Hi, thanks valcrow. And what about first layer height? Can I keep it same as for 0.4 mm nozzle?

Dear all, I have my Olsson block mounted now (yeahhh). Now I want to do a test print with 0.8 mm nozzle which came with the Olsson block. In the past I printed only with the original heater block and the original 0.4 mm nozzle from Ultimaker. My questions: 1. What settings I have to change in Cura to print with the 0.8 mm nozzle? 2. Is there anything else to consider printing with 0.8 mm compared to 0.4 mm? Thanks a lot!

Hi, I ordered the famous Olsson block from www.3Dsolex.com. Some nozzles came with it, which look like this: . On 3Dsolex online shop they also offer nozzles like this: (image from www.3Dsolex.com) Here my questions: 1. What is the difference in both? 2. Is there any benefit of one compared to the other? 3. In general what nozzles do fit into the Olsson block? What is to consider - the thread size? Thanks!

Dear all, today finally I got some time and wanted to install my Olsson block. Unfortunately I could not remove the temperature sensor, it broke, so I have to order a new one. Anyway, since I unmounted the original heater block I took this opportunity and examined the PTFE-coupler. Inside at the bottom end I can see a groove. See left part of the attached image: The groove is not everywhere. It is distributed on I guess 60% of the inner diameter. 40% are flat without any groove. See right part of the attached image. My questions now: 1. What is the reason for this groove? 2. Should I replace the coupler? 3. If I don't replace the coupler, what consequences it has e.g. for printing, print result? Thanks for any help!

Hi, nicolinux asked me as well if I want to get a ferrit core (@Nicolinox: thanks). I answered him that I want to be sure if I face exactly the same problem and therefore I did a testprint (Innofil PLA Yellow) with the 20mm cube at 215°. Here are the results: Last bottom layer 1: Last bottom layer 2: Top layer: (Forget the blob on the image 'top layer', it happened because I did a long pause to take the bottom images. A big string of filament was coming out of the paused nozzle and I forgot to swipe it away on resuming the print) As you can see the result is not the best. Then I tweaked the settings (on the UM2 LCD panel) to: - Temperature: 220° - Flow 110% - Speed 90% and got: last bottom layer: Top layer: With these setting I think the result is almost perfect. What do you think?

Hi nallath, OK thanks. I assume someone from ultimaker development team will take care?

I don't want to push, but can anybody tell me if 'no infill' on Concentric pattern is a bug or not? Thanks ;-)

Hi, thanks for the link, I downloaded the latest version now and tried again. The problem is solved now. And bagel-orb was right. For some reason the infill pattern was set to grid instead of lines. I don't know why since I never had this option visible in my Cura versions. Anyway I made this option visible now and detected it was set to grid. Then I switched it back to lines and then the infill was same as in legacy Cura again, see here: Just for fun I set it also to Concentric, but there is no infill at all, as you can see here: Is this also a bug or not?

Hi, where I can download the latest Cura built to verify that this issue is solved?

OK, thanks for this information!

Hi nallath, what does this mean now? - Will the keyboard issue be solved in one of the next releases? - What about the different infill density (at same setting of 50%) of 15.09.81 compared to 15.02.1?

Hi, today I downloaded Cura 15.09.81 beta and did a test on this issue. It seems that the problem is solved - however I face two issues: 1. I set 50% infill density. But the infill density from Cura 15.02.1 is more dense compared to 15.09.81 beta (please compare to the picture in my first post in this thread) (I played a littlebit. If I set infill to 80% on 15.09.81 then it seems to be same as 50% in 15.02.1). So for some reason 50% on both version do not give same infill. - Why is this? 2. If layer view is turned on and I use up/down arrow on keybord to move through the layers then the layer is changed as expected but the 3D view rotates at same time!?! BTW I am on Windows 7 professional 64Bit

Hi nallath, great! Thanks!

Hi nallath, thanks for reply, but I need some more help: 1. Does it mean it will be overidden for forever? Or just for the current print process? 2. During the print process do I still have acces to UM2 settings and adjust the temperature? 3. Is it safe to print now or not? Thanks again...

Hi, normally I do my designs using Autodesk Fusion 360, then I export STL file and go ahead in Cura. Fusion 360 now allows to transfer the designed object to Autodesk Print Studio. Print Studio allows to position the object on the built plate, rotation, scaling etc. similar to what Cura does. A support tool and single layer preview is also included. It comes with many presets for a lot of 3D printers. Ulimaker 2 is also available. Since this is quite interesting I wanted to give it a try and created the gcode using Print Studio and saved it on my SD card. The card I inserted into my UM2 and picked up the gcode file for printing. But UM2 shows a message: "This file will override machine settings with setting from the slicer" I cancelled this since I do not know if it damages something on my UM2. So what settings will be overridden here? Can I go ahead printing? Thanks...

Hi IRobertI, sorry I don't know what you mean. Which screw please?

Hi, thanks that's great - can't await the next version of cura...

user 'neotko' answered (thanks): I think it's the oposite. For layer time x = or less then lift head or pause. So if the layer time you set it's 5 tehn all the layers with that or less time used will have a pause or lift of the head. It doesn't set the minimum layer time but it affects layers with that time or less. So you must set 4 seconds if that's what it takes to print it. Anyway for small items it's really good to print more than one even 3 being that small to allow the material to set. Specially if it's pla

Hi, (copied to here, since I posted in the wrong category) Today I wanted to print a tripod / photo screw. I started the first print and saw that the thread is not very clean, looks like two or more layers melt together. I watched the print process and could see that the printer takes only 4 seconds for one layer for the shaft and thread layers. Now I increased the 'Minimal Layer Time' to 15 seconds, as you can see here: Then I did a 2nd print but still the layer time for shaft and thread is only about 4 seconds, not 15 what I set under 'Minimal Layer Time'. I checked several times, and saved the file with 15 sec. 'Minimal Layer Time' using a different filename, but UM2 does not increase the layer time :-( What I am missing? Thanks...

Hello baymaker, since I (still) have the same problem, could you please explain more detailed how to assemble it your way? - What do you call 'the nut'? - What is (exactly) to do to solve the problem? Some drawings/images (if you can provide) would be nice. Thanks!

Hi ghostekeeper, thanks, seems to be my 2nd bug I found ;-)

Hi, in Cura 15.06.02 and 15.06.03 it seems that the 'Defaults' button inside the preferences is not working? If I e.g. enable Preferences-->Machine-->'Wall thickness' I can see that it gets enabled and 'Wall thickness' appears under the quality tab. If I hit 'the 'Defaults' button, nothing happens, 'wall thickness' keeps enabled and visible on the quality tab. Normally I would expect that hitting 'Defaults' will reset all changes back to the default values - but it does not? Here is a screenshot of the 'Defaults' button: What I am missing?

Hi xisle and gr5, thanks. I created a new issue on github now: https://github.com/Ultimaker/CuraEngine/issues/231

Hi gr5, I already have an github account, but where can I add a bug now? Could you provide a link to the ultimaker github bugtracker? Thanks!

Hi gr5, thanks for testing. I found a bug - wow ;-) Good luck for the Ultimaker development team to solve this issue. Thanks! PS: How do we get an informatiopn if this issue is solved?
