Ah wait. We noticed this problem a while back (CURA-3037), but it seems only a problem for Windows users and then the bug got lost in a large pile of bugs which we never got around to looking at again :S

Haha, ok. Oh wait you said you have an Ultimaker 3. Nvm. Ah this is about material profiles. Maybe @nallath can help you out here? This seems to be a visualization problem, which is also present in Cura 2.5-beta!

I don't understand. You only need to move the model down 2 layers - not 15. There is no upper limit on how much you move something down. You can just fill in numbers in the move tool window.

The prime positions have been changed to the sides. Yay!

Sounds like a good use for having a camera! Note that the build plate also moves up and down when switching nozzle, though.

What printer did you select? Did you try closing Cura and starting it up again?

Which version of Cura were you using? If it was cura 2.5 beta, please download the latest beta. Please share your gcode and project file.

Cura 2.5 definitely handles positioning differently from 2.4. Since Cura 2.5, CuraEngine is using multi-threading to speed up the process. The engine generates multiple layers at the same time. The major disadvantage of this is that the engine doesn't know where the previous layer ended in order to get the point on the inner walls closest to the previous print head location. Instead the engine starts each layer closest to the Layer Start Location. A workaround for your situation is to set the Layer Start X and Layer Start Y to the same values as the Seam X and Seam Y. I don't think this is a problem for most prints, since most prints use infill, so the starting point of the inner walls is already closest to the last infill line, rather than the end of the outer wall on the previous layer in both Cura 2.4 and 2.5. Moreover, we think that having the location of the seam of the inner walls at a different location as the seam of the outer wall could help strength prints and reduce the size of the z seam which is visible on the outside. Love to hear your thoughts.

Please try printing over USB. We've had an issue with printing over the network which we fixed a couple of hours after we put beta 2 online and then we refreshed the beta 2, so it might be the case that you have the wrong beta 2. You could try to re-download beta 2 and reinstall it or try printing over USB. Otherwise: please share your project file so that we can reproduce the problem and see whether we fixed it when we fixed it.

I think this is to do with an issue we had which caused some of the gcode not to be sent over the network. Did you print the model by sending over network, or via USB stick? The problem should be fixed in the beta2 release. Could you check whether you still have the problem?

G0 F5000 X162 Y16 Z0.27 That's 1cm from the starting position of the prime! That should never catch the prime poop. I can't imagine that that gcode catches the prime poop.

Lower your bed a little. That should solve the problem.

I think the ridge is caused by the fact that the prime poop and skirt are extruded with a higher speed, which leads to overextrusion when the printer needs to adjust to the new speed. Not sure, though. The blob is normal oozed material like we always see in dual extrusion prints without a prime tower. Perhaps negative retraction prime amount values will make it into the 2.6 release. Depends on what other issues we'd like to solve, though. Spiralize is not really high on our priority list.

Nope. It's not possible in Cura yet. There is a similar setting Outer Wall Wipe Distance, though. Maybe that can help.

Sounds like your bed is to close to your nozzle. Lower the bed a little before you start your next print.

That has been fixed for the 2.5 final release. Thanks for the heads up!

What kind of graphics card do you have? Try updating your driver.

The issue of the poop getting stuck on the nozzle is fixed in Cura 2.5. We'll soon be working on the prime line, but I don't know whether we will make a separate line or just use the skirt line for it.

Cool idea!

Fixed in Cura 2.5

You don't need to upgrade the printer. The Cura software will be upgraded to support those materials.

I do not understand. Please add more words.

Fixed in Cura 2.5

There's no way to manually remove support, but you could try tweaking the Support Expansion Distance. Note that what you think is useless support may actually be usefull after all. Tweaking your support might result in a failed print...

You should post that under https://ultimaker.com/en/community/general/ultimakercom-feedback At least I'm seeing your post...
