I have the 3dSolex Hardcore with 0.4mm and 0.8mm nozzles. When printing I have noticed with both sizes that when the UM3 does the final retract at the end of a print after the nozzle has cooled a little bit that the filament is stuck in the nozzle and causing some grinding and raises the nozzle enough that active leveling doesn't work for the next print. Is there a way to change at which temp the UM3 does the final retract. I have the machine set to PLA and this has happened with two different types of PLA. I had not noticed any issues like this when using the UM printcores.

I view the UM3 camera over the internet using /?action=stream. Everything worked great however I upgraded to the publix beta for iOS11 and now the video flickers. It works fine when I am viewing it locally through the Ultimaker app. Is anyone else running the beta and seeing the same issue?

This is what I did for my printer and it has kept the same address for months.

Is there a release notes page for the new firmware?

I would reach out to your reseller as they should have better troubleshooting or if it is a defect with the printer would be able to offer service/replacement.

What if you do a manual leveling to get the build plate closer to the nozzle and then attempt an automatic leveling?

Does the Ultimaker 3 app connect to view the camera feed on port 8080/?action=stream or does it have a different way to pull the video feed. It appears to be a much crisper camera feed.

Would having a z-offset in the slicer help with this issue if a firmware update takes too long to get out? I know in Simplify3D there is an option to add a Z-offset and I usually have mine set to add 0.05mm to the initial Z height.

No I haven't had any issues. I was just wondering for the 3 if there was any great advantage to a set of $400 extruder motors.

Has anyone tried these out on the UM3? http://shop.bondtech.se/ec/upgrade-kits/ultimaker/ultimaker3-extruder-upgrade-kit.html. I wasn't sure if there was much of a benefit for a $400 upgrade.

While I don't have an answer for you, I would reach out to fbrc8 in the US. They offer support for the UM3 and are very quick to reply. There is also a facebook group https://www.facebook.com/groups/Ultimaker3 where Erin from fbrc8 is quick to help out as well.

The horizontal line is only with Cura. It is where there is a solid layer due to using the gradual infill. I don't see that on the print using Simplify3D. I do however get the vertical blobs on both slicers.

Yeah this was the one I was looking at. https://thegr5store.com/store/index.php/um3upg/ultimaker-3-core-hardcore-with-two-nozzles-pilot-read-full-description-please.html

I am printing a business card holder and running in to issues with marks on the print. I have tried Cura and Simplify3D, but both result in a large z-seam on the print. I would like to use Cura, but I have had a hard time getting a good print with it. Any steps in the right direction would be appreciated. The photo below was printed with the default PLA settings in CURA 3.6

Has anyone used the new HardCores with the 3dSolex branded core? It a little cheaper than the ones based on the ultimaker core, but I wasn't sure about quality.
