Did that solve it? Mine are dropping out after 48 hours

I have that issue on the Ultimaker 2+ and always do the Move Material function prior to a print to prime the print head.
On the Ultimaker 3, I have only had this happen once, even with the latest version of the firmware. I'd re-check the firmware for the latest. One the 5 prints I have done so far on the UM3 I have here, it's only done this once. (I manually moved material on each nozzle then did the print.)

Erin saved the day
She advised the calibration process for the nozzle switch
The first time thru, it didn't work. Did it again and now it is working great.
Did a short test print and that worked! Doing a long, 21 hour print now to really test it out! So far, so good

I have an Ultimaker 3 on loan to me for an upcoming show in two weeks.
So far, this printer is having a hard life here. There's been a few issues since unboxing and unfortunately, there is this problem too....my PLA/PVA prints are getting knocked over.
The first one happened last night and when I awoke, I have a mess of "spaghetti" all over the printer and a knocked over print. I blamed the usual suspects...poor adhesion. So I applied a coating of diluted PVA glue to the bed and let dry. I've used this method on my Ultimaker 2+ and had no troubles with adhesion since. Just to be double sure, on the next print, I selected brim.
The second print (bird in a birdcage model), is a 13 hour one. I monitored a portion of the print remotely and went to bed. I woke up hearing some loud noises from the printer (from upstairs!) and recorded what the printer is doing.
The entire bed moves/bounces as this is going on.
If you watch the video closely, it looks like the PVA nozzle isn't retracting and colliding with the structure while the PLA nozzle attempts to apply it's layer.
The previous model was a thin one, the seahorse, so if this happened on that print, I can see it easily being knocked over.
Any idea how I can fix this? (The printer does have the latest firmware installed)
-
Correct, didn't even have a web browser open
-
It's wifi
I am also using the default, "Recommended" settings to print the Seahorse with PLA and PVA Both attempts, the print head knocks over the print.
Thus far, I'm still waiting for the fun to begin

I've had pretty decent luck with Cura 2.5 on my Ultimaker 2+ and am trying it out on the Ultimaker 3 now.
One think I am noticing is just going between the tabs for the nozzles, I get long pauses of "not responding" and some really, really slow performance within Cura. Is this related to the networking to the printer?
I haven't seen pauses and hangs like this with the UM2+ and this laptop is pretty fast.
Anything I can do to remedy this?

We've discussed this topic a good deal
I still think it should be disabled by default

I've used Testor's Model glue in the past...it's so, so stringy tho, so clean up is important.
-
I was looking at the instructions and kept looking for some subtle warming about alignment of the magnets North or South
-
We've all heard it...the rumbling and grinding sound as Cura's default settings (Combing Mode All) mashes the nozzle against the print, making the print bed bounce and just, generally, not good
Can you guys please, please fix this? It's so annoying.
I find myself using Simplify3D more and more as Cura does things like this.
If I set Combing to Off, I get an awful finish.
Please don't tell me I need to set z-hop or any other crazy things.
Honestly, Cura on default settings shouldn't perform so badly.
-
Just a quick note...something I discovered and might apply to others...
I went into my Notification Settings and figured out why I wasn't receiving alerts on 3D Prints I had posted. They were off
Maybe a default setting?Now that I have those set to my preferences (immediate and email), I am not being alerted to when someone comments (or likes) a 3D Print I have posted

That would be a nice thing to have, especially for those who are more professional users and less into tinkering.
For example, I know that my Colorfabb PLA/PHA tends to work best at a higher temp than Ultimaker brand. With the Ulticode, I can't set that in Cura. I have to do it manually on the machine.
(I would advise a materials.txt import of a ColorFabb filament, but I believe that system is not working reliably)
Or...if there is a way to add a filament profile within cura in the future, that would be superb. This way, if I recall the settings I used for another filament type, say ColorFabb nGen or ColorFabb XT, I could have those known-good settings imported and ready to print.
Just thinking of a way to make it easier to print with Cura.
Obviously, in Simplify3D, you set everything manually but you can create a profile for it. Which makes switching to different filaments very easy.

I like Crash Test, he's very much how I like a review....blunt!

It's on eBay

Good day,
I was curious if the newer version of Cura had material profiles for PLA makers besides Ultimaker. When I went into the pull-down menu, I saw pretty much what I expected. (I had hoped to see material profiles for the ColorFabb PLA/PHA filaments)
What surprised me was when I changed my printer to the Folger Tech FT-5 and when I clicked on that material pull down menu, many more options appeared.
Now two questions...
1) Why do those materials not show up for the Ultimaker? I am guessing it is because they are 1.75mm
2) When will material profiles other than the Ultimaker brand appear for Ultimaker printers? (And how can a user manually add that?)
Colorfabb and Ultimaker have been a really good combination for a very long time. I'm really surprised that's not in there!

The printer has been sold and has shipped off to it's new home in sunny California
-
Those are such neat machines, just wish it came with a heated build plate
-
The outer part of the part looks good. The inner is awful. Lot's of marks and underextrusion going on. The surface finish is ugly.
Underextrusion is most often a hardware issue. It could very well be that this problem coincidentally started when you started testing Cura 2.5. Please try the standard methods to try and resolve the issue on your printer.
Time for an atomic pull (or two)
-
What if the models are large, so two do not fit within the printable region?
-
Print completed...first one with this Beta 2.
As with the noted rumbling sounds, some other issues
The outer part of the part looks good. The inner is awful. Lot's of marks and underextrusion going on. The surface finish is ugly.
Asides the suggestion of Combing Mode to Off...how else could this be improved? The wall thickness is 1.2 mm, so I am guessing that made it hard for Cura to adequately compensate of Outline Overlap (as S3D would call it)
Also, please check out the prongs and how between each, this is a tiny support structure. It isn't supporting *anything* and there is no way to remove these.
Please please...give us the ability to remove and manually add support where needed

Well I hate to say this....it is still happening
I just finished an 8 hour printer (from Cura) and went to start another print. After the print started, it did the usual priming but nothing came out. I left it alone and by the second skirt pass, i was getting little dots and finally some material coming out. I aborted the print and went in Maintenance on the Ultimaker 2+ menu and Move Material.
Here's the last section of gcode for that print if it helps at all?

There's no chance you are over-extruding and the infill is coming out a little high, is there?
No, usually I am quick to fault myself but my UM2+ has been doing some really really good prints lately. This one just surprised me with the grinding noises. First print using Beta 2
-
Combing Mode Off for that? That's interesting.
I just don't understand why the default UM2+ profile would require that disabled.

My PC anti-virus screams if I try to install this Beta. Has that been fixed so I can try again?
