I think so, long time ago 😉 Changed the draft to normal, I can import the file now (see new attachment) but when I switch to eSun PETG: the profile is not visible anymore. How can I fix that ? INMOOV Esun Petg Fine 40% infill.curaprofile

PS: try to import this profile, can't import it.. INMOOV Esun Petg Fine 40% infill.curaprofile

just a warning, “dichloromethane” is carcinogenic !! I think Geert is working at a Chemical Laboratory like me, but to you all: don’t use it!

1) Profile import/export system doesn't work very good and needs improvements... For example: I have a exported a nice profile for my UM3, fine quality, PETG: 'inmoov.curaprofile'. When I do a fresh installation of Cura (all old cura-data erased), install my UM3 again and try to import the cura-profile backup, the program complains that it's not possible to import. I have checked the stored profile (it's a zipfile, renamed the extension to .zip): then I see 3 files. Seems to be those profile files are only contains the changed settings based of the used base profile. In my case I used the base profile 'fine'. And this is the case where it goes wrong, in a new Cura configuration you start with a few basic profiles: as soon you store a profile as a new one, all default profiles are gone.. When I start with a fresh Cura installation, add my printer and add eSun PETG, I see only a base profile 'draft'. If you search for Ultimaker profile issues on the internet, you will find enough hits... Personally I would be very happy if it was possible to export/import a profile which is COMPLETE (all settings, not only the diff settings based on a used base profile). Also it would be great if was possible to import a profile from for example a UM3 to the configuration of another type of printer. 2) Profile settings vs 2 extruders Something else: if you use 2 extruders like with the UM3: you can store a profile, but for example the skirt extruder is always extruder 1 or 2? That's not allways what you want, example: you have PETG Blue in extruder1 and PETG YELLOW in extruder2 and you have a nice profile for both extruders (same settings for both extruders). Now you want to use only extruder 1 to print something, with the current software you must check your profile first and change the selected extruder for the skirt, support, etc first to extruder1. Otherwise your print will be made by both extruders. Same thing if you only want to use extruder2. I really like Cura, but the profile import/export system needs a lot of improvement. There are a few plugins now to help you with your printersettings: this is a sign for Ultimaker that this profile/printer settings software really needs more attention and must be improved.. 😉 Arthur

Cura is nice but when you want to upgrade to a new version, it's allways a problem to have your own profiles up and running. I have exported my profiles from a previous Cura version, when I want to import them it's often not possible. As found somewhere on this forum, this is a way to solve it: 1. Set material type to generic PLA and the nozzle size to 0.6mm. With these settings were my profiles shown. If you can't see yours try all the nozzle sizes and even then might my work around still work. 2. To have all my profiles shown with 0.4mm nozzle the following steps are required. In the folder of your profiles (i would strongly recomend making a copy of all profiles at that point in cases something goes south) rename the profiles from .curaprofile to .zip. 3. unzip the two files in the new zip document. edit both via editor and change "quality_type = draft" "setting_version = 6" to "quality_type = standard" "setting_version = 15" (check the newest version for the version numbber) or "quality_type = super" "setting_version = 15" (for super fine printsettings) 4. zip them together again and change the .zip back to .curaprofile 5. import But that doesn't work allways, on the moment I got this error: "Failed to import profile from D:/CURA/profiles/UM3/INMOOV.curaprofile: Quality type 'fine' is not compatible with the current active machine definition 'ultimaker3'." On the moment the best way is to see all settings of the specific profile with the "Profile Analyser" plugin, print it and make a new profile with the data.. Would be great if this profile import/export tool could be improved a lot, it's still not working very good....

Thanks for all your comments 😀 After calibration of the x,y,z and e-steps i get now the accurate sizes 😀 I found out that the z-steps are ok, but the others needs to be calibrated for every new rol of filament!! The steps can be changed in the firmware (.sjon file). New problem: after I got a firmware update, this option is not available anymore, or maybe the setting file is moved to another place. (I will look for a fix this weekend) Anyway: I have created a calibration part and a howto on: www.thingiverse.com/askmurphy If you like, print the test object and check your step-calibration (you can use the calibration spreadsheet on the above page) and show your results here. The Ultimaker3 is a nice printer but for accurate prints it’s not good at all if you don’t calibrate the printer. The 2.85mm filament is one of the main reasons, the print accurate error is much higher then with a 1.75mm filament.. If you ask Ultimaker about this: you get default answers, useless. If you are interested, i can place another calibration part here, narrow fit parts..

I have an Ultimaker3, it prints nice but when I print some parts which must be combined later (narrow fit!) then these parts didn't fit at all. Parts are allways too big. Print PETG with 40mm/s, 245'C nozzle, 80'C bed. Bedleveling calibrated. Also tried calibrating the steps (X,Y, Z and extruder). Used all kind of filament, Ultimaker brand or whatever: same results.. As long you print something which doesn't need to be printed very accurate then the printer is ok. Is there somebody who have this same problem and nows how to fix it ?

If you need some handy tool for the X,Y,Z and E-stepper calibration, check this: https://www.thingiverse.com/thing:3706923 ;-) Arthur

I have exact the same issues with my ultimaker3. I think the answers of the ultimaker people are not right too. Really strange that the Ultimaker company does not have more focus and knowledge about x, y and z calibration... The horizontal tuning works indeed, but equal for x and y: that's silly... x, y and z callibration is important to make accurate prints like Inmoov parts. I have tested the z-stepping first: moving 100mm by command gives 107mm.. i have changed the z-steps, now it's doing exact the requested 100mm. The printed Inmoov parts has now a better fitting, but it could be a bit better. An 3D-printer must do exactly what the gcode wants, x, y and z tuning must be accurate. Will tune the x and y tomorrow, will let you know how it works..

Thanks for the bonus info, great !

My ultimaker3 had a default factory extruder step setup of 369 steps/mm. When I tested with 100mm cold extrustion, I got 105.9mm.. y * 105.9 = 36900 y = 36900 / 105.9 = 348.4 (round to 1 decimal) =========================================== SSH root access to your Ultimaker, login after that with: ultimaker/ultimaker. => 100mm extrusie: sendgcode T0 sendgcode M302 S0 sendgcode G92 E0 sendgcode G0 E100 => Test your new step value first with: sendgcode T0 sendgcode M302 S0 sendgcode G92 E0 sendgcode M92 E348.4 sendgcode G0 E100 By the way, it's better to extrude 200mm or 300mm: smaller error ;-) => If new value is ok, make it permanent: Changed 9066.json (= Ultimaker 3 ) file: { "inherit": "um3.json", "properties": { "machine_type_name": "Ultimaker 3", "default_steps_per_mm": {"x": 80.0, "y": 80.0, "z": 400.0, "e": 348.4} } } REBOOT printer, login again and check the file: value still ok ? (sometimes it is not stored). Do a new test print (200mm extrusion) and look if the length is still 200mm ;-) The above calibration is not inside the FAQ of the Ultimaker website, I think it's a must ;-)

I had the same issue: used the Z-as plugin for finetuning bedleveling, worked great ! But after this new firmware upgrade, the printer is printing in the AIR (about 3cm too high!!). Now disabled the plugin, it prints now on the glass again 😉 BUT: it's a BUG, I hope they will fix it asap !!
