  1. I would like to send out a big THANK YOU to all the developers on this version! It is SOOOOO much better to be able to move the model around on the build plate (this was driving me nuts before) and it's amazing how handy the new feature is to put a designated face onto the build plate. When I first heard about that feature it was 'oh, ok', now it's 'holy cow is that ever handy'. I had no idea what I was missing. The issue with saving profiles on a second configured printer also went away - that was a biggy that made me avoid using one of my printers. The only aspect that is still a bit troubling is some of the sluggishness (for example when selecting an alternate printer or searching for a particular setting) but with a bit of patience and maybe some more computing power it isn't too bad. THANK YOU !
  2. I just installed 4.3 beta. I have only done a brief look at this old issue. I am very optimistic that the issues I was having seem to be resolved! THANK YOU !!!
  3. I believe that, other than the issue of selecting things, the remaining things are 'operator problems'. Keeping in mind that I am just a user, as far as I know Cura can't drop one thing onto the surface of another (excepting dropping a model on the build plate of course). IMHO this would be rather useless because how would you deal with anything that doesn't just sit on the surface. The way to do this is to create your model in two sections on the same drawing and export it in two STL files. When Cura combines them, they are combined as they are in the original model relative to the origin as specified in the model. This could be with the arrow key on the surface or embedded or a combination of the two. I hope that makes sense .... I do believe it is possible to combine two independent models into a group (never used that function) but that is rather inaccurate. I think when you talked 'group' you might have meant 'merge' which is what I assumed your post was about.
  4. Without sidebar plugin installed
  5. If you are running Cura 4.2.1 and have multiple printers configured, there seems to be a bug related to saving/updating profiles. I have reported that earlier but have not heard anything more on it. If you update the CR10 profile in any way, chances are that the issue will come back (it does with me)
  6. This may be related to the problem I reported in this thread here:
  7. I just tried to move an average sized object. I tried about 20 times before giving up and printing in the place that Cura decided for it. I have started to use the new feature on the lower left of the Cura main screen that names the prints on the build plate. This always selects the print and is quite handy. Alas, every time I clicked on either the center of the x/y/z arrows or on the arrow heads, the arrows would disappear. Eventually I gave up rather annoyed at the situation.
  8. Well, not exactly ... 😞 I deleted the empty profiles, started Cura and there was no error message about corrupt profiles (yeah) Then I changed an existing profile for the CR10 and exited Cura (crossed fingers) Then I opened up Cura again to find out that no, the profile had not actually updated and now I am seeing some more 'empty' profiles (crap) Then I decided to be stupid and deleted what seemed some odd profiles (custom_extruder_2_%232_pla_on_glass.inst.cfg as well as version 3,4,5,6,7 and 8 of the same) and closed down Cura. Crossed my fingers and started Cura .... oh crap !!!!!! Cura starts up and thinks it's a brand new installation ...... 😞 Update: restored the configuration folder from backup and ..... yeah !!!! we are back to the errors of the corrupt profiles. Deleted the empty profiles, change one data item of a profile, updated the profile and find out that Cura had created another 'empty' profile. Deleted the empty profile, loaded a different profile, changed one data value, updated the profile to incorporate the change and again Cura created an 'empty' profile. So, based on what I am seeing, I would say that Cura, instead of updating the correct profile with the new data, writes an 'empty' profile. So it creates the corrupt 'empty' profile and never actually updates the profile that I tried to update.
  9. Hopefully the compressed 4.2 folder you are asking for is attached .... 4.2.compressed.zip
  10. Ok, let me try and give you a sequence of operations to reproduce the behaviour: Load Cura 4.2.1 on Ubuntu computer .... sorry for the long post that follows: Cura is configured for two different printers with one being a single extruder printer and one being a dual extruder printer I start Cura Cura starts (in this example) with the dual extruder printer active and the 'print settings' dialog open I change the layer height figure, the profile shows a star indicating an unsaved condition, I click on the star, I get the 'preferences' dialog , profiles sub dialog and I select 'update profile with current settings/overrides. The dialog indicates that the settings are saved (by graying out) and I close the 'preferences' dialog. I close Cura I open Cura again and verify that yes, the print settings dialog shows the changed layer height. BTW, Cura reports configuration errors with several profiles named 'creality_cr-10_empty, empty #2, #4 and #5 and asks me if I want to throw out all my configured profiles and printers. I dismiss the warning without resetting anything. I now switch the active printer from the current dual extruder version to a single extruder version.(creality cr10) Cura ponders life over this for a rather lengthy time and then shows the new selected printer. Again, the print settings dialog is open (but not on the custom profile that was last active but on the 'extra fine' canned profile I update the profile to one of my custom profiles, set layer height, update the profile, save the changes and Cura thinks it has saved the changes. I close Cura I open Cura I again get a message of configuration errors but this time the errors are for the creality cr 10 empty #2, #4,#6, #7 and #5 profiles (note that Cura is creating these empty profiles every time the creality printer is selected) The print settings dialog that opens up by default is one of the 'empty' profiles and not the profile that was last used. I select the profile that was last used but the layer height is not what was previously saved (it appears to be the settings of the 'empty' profile) .... and there we are .... hopefully that explains things. No actual models were loaded at any time. Let me know if you you want any log files (and let me know where to find them on a Linux box running Ubuntu) BTW, I didn't want to post this long song and dance if this was a known problem which is why I started with a minimum of information first.
  11. I can confirm that if you configure the materials on the top bar, they seem to propagate. Having said that, the whole system of materials (and to a lessor extent the profiles) is very confusing to me. It is totally non intuitive. Even after spending a couple hours of trying to figure things out, I eventually decided to give up - maybe future versions will improve that aspect of Cura. This mini rant applies to multiple extruder setups - I had no problems with single extruder operation but then I never used the 'material' portion. What I did was to create custom profiles with the material used in the profile name so it was easy to select the right profile based on the material used at the time (for example 'Amazon Basics PLA on glass'. I tried to make sense of the whole 'materials' and 'profile' system but the on-line documentation was no help. I am struggling with the very basic premise of separating materials and profiles. In my thinking a particular material has a particular profile and the two should not be separated like they are currently. I am sure there is a method to the madness the way Cura is designed and it is quite likely that I am using the system in away it never was designed for but I have not found anything that explains the way that this aspect of Cura 'should' be used. If anybody has a URL to a tutorial that explains the basics of how to use materials and profiles, I would appreciate a pointer to it. Little things like a single 'profile' selector box for two separate extruders confuses the hell out of me.
  12. I am running 4.2.1 and have two printers configured. Profiles update fine with one printer but when the other printer is selected, any updates made to the profiles will not be saved (although Cura thinks it has saved the changes). I also get corruption errors and every activation of the non-updateable printer seems to generate a custom profile 'empty'. It is this profile that generates the corrupt configuration errors. Cura does give the option of resetting but it warns that this will remove all profiles and printers and I really don't want to go through setting up everything again.
  13. I have selection problems as well as movement problems. It might take many attempts to click on the model before it gets selected. Once selected, the chances are 50/50 if clicking on the arrows or circles will get the desired action or if it simply ends in a de-selection of the model. Very frustrating ! The issues seem to appear more often than in version 3.x but I can't be sure.
  14. While the 'make overhead printable' was definitively causing issues, I am still not getting the results I am expecting. I think there is a second issue at work. Here is a screen shot of the first layer preview: You can see that the area of the blind ring (refer to the picture in first post) has two loops of 'helpers' which are screwing up the works. I have also included the project file. The 'helper' lines only seem to be printed on the first layer as if they are there to hold the inside post in place. On the assumption that maybe the details were too small to print, I increased the depth and width of the blind channel with the same result. Edit: For some reason I decided to go from 'brim' to 'skirt' mode under adhesion and the helper lines went away. Now when I had 'Brim' mode selected, I had also checked 'brim on outside only'. Does Cura possibly think that feature is a new model as the inside post has no connection to the rest of the model on the first layer? Is there some option that I could enable to print with a brim but not have brims generated for these kind of 'inside' features ? (hope that makes sense) Is this one of those situations where I have to adjust the model design to make it printable (small bridge on the first layer to attach the inside post to the outside)? Another edit: I redesigned the model to have a tiny bridge over the blind channel which fixed the issue of the helpers. I am still wondering if there is something I can do in the Cura configuration or if model redesign is the only option. printing blind channel fail.3mf
  15. I am happy to report that setting 'combing' to 'not in skin' helped .. but the real star was 'pressure advance' which is a function in the controller and not in Cura. I have a very long bowden tube (somewhere around 650 mm) and this caused a considerable delay between the printer starting to print a circle and filament actually coming out of the nozzle. Pressure advance has eliminated this issue and now when Cura tells the printer to put down filament, it actually happens ! I am using a Duet controller and the suggested setting for the average bowden tube setup is a value of 0.2. A direct drive printer needs about 0.05. I am using a value of 0.8 (!!!!) and am producing a MUCH cleaner print then before when I was using a value of 0.2.
  16. Found the wrench that I had stuck into the works: 'Make overhead printable' in the experimental section was enabled.
  17. Thanks, I will give that a try.
  18. project file attached as requested. sucker foot.3mf
  19. I have a small model that Cura is ignoring features of .... I obviously have a setting wrong but I have been messing with it for an hour now and can't figure out why Cura is doing what it's doing .... In the attached picture, you see a small piece of round rod. It has a center hole and then a blind ring around the center hole. The ring is 1 mm wide and 1 mm deep/high. When the model sits flat on the build plate with the blind ring down, Cura ignores the blind feature. If I rotate the blind ring so it is not on the build plate, Cura is happy with it. Gaaaaaaa ....... 😞 😞 😞 I need an emoji of ripping out my non-existing hair ! 0.4 mm nozzle, 0.2 mm line width to visualize the problem better, 0.2 mm layer height
  20. The printer is a CR10-S5 with a Duet controller and chimera clone hot end. The rest of the print sticks very well (on glass). Only the first loop/circle of the hole doesn't stick. If I increase the squish, the rest of the print has too much material extruded making it a mess. Height above the build plate is very accurately controlled with a hight mapped bed. I will play with the height a bit as well as the printing order. Currently it only prints one (inner) circle but if I set for optimized print order it will print the first two circles and that might help. If I could get the printer to not drool filament as much, I would expect the issue would be reduced as well.
  21. I also have a lot of issues with small holes on the first layer. The biggest issue seems to be that there is always a tiny delay before filament is extruded (from drooling filament as the nozzle moves from the outside of the model to the inside position of the hole. Because the very first circle put down by Cura is a single circle, there isn't anything else to support the circle. The drooling also pulls on the still soft circle and in the majority of the cases the filament from the first circle gets pulled all over the place and gets embedded someplace else. Cura comes back later and prints more layers of wall and then everything starts to stick properly. I could add extra flow to the first layer to give the first circles more stick but that usually haunts me on the rest of the first layer. Possible solutions I could see - extra flow in small first layer features separate from the overall first layer flow when there is nothing else printed that the first circle can hang on to. No idea how this could be implemented <shrug> Maybe a special extra slow mode when printing that first circle for the hole. If the holes could be printed from the outside in, that would also help as the inside circle, that is normally printed first, has something to hang on to. Larger circles tend to stay put by themselves. The kinds of holes that give me issues are 3 mm inside diameter with a 0.4 mm nozzle and a 0.5 mm trace width. I tend to print a lot of those for some reason.
  22. Either I am missing something - in which case I would appreciate a pointer to the right place to look, or this is a request for an additional feature. When setting up a dual nozzle print with two different materials, I can only select one profile. It would be nice if I could select Petg for example on print head one and support material on print head two instead of having to change all the settings for printhead two manually to reflect the different parameters of support material. As I said above, if there is a mechanism that allows that, I would appreciate a pointer to that.. A somewhat related question or request for clarification .... I am currently running two printers and slice with a single copy of Cura, selecting the printer to do the slicing for first. I then select a custom profile from the list shown to me by Cura. If I have a profile called "PLA on glass" that shows in the profile list for printer one, is it kept as a separate copy from the profile "PLA on glass" that I made for printer two ? Is Cura smart enough to keep these two profiles separate or is the appropriate method to deal with the situation to name the profiles as "CR10-PLA on glass" and "Duet-PLA on glass"?
  23. Just to close this thread out, I determined that replacing the hot end with a Micro Swiss hotend was not practical as I am using a piezo z sensor and would have to design and print new mounting hardware for it and re-tune everything. I am now doing many many prints and also printing out the settings for those prints. When each print is done it is taped to the sheet with the settings on it. I found that when I was doing this in a more casual manner (without recording settings) I was getting myself more confused rather than figuring out what works. Hopefully, doing the systematic approach will get me to where I want to go. Thanks again !
  24. Thank you ! I found the file under ~/.local/share/cura/4.1/user/custom_extruder_1+%232_user.inst.cfg but it seems that the file is only up-to-date after printing or possibly after doing a preview. It seems to display only a subset of the configuration but sufficient for my purposes so far.
