It does not run on my MacBook Retina with MacOS High Sierra 10.13.3 When I try to start it, I can see the splash screen until "...loadind scenes", then it opens some confirmation page and immediately exits without trace. Can I help with some logfiles? Where to find? Cheers from GY, -pl

Same annoying graphics problem for me: MacOS and Cura 3.2 as well as Cura 3.2.1 The problem did show up in an earlier (pre 3.1) version of Cura, but does not happen with Cura 3.1.

I would suppose that it works only on nonstructured, vertical walls, doesn‘t it?

This would be very helpful. As you guys suggested, I played around with the settings and as it turned out, the retraction setting was the culprit for the seam. I disabled it and set the layer height to 0.4mm, speed 25mm/sec, inreased the extruder temperature to 210°C and voila! (Compare before/after version in the photo) Thanks for all your kind support!

Yes, besides the seam it looks nice. Going up a bit with the extruder temp seems to help avoiding the faults, as well as reducing the print speed. But how can I get rid of the seam when using the AA0.8 nozzle? Will try to dive into the g-code and compare the .4 and .8 codes. Maybe that could help to understand what's happening here. Btw., I'm using Filamentworld PLA clear (PLA300XCLR). It comes on a bigger spool, which makes it impossible to put another spool on the UM3 spool holder. And yes, I printed and tried the alternative spool holder, but am not satisfied with the construction. So I changed back to the UM3 genuine holder.

Thanks for your responses and recommendations! Seems the problem with the faults in the walls goes away with reduced print speed, so this should not be a problem any more. I have attached a photo with different samples, the evolution goes from left to the right side. Parts 1, 2 and 7 (from left to right) were printed with the AA0.8 nozzle and all of them have a seam. I tried this with 0.8, 0.4 and 0.2mm layer size, no change. During printing you can see that the print stops shortly at every complete layer. This is independent from the retraction setting (on or off). The objects 3, 4, 5 adn 6 (from left to right) were printed with the AA0.4 nozzle. After reducing the print speed they all came out perfectly, without any seam. The printing was one continuous spiral. Layer size 0.2. So basically one question remains: is it possible to use the spiralized mode, without a seam, with the 0.8mm nozzle and what are the required settings? Thanks for listening ;-)

I'm trying to learn how to use the the spiralized mode. Not satisfied yet, because I expected that there would be no seam, but there is one, see image. What am I doing wrong? And what is causing the other faults in the surface? Material used: PLA Temperature: 220°C AA 0.8mm print core Cura 3.1 and 3.2.1.

Have a look at my former post, maybe it helps: https://community.ultimaker.com/topic/19274-error-i2c_head_comm_error-how-to-deal-with/?do=findComment&comment=187544

I don't know what specific problem you have, but your behavior does not fit into this forum, so PLEASE. GO. AWAY. Thank you.

The nasty scrambled-font-problem is there again with Cura 3.2 on my MacOS 10.13.3 version.

After some more problems, today I changed the cable. Thanks to your helpful hints regarding the cable cover, it went without problems. Hopefully the nasty ER18 will have gone. Thanks again!

No idea yet how it sounds, because the guy who received the horns from me hasn't yet finished the speaker construction. I constructed and built it (the two horns) on demand.

This is a Tractrix horn that I constructed with Fusion 360 (imported calculated data) and printed with Cura on my UM3. At the back side of the horn a tweeter is going to be mounted and the whole stuff will become part of a stereo audio system (I made two of them for a friend of mine who is an audio fanatic). Material: Ice PLA, colour "Glamorous Gold", printed with 0.8 nozzle and some PVA support.

It seems that I do need to replace the (UM3) print head cable, as the 18 error raised its ugly head again a couple of times (interestingly right after aborting a print job, like Kortben described above). I already bought a replacement cable at my own cost, but am not sure how to replace it, because I didn't find out how to open/remove the right hand side stepper motor cover sheet which also hides the print head cable leading down to the electronics pcb. Any hints?

You made my day! This setting was activated on my MacBook for the Thunderbold Ethernet interface. After disabling it, Cura no longer crashes. Thanks for pointing this out!

Are you using the Apple Thunderbolt Ethernet interface?

I am looking for a recommendation for the ultimate gold PLA. The PLA from ICE filaments that I tried (Glamorous Gold) could not convince me. Thanks :-)

You beat me to it Yes, because of problems with extruder 1 I printed the model with extruder 2. As you saw, I changed the setting for extruder 1 instead of extruder 2. Wasn't aware that the infill can be set separately, stupid me. Thanks for pointing that out!

When I try to change the infill density of extruder 2 it doesn't change, see layer view in screenshot. For extruder 1 this works just fine. Am I doing something wrong or is this a special feature of Cura 3.0 (seen already with Cura 2.7)?

The problems have been with two different Print Cores (0.4 and 0.8 ), but always in the same slot (#1, left side as seen from the front). I always double-checked the proper seating of the Print Cores ("click" after insert) and also checked the cable connection on the print head side, which didn't show any obvious problem. Regarding the logfiles, I would like to send them to you via wetransfer, but need an email-address, could you please send it to me? BTW, to be able to quickly collect the logs I have written a small shell script to run (on MacOS) after a problem occured; maybe it could be helpful for some other person: #!/bin/bash## get_um3_status.sh## Collect relevant information from UM3 for troubleshooting purposes## 28-Aug-2017 First edition -pl (peter.lelie@lelie.de)## define target IP addressUM3=192.168.yyy.xxx#DATADIR=$(date +%Y_%m_%d_%H_%M_%S)echo $DATADIRmkdir $DATADIRcd $DATADIR#curl --output log.txt http://$UM3/api/v1/system/log?lines=1000curl --output system.txt http://$UM3/api/v1/systemcurl --output head.txt http://$UM3/api/v1/printer/heads/0curl --output tempflow.csv http://$UM3/api/v1/printer/diagnostics/temperature_flow/10?csv=1#cd ..#

Would it make sense to check the other side of the extruder cable (@ the controller board)?

Sad to say that the problem has happened again, twice in the last two days. Would it be helpful to post logfiles? Contacting my reseller appears not be helpful; they want me to send back the device, which I want to avoid because I do not trust the DHL people to be careful with my UM3.

The characters are no longer garbled in 3.0.1-Beta, looking good, thanks!
