  1. I have the same issue on a UM3E. The printer is running for nearly 8 days without any significant stops, just time to unload the print and restart a new one. The fan is correctly installed, no sign of loose connection (no ER17 or ER18). The next electric appliance is an UM S5 0,6 m away and had been there for a year.
  2. Hi I have an issue performing the auto bed leveling : - the slot 2 nozzle height measurement procedure starts, but complete before the nozzle touches the glass plate : there is a gap of 3 mm approx - then the slot 1 nozzle height measurement procedure starts, but complete before the nozzle touches the glass plate : there is a gap of 3 mm approx Done the auto bed leveling 3 or 4 times in a row, without completing the bed leveling procedure Sometimes one nozzles touches the glass plate, but not the other. Sometime the nozzles height measurement proc
  3. I have the exact same problem on two UM3E that are 2 and 1.5 years old, running firmware 5.2.11.20190503 since it has been released. The nozzle in slot 2 is squeezed by nearly two layers, making the extrusion nearly impossible, jamming the core and grinding material. I also have an S5, but without any issues. All printers are printing with 3d Solex Hardcores since the beginning. I print approx 20 hours per day on my printers, and haven't noticed the problem since last Thursday, when I upgraded to Cura 4.4. I print a lot with a different support mat
  4. Hi Everything is in the title. See screenshot. Note that the material was not activated. Restarting Cura does not allow to remove the material either. Another bug out of too many on 4.3 and 4.4 release ....
  5. Hi I have the same problem with my S5, as a Cura Connect group host, that keeps disconnecting from Cura 4.3 and 4.4, but all my printers are connected on a gigabyte ethernet network. Disconnection is mainly while Cura performs processor intensive tasks (saving a project, slicing, changing material, changing profile) but also occurs while Cura is idle. Some weird informations on Cura 4.4, printer is said to be connected on the top left, but going to the printers tab, it is not marked as connected. Still it is possible to send the print to the printer by netwo
  6. Yes I did rotate the model 90° along the Z Axis in order to fit on the build plate. I haven't noticed the bug before, as it's pretty rare to have to rescale not uniformly a model before printing
  7. Hi I have a model to scale, but not the same ratio between X / Z and Y. X and Z should be scaled 99,6 % and Y 98,8 %. So I have first rescale uniformly the model to 99,6 %. Then unchecked the uniform scaling Then changed the Y ratio to 98,8 but not clicking Then after clicking, the result is Looks like the X and Y are not properly taken into account. I've redone the following test, starting from a full scale model, unchecking the uniform scaling Then setting the X to 90 % and
  8. Nallath Issue has been created in GitHub with the same name. Thanks for your support
  9. Hi Nallath Here's the logs. I will try to update GitHub this evening Best cura.log
  10. Me too. Annoying.... Would like to have the capability back ASAP. The only thing that keeps me with the 4.3 is the option to place a face on the bed. I'm about to downgrade to 4.2 given the bug on the connected printer that keeps changing and the fact that the app is slower on Mac than previous version.
  11. Dear community I have issues with Cura 4.3 on MacOS Mojave (don't know if the os matters) since I've upgraded from 4.2.x My network configuration (LAN only) is a UMS5 as a group host and 2 UM3E part of the group. The connected printer in Cura is the UMS5 of course. It has worked perfectly, changing printer using the Printer tab. But since Cura 4.3, quite often, changing from UMS5 to UM3E in the printer tab changes also the networked printer and creates an error as being connected to a non Cura Connect Group Host. Also it has created a bu
  12. Hi Link Thanks for the feedback. Yes it's the same issue, but it is consistent, based on the printer configured in Cura. It would be great to have it fixed by Ultimaker team, in order to get consistent results across the different printers. "Not in skin" might be a good option, with a slightly longer print time, but not as much as with no combing and without the hassles of the retractions.
  13. Hi Link Thanks for the feedback I used the wording "solid infill" as in Simplify 3D, but it is bottom and top layers in Cura wording. I'm printing with a 60% infill in the current case. I do confirm that I have the exact same parameters in the both profiles and Cura 4,2,1 behaves differently. So it is a bug. I checked every single parameter which is not hardware related. On the UM3 it combs within the infill, with no retraction On the S5, it is like setting the combing parameter to "Off" or so. I have attached the files
  14. Hi to all I am printing the same parts on both S5 and UM3E using Cura 4.2.1. I have noticed when printing on the S5 that it performs retraction when printing the infill of the solid infill layers. I have set the Combing Mode to "Within infill" on both profiles and have the same parameter (not printer related) on both profiles. On the UM3 Cura has sliced the solid infill without any retractions between lines of the infill, but on the S5 there is a retraction between each line. See screenshot The slicing has been done on the same installation of Cura
  15. Hi Smithy Thanks for the feedback. Indeed the black sliding blocks are very reliable on the UM3, no problem at all after 2 years of intensive usage on my first UM3. I cannot say the same on the S5, at least for the ones handling the Y Axis. For my understanding, the sliding blocks were white at the beginning (heritage from the UM2) then black. Are you confirming that the new S5 are now shipped with white Matt blocks ? Should I request those to my provider ? Best David
  16. Hi I don't think the old version is white and the new black because the blocks are exactly the same on the UM3 and they are black on my UM3 bought well before the S5 was announced. There is some oil on the axis end over the time, but currently it doesn't create any problem on the rear sliding block. I've made a check after replacing the blocks yesterday and the faulty one is clearly worn by some 1/10 of a millimeter. I believe there is some design flaw on the sliding blocks (at least the black one I've got) and the brackets are not big enough to ensure
  17. Hi Job Thanks for the information. My printer was with the black blocks when brand new. So in June when the French distributor sent me black blocks in order to repair, that seems to be normal. In between, I've bought some spare ones in order to minimize the downtime, it's the same on the UM3. They are black too. I will ask for the new version for the replacement parts. Best regards
  18. Up .... With some videos it might be more clearer. https://www.dropbox.com/sh/bcmea9jyjpd5sm2/AAC20bI6zPjhoiX2-iZW57mha?dl=0 The issue is the small clips on the sliding block are wearing and the fit is not snug anymore with the rod. The issue appears only on the Y axis, which is handled by the sliding blocks. The X Axis is supported by the sliding blocks, so no issues. Thanks for your feedback
  19. Hi I had an issue mid June were the Y axis of the print head was no more held by the sliding blocks and dropped down after 6 months of usage of the printer. I replaced them under warranty, thanks to the French Ultimaker distributor. Today I discovered that one of the sliding block that have been replaced is now not snug any more and the Y axis is going to get out of it, after only 2 months of usage. As it becomes recurrent, it is very annoying and let me think about a design flaw. For a 6 k€ professional grade printer it is a bit of a problem having it
  20. Here's the repaired file of the Printcore Lever. It is optimized for a low shrinkage material, certainly would need testing and tweaking for materials like Polycarb or ABS. UM3CoreClip_PL repaired.stl
  21. I have successfully fixed my print core using the model from Thingiverse in my previous post. The model has to be fixed with Meshmixer (Make Solid feature). I have printed it with ColorFabb HT Clear. But in order to get the dimensional accuracy, I haven't tried to get a clear print (increased material flow and high temps would have increased the dimensions) It should handle without any problem the high temperatures in the enclosed printer. The only point is the stiffness of the HT. It would have been better to print it with transparent PC, with
  22. Hi Smithy Thanks for the feedback. Indeed it's on Thingiverse. I'm just back from my annual leave and didn't had the idea to thingiverse for the model. I will have a try with that one https://www.thingiverse.com/thing:3003778 As I print often with a fully enclosed printer material like ABS, ABS/PC, CPE+ or PC, I'll go for a CPE + print. I let you know
