UPDATE2: Found another bug... a known one I thought it was already fixed.
When doing a one-after-the-other print of two objects with brim, for the second object it begins somewhere in the middle of the brim and first goes inwards then completes the outermost lines of the brim.

UPDATE: I just found something quite serious:
Did you change the EOL-character in the generated GCODE? It's now kind of a mess on a Windows machine (everything in one line). And the TweakAtZ plugin was not executed at the layer I specified (I will have to check the GCODE on the SDCard after the current print finishes, on the PC, the GCODE includes the TweakAtZ information); this might be related to the EOL character.
EDIT (10:37): Forget about the plugin, it works fine if a reasonable input is made... :shock: (means: my fault).

Hi Daid
The speed of the new layer view is amazing!
I have one thing you may want to consider. But it's not related to the GUI, so you can move that to a later version if you like.
The flow percentage in the basic settings tab directly affects the amount of filament used with the E-argument in the G1 lines. Right now there actually two inputs (flow percentage and filament diameter) which scale the amount of filament used in Cura.
However, as TweakAtZ is now part of the package, it might be an idea to let Cura insert a M221 instead of changing the E-argument directly. If it's done in this way, then e.g. 90% flow in Cura would correspond to 90% in the TweakAtZ plugin. What do you think?

I need to stop bouncing between tabs and reading different things while replying to topics
Unless you are a woman. They can do that. At least they pretend to...

So it comes back to cooling of the UM board. Although it has a powerful radial fan, the fan duct is quite - uhm - suboptimal...
Just for completing the picture: The other way round (12V instead of 19V) shouldn't be a problem? As I will (hopefully soon) implement my heated bed with a 12V additional PS, it might become a topic for me to reduce to one PS.

It seems to work again - I just uploaded successfully three pictures...

What I did to test qualitatively for backlash was to push and pull at the print head with steppers ON. Not with brute force of course. Ideally you should not be able to move it when applying reasonable force.
The other test you can do (if not done already) is to push the print head around with steppers OFF. You should be able to push the head with your little finger. If you're not, then at least one of the long belts is too tight.
I don't have the short belts anymore due to direct drive but I remember having the tension of the short belts in the range you just described; they should be ok.
If you got your UM Original as a kit, you may have received some silver colored grub screws. They are replacements for the black grub screws of the pulleys and are supposed to give a tighter grip if I'm not wrong. If you haven't replaced them, it might be a good time to do now.

Ok, now I'm getting it as well. I just created a private album and was not able to upload images to it. I've contacted Ultimaker about it.
Thank you!
disk full?
Probably...

Ganz so schlimm wie links in dem Bild war es zwar bei mir auch ohne direct drive nie, aber das rechts ist schon das Resultat.
Kegelzahnräder wären durchaus eine Variante, da sie wenig Spiel haben. Allerdings müssten sie vor Staubablagerungen geschützt werden, was wiederum etwas problematisch mit der Abwärme der Motoren wäre (im Fall, dass die Abdeckung um Zahnräder und Motoren herum geht).
Ich möchte in Zukunft ev. auch das ganze Bauvolumen zumachen können (Stichwort heated chamber). Spätestens dann müssen die Motoren dann ausserhalb des Druckers sein weil sie sonst zu warm bekommen.
Und Du hattest ja nach einem Bild meiner hässlichen Schönheit gefragt:
Ach ja, falls Du Dich fragst, was der UM gerade auf dem Bild druckt:

Still not working here...
edit: @Robert: Maybe some authorization issue? You certainly have different permissions than other users...

Thanks for confirming!

Has anyone recently uploaded any image to the gallery? I just get a server error message... for any picture, with both uploaders, for Firefox and IE (yes, if you're very desperate, you even try IE...)
edit: I was able to create new empty albums...

Sounds very promising... :-P

Also bei mir bringt der UM1-Direktantrieb extrem viel, nämlich eine hervorragende Printqualität. Ich hatte vorher immer mit den kurzen Antriebsriemen gekämpft, das ist jetzt vorbei. Und seither werden die Löcher einfach rund.
Aber Du hast Recht was das Aussehen angeht. Mein UM1 sieht im Prinzip inzwischen extrem hässlich aus. Mich stört das nicht; ich will ein Gerät, das Top-Ausdrucke macht und keinen Eye-Catcher (ganz nach dem Motto 'Schönheit liegt im Auge des Betrachters'). Aber die Anforderungen sind natürlich nicht bei jedem gleich...

Sorry, I didn't see Ian's post when I wrote mine...

If the diameter of your filament is close to 3mm, I may check if there is more friction in the Bowden tube when the print head is at the 'underextrusion site'.
-
Daid, you probably want to shoot me on the moon after reading this post...
But: What about creating a completely new settings tab for dual extrusion? I guess dual extrusion has some future, also with the UM2, hasn't it?

I dry in the refrigerator the PVA during 3 days[...]
Hmmm... I think it's not especially dry in a fridge. I would rather put it in a (convection) stove and heat it a reasonable temperature (40°C?).
-
Great Idea !!! And i proposed to do the same thing with the retraction. I print occasionaly with my dual extruder PLA and FLexible PLA. And I have to desactivate the retraction for the both because the flexible doesn't like that. It could be great to keep retraction activate for the normal PLA and desactivate for the flexible.
Until Daid has maybe implemented it (I guess, this won't be today or tomorrow), this could be achieved with a plugin...while changing infill percentage is hopeless for a plugin.

I don't know about the prisons in the Netherlands but in Switzerland prisons are more than full and nobody wants to keep prisoners longer than necessary.
This system in Switzerland has actually nothing to do with profit. The work these people do part of a program to keep these people mentally as healthy as possible by giving them some adequate work to do. It's true, they do not make a lot of money but it's enough that when they receive it after maybe 20 years it is a good starting capital back in the outside life.
-
If you rotate the object by 180 degree, does the underextrusion then happen on the other side?
-
It's really a strange kind of behavior.
I just made a quick test with my UM1 with two simple objects 'one at a time'. The GCODE (sliced with Cura 14.01) included the retract and priming command as posted above. The UM performed both retract and priming when changing from one object to the other. It's the same directly via USB and via SDCard/Ulticontroller.
Do you use the standard Marlin or a personalized version?
-
It's just a very quick thought: Can you exclude that you are in relative positioning mode (G91)? Because then it would make sense that only the retract but not the priming command is executed...
-
It depends of the speed of the first layer. I usually print the first layer at 220°C with 20mm/s and without fan. But 210°C should work as well (I just see quite a difference in adhesion between these two temperatures). If you have an UM1 and had the fan running during the first layer, you might want to check if the fan blows onto the nozzle?
Sometimes purching the nozzle, e.g. extruding about 20-30mm of filament helps as well... And if one has at least part of the original end.gcode one should be aware that it does a retract at the end which could result in stammering at the beginning of the next print.

The new Makerbot Replicator has one clear disadvantage and that's the build height of 6 inches. That's the only thing Makerbot cannot improve over the next one or two years for the very same model.
The Smart Extruder as they call it can easily replaced. Even by a dual extruder if they develop one. Or by one capable of printing ABS. It already has a heated platform and to add an enclosure should not be that difficult.
But some people here in the forum are currently working on a swapable extruder even for the UM1.
Another feature of the new Replicator, the out-of-filament-check, is also very nice. I think a future product from Ultimaker may also include such a feature. But it would be even better if the printer would not just realise when it has already run out of filament but a few meters before (I now that's going to be difficult but hey, this is the UM forum where the (nearly) impossible is made possible...
).
About the UI knob they are so proud of: Have a look at the UM2... :wink:
