu verbessern. Ich selbst konnte damit tatsächlich eine Reduktion der Drucktemperatur (mit Original 25W Heizer) erreichen. Am besten überprüfbar ist eine Veränderung der Drucktemperatur mittels der optimalen Temperatur eines Cold Pulls.
Beim Olsson Block muss man aber auch unbedingt darauf achten, dass kein thermischer Kontakt zwischen dem Block und dem Lüfterblech besteht; ansonsten fliesst da schnell mal einiges an Wärme ab und die Drucktemperatur muss erhöht werden.
Zuletzt ist aber doch auch noch zu erwähnen, dass es bei den PT100-Sensoren von 3dSolex einzelne gegeben hat, die im hohen Temperaturbereich deutlich abgewichen sind. Falls Ihr denkt, dass Ihr einen solchen habt, setzt Euch doch bitte mit dem 3dSolex-Vertreter in Verbindung, bei dem Ihr Euren Sensor gekauft habt (bzw. mit 3dSolex falls direkt gekauft).
@avogra: Ja, der I2K funktioniert prima mit PLA. Du meinst vermutlich den IPM-Isolator, der nur für ABS geeignet ist.

-Search, I still use google, since the in site one just doesn't work. The new users, the target audience of this whole overhaul, WONT. They use the site search and can't find what they are looking for. Either they give up(you lose them), or they post ridiculous topics with questions answered ten times already(you lose power users).
My advise: replace the search with a google in site search until yours actually works. It's fugly as hell, but atleast it works.
...
A very good advice IMHO. One that UM should declare their top priority for the forum.

Oops... I should have mentioned that I use copper paste not thermal grease. It's suitable up to 300 °C.
-
Yes, I recommend it. It's never wrong to have a good thermal contact between a heater, a heat conducting element (heater block) and a temperature sensor.

@anders-olsson: Thank you for those honest words.
It's not only the forum.
For me, there are multiple things wrong at Ultimaker. This is a very subjective view but my impression is that Ultimaker has drawn red lines beyond which they do not care anymore about the users. That's actually not something unusual but it doesn't match the claim to be very customer friendly.
The fact, that Ultimaker has stopped selling directly is understandable from an economical point of view and in a few regions it works well. In others it doesn't. At UM HQ they sometime simply don't seem to know the whole distribution chain to their users. While in a recent interview the CEO and the CTO tell they don't want their machines to be sold by boxmovers it seems as in quite some countries, including their home market, exactly this happens. I'm aware of FabLabs and schools, which belonged to the first Ultimaker customers, which are pissed off by the fact they now have to buy parts significantly more expensive from distributors and resellers (some of which are really not 'makers at heart') and have to use expensive hotlines to get support instead of the old UM support. Can you blame a company leaving their first customers in the lurch because of concentrating on more and higher paying customers of more recent products? No, you can't. It's economically the right thing if you have to choose. But it's betraying the origins of the company, isn't it?
At the moment Ultimaker may have the best in class machines (but also one of the most expensive) and sales might be excellent. However, more and more small companies use those machines and at some point they are disappointed because they expect at least semi professional constructions but it's not (even UM2+ are home machines, not pro machines). However, it seems at the moment UM wants to go further into that direction judging from recent marketing.
Within the next few years, the market for desktop 3D printers will change extremely. Pro machines will become cheaper (don't forget e.g. HP to enter the business) and the 'cheap' products get better every day. The air will become thin for Ultimaker.

Hi,
As far as I know there will be a +kit available soon and you can do it by yourself (it would be pretty ironic if Ultimaker known for its commitment to its users would require them to have the printer sent in to do the upgrade...).
Well, so far UM only announced an upgrade kit but didn't explicitely say it can be mounted by the user in all cases (what happened to the discussions about CE conformity?). And even when Ultimaker promise something we all know it does not always come true...
-
That's the Ultimaker Wiki... an abandoned project...

Das Hotend muss aber auch auf 1.75mm angepasst werden, sonst blockiert das aufgeschmolzene Material das Rausziehen. Das heisst dann Filament einmal drin, immer drin.
Dazu gibt's u.a. den Olsson Block mit TFT Isolator für 1.75mm.
-
@niyoki, yes.
-
Ah... that's the glitch with SelectExtruder Plugin. You first set the temperature (on the first extruder!) and THEN the plugin - which runs after slicing - selects the extruder.
-
Hmmm...that's interesting. Can you please put your gcode somewhere and post a link to it? It it's not to disclose, you may send it to me in a PM.
What Cura version do you use and what type of machine have you defined within Cura? Do you have any dual extrusion option activated?
-
I achieved 13mm3/s with a 25W heater inside my OB. But I used copper grease to improve thermal contact. A 35W heater does the same job as the copper grease: it increases the flow of thermal energy into the OB.
-
There is a plugin called SelectExtruder for legacy Cura...

@Herbert: 3dSolex hat auch diverse Länder-Vertreter und die sind recht schnell...
-
If you have a bad temp sensor from 3dSolex please get in contact with your 3dSolex representative or with @swordriff himself if you bought it directly from 3dSolex. The bad temp sensor will of course be replaced.

How many dots are on the nozzle?

An meinem UMO habe ich jeweils die ungenutzte Düse leicht abkühlen lassen. Wegen der starken Wärmeausdehnung beim UMO Hotend führt das auch dazu, dass besagte Düse nicht anschlägt. Rausschrauben ist keine gute Idee beim UMO; beim UM2 würde ich sie wahrscheinlich auch rausnehmen, wenn ich nur Einzelextrusion fahren möchte.
-
@Giddi: If not, you still may use the Korneel spacer...
Both PTFE couplers are of high quality. 3dSolex 'certifies' their TFT to be used at 255°C continously, together with the I2K even at 300°C continously. Mayby we will soon see a similar statement from Ultimaker.
-
@foehnsturm: In general you're absolutely right. But keep in mind that Ultimaker still claims 'we are makers at heart'. Focussing on an even more pro user market would somehow not fit that slogan. But maybe they will drop it this year.

... looking at the CEO statement they must be close enough to be confident to state "this year".
I would not take this statement for written in stone. If they see that postponing an announcement date makes sense they certainly will. Example: UM2 dual extrusion was postponed more than once before it was cancelled.

Sure. But only when it is finished...
