Ultimaker S5 disconnects from Cura Connect frequently
V3DPrinting replied to thelemurking's topic in Ultimaker 3D printers
I am still using Cura 4.2.1 because I had no disconnections over ethernet on my S5. Also I haven't upgraded the FW, still 5.2.11. But I was thinking of an upgrade. In my case disconnections were linked to the creation of a bunch of "shadow" printers by Cura 4.3, 4.4 and 4.5 (all were a PITA regarding this weird behavior). Printer were visible in the printer management tool, but not connected except one. That was messing up the connection. Is that your case? I had some calls with Ultimaker Team, but they were saying not to be able to reproduce the problem.... -
My BCN3D Epsilon has arrived and will be production ready today. Having some free capacity on one of my UM3E, I have downgraded to 4.3.3. So far, for the first dual extrusion print, my 2 printcores (both 3d Solex Hardcores) are leveled at the same height. So the problem was FW 5.2.11 on UM3E I will downgrade my other 4.3.3 too over the weekend. And not going to upgrade anymore. Again poor non regression tests from the Ultimaker FW team. Thumbs down !

Ultimaker S5 disconnects from Cura Connect frequently
V3DPrinting replied to thelemurking's topic in Ultimaker 3D printers
Also having all my Ultimaker printers wired and the S5 host with 2 UM3E slaves. With Cura 4,3 and above, the S5 disconnects frequently from Cura. This may lead to many instances of the networked printer created in the Printers list. Since I've downgraded to Cura 4.2.1 not any single disconnection from Cura. Regarding the disconnection from the web page, I haven't noticed it under macOS 10.14 and Safari, even with Little Snitch -
Cura 4.4 Multiple serious issues with projects
V3DPrinting replied to V3DPrinting's topic in Ultimaker Cura
Hi @maht Sure we should have a video call. I am pretty busy with COVID products, but we can manage to make 30 min video call this afternoon after 15.00. Send me a PM with the link. -
Cura 4.4 Multiple serious issues with projects
V3DPrinting replied to V3DPrinting's topic in Ultimaker Cura
@ghostkeeper I am not sure, still have the issue with 4.6.1 see my post on GitHub I do not agree at all ! It was perfectly working without ANY disconnection on 4.2.1 see my post from January. In addition, my hardware (printers, firmware, network) is exactly the same with 5.2.11 FW, LAN connection, same Ultimaker cluster. And it's not a WIFI issue as all my printers are wired. The problem is there since 4.3 release. I have just downgraded to Cura 4.2.1 end of the morning, since no more disconnections. Also the networke -
Cura 4.4 Multiple serious issues with projects
V3DPrinting replied to V3DPrinting's topic in Ultimaker Cura
@ghostkeeper I have upgraded to 4.6.1, but the same bugs are still there : - material are not loaded properly opening a project (GitHub issue #6626) - some materials cannot be removed (GitHub issue #6731) - disconnections - messing up with the networked printer 4.5 and later have optimized tool path compared to 4.2.1, which is stable, that's why I'm not downgrading a second time. So please fix the bugs ! -
Cura 4.4 Multiple serious issues with projects
V3DPrinting replied to V3DPrinting's topic in Ultimaker Cura
@ghostkeeper` Any update on these issues. On top of them I also have multiple disconnections with Cura 4.5 and strange behavior regarding the networked printer management. It might be linked with this issue, due to shadow printers not properly purged when uploading a project. See the screenshots. I don't have any logs nor time to explain more. Just have a look at the screenshots. After a disconnection I had this message Trying to reconnect I had the following Weird isn't it ? Another bloody bug in Cura 4.5 ! -
Cura 4.4 Multiple serious issues with projects
V3DPrinting replied to V3DPrinting's topic in Ultimaker Cura
I do confirm that this wrong behavior / Bug is present on 4.5 and happens when loading a project based on a different printer than the previous one. -
Cura 4.4 Multiple serious issues with projects
V3DPrinting replied to V3DPrinting's topic in Ultimaker Cura
No at all, I've created the materials when reinstalling from scratch the 4.2.1 months ago. I know about the fact that the settings are specific to each printer type (and also printcore). The bug is within the same printer type. I create a project using my custom material with 6,5 mm retraction distance on my S5 then save it. Reloading the project, overwriting the printer, material and profile definition, the material is often altered and the retraction set to 4.2 mm (which is not standard nor custom for me). -
Cura 4.4 Multiple serious issues with projects
V3DPrinting replied to V3DPrinting's topic in Ultimaker Cura
@ghostkeeper Thanks for the head up. I'm 100% sure, I am editing my custom material : Colorfabb PLA White Quite often, even after carefully saving a project with my own retraction distance (8mm), standby temp (100°C), retraction speed (25), when reloading the project in the day, retraction is set to 4.2 mm, 35 mm/s and standby temp is at 175°C. Exactly the same issues as the bug I've found on 4.4 and 4.4.1. Same bug regarding the disconnections and shadow printer creation. That's my printers connections after half a day working. -
Cura 4.4 Multiple serious issues with projects
V3DPrinting replied to V3DPrinting's topic in Ultimaker Cura
Also numerous networked printer disconnections. Basically the PITA as the 4.4 and 4.4.1. Please Ultimaker Team fix the bugs ! -
Cura 4.4 Multiple serious issues with projects
V3DPrinting replied to V3DPrinting's topic in Ultimaker Cura
@nallath I have finally migrated to 4.5, from my previous 4.2.1 installation The issues are still there, but impact seems to be less. - a new networked printer is created each time I switch from S5 to UM3E. - material settings are altered from the saved project (i.e. retraction setting) After removing all the networked printers, reconnecting my S5, quitting Cura, reopening Cura and loading my project, another instance of my networked printer has been created, not connected. Removing the non active networked printer removes all c -
Dear community I have an issue with my S5 machine definition in Cura 4.2.1 after cancelling a project during the loading procedure. Cura is set up with an S5 as the Cura Connect host (networked printer) with 2 UM3E part of the group. Cura was configured with the S5 as the current printer. I have opened a project based on an UM3E for the printer, but at the second pop up, cancelled the project opening. This has altered my S5 printer definition in the printer settings : - Extruder 2 nozzle offset was set to 18 mm

3d Solex Hardcore jamming when ironing
V3DPrinting replied to V3DPrinting's topic in Ultimaker 3D printers
Very accurate analysis of the problem. In fact it seems at the first look to be an heat creep. But after replacing the printcore cooling fan and printing successfully the same part without ironing, even with multiple parts, it is more an excessive pressure in the print core, having the filament softened too much. It is easy with PLA to soften it @55°C or just above. I have changed the PTFE lining of the Hardcore and ensured that the filament path is cleaned, it hasn't change much the issue or the symptoms. BTW I have Bondtech QR3.0 extruders on my two UM3 -
3d Solex Hardcore jamming when ironing
V3DPrinting replied to V3DPrinting's topic in Ultimaker 3D printers
I've been too quick ... Printing multiple parts has reproduced the problem, even with a brand new cooling fan. Again heat creep and the print core jammed with a 3d Solex Hardcore + 0,8 mm nozzle. -
3d Solex Hardcore jamming when ironing
V3DPrinting replied to V3DPrinting's topic in Ultimaker 3D printers
I have done some more testing, with a 0,8 mm nozzle on the same Hardcore, expecting the heat creep would be less severe due to higher flow. No success. Then I reverted back to the UM print core and realized that not only the ironing was creating heat creep due to the very low flow, but also the standard printing. I found out that the print core cooling fan was not running at the right speed, not cooling enough. The issue is a accumulation of strings around the axis of the fan motor, creating some friction and slowing down the fan. I have replaced -
Dear community I have an issue when performing an ironing on a flat surface, highest layer only, with PLA. The hardcore is jammed due to heat creep. I use ironing feature from time to time, but it's the first time I have heat creep. I made larger prints on an S5 with a 0.8 mm Hardcore, ironing nearly the build plate surface was without any problem. I made lots of prints on UM3E with UM AA 0.4 print core without any problem when ironing. But these prints with a 0.6 mm Hardcore are jamming, on both UM3E when ironing. I have ch

Sorry for the late reply after tests done with @gr5. The outcome was that the 3d Solex Hardcores were within the specs and pretty much like the UM print cores regarding the springs. As the issue appears also with manual leveling, we have agreed that the right nozzle should be offset during the calibration process in order to compensate for the difference when printing the first layer. Also we agreed to revert back to FW 4.33 and check if the difference between the two nozzle's heights is still there. Unfortunately, I was off last week and now my printe

The S5 setup is pretty clever as it accounts for thermal expansion (not 100%, but way much than other brands), but it is sensitive to electrostatic charge, as it uses it to measure. It would have been the same with a standard capacitive sensor used as a probe.` You should have your mains ground checked by a professional.

I have redone the same print jobs with 2 Ultimaker Printcores, but with active leveling set to 'always'. The print went well for the two first layers First layer height on material 1 is between 0.25 and 0.28 mm for a 0,27 mm target. First layer height on material 2 is 0.23 mm Which is fine. I have also redone the same print job with 2 3d Solex Hardcores (0,6 mm nozzle for material 1), also with active leveling set to 'always' First layer height on material 1 is between 0.25 and 0.28 mm for a 0,27 mm target. First layer height on material 2 is only 0.09
