  1. 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.
  2. 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
  3. @CarloK I have made the same test print of a Benchy with the same materials as before, but with a 0,27 mm first layer height, 2 Ultimaker Printcores Before printing, I have done the following on the same printer as in my previous post - Ultimaker Printcore AA with 0.4 mm nozzle set in slot 1 - Ultimaker Printcore BB with 0.4 mm nozzle set in slot 2 - Made a cold pull in both print cores -> no material left in the nozzle. - Set Build plate Temp to 80°C (working temp for the job) waited it to stabilize - Set the 2 printcores temp to 240°C
  4. If your mains are properly grounded, it should be OK just plugin in your printer. Better check it. Remember it is a capacitive sensor who makes the bed leveling, triggered by the point where there is no more change in the electrical charge, normally when your nozzle is touching the build plate. But if you saturate your sensor, reaching a plateau, before your nozzle actually touches the build plate, it will trigger the sensor.
  5. Looks like you have a static electrical charge on the build plate that saturates the sensor. Did you made the sensor test ? Is the printer properly grounded ?
  6. @CarloK I have made the test print of a Benchy with the same materials as before, but with a 0,27 mm first layer height. Project file attached.UM3E_3DBenchy.3mf Before printing, I have done the following : - 3d Solex Hardcore AA with 0.6 mm nozzle set in slot 1 - 3d Solex Hardcore BB with 0.4 mm nozzle set in slot 2 - Made a cold pull in both print cores -> no material left in the nozzle. - Factory Reset, skipped the steps. - Cura Connect Reset - Lift Switch calibration - Switching Test done -> OK, see video from my previous post
  7. Yes, I skip the whole Welcome setup steps. My printers are connected via Ethernet, so no need to go through that process. Here's the video of the switching test. Works like a charm. https://www.dropbox.com/s/y2yacheprqknsd2/IMG_4842.MOV?dl=0 @CarloK I am currently making a print with the benchy attached previously. The only change will be the first layer height set to 0,27 mm (default). I let you know and provide the logs.
  8. @nallath @territerriterri Has the issue been fixed in Cura 4.4.1 ? Or should I wait for 4.5 ? Thanks
  9. @CarloK Thanks for the link. That was the type of information I was looking for. Both print core are 3d Solex Hardcore. The left one with a 0,6 nozzle, the right one with a 0,4 nozzle FormFutura TitanX on the left core, Formfutura Helios Support on the right core. No, as the layer height was only 0,1 mm, I reduced the first layer height to 0,2mm. See the project file attached with a dummy model for privacy reasons. I had the same issue with prints using the default first layer height. I first made a fact
  10. @tinkergnome That's the first thing checked. Lift switch had been calibrated and checked right after a factory reset prior to a test print. And the problem is on my two UM3E, so it's likely not to be an hardware issue.
  11. So you are lucky. I'm one of those people having and reporting issues on UM3 since the 5.2.11 on the active leveling / leveling issue. My concern is that with this firmware, even not using the auto bed leveling but doing a carefull manual leveling the right nozzle is not properly leveled and is always below the left one, not allowing any extrusion. I have been through the gcode, and there is no problem with it. So it's not linked to Cura. So the issue is in the 5.2.11 firmware on UM3.
  12. @uncle_bob You are lucky. That was my day to day life with my UM3 before upgrading the firmware. Which Firmware version are you running ?
  13. @CarloK Is it possible to downgrade the firmware of the UM3E to the latest 3.xx version ? How and where to find the firmware. This would solve my issue as the printers were running perfectly before the firmware upgrade to 4.X and 5.x. I don't mind having the sensor test, nor an improved bed leveling, as it is not working. I just want to get back a reliable dual extrusion, reason why I've bought 2 Ultimaker 3 couple of years ago.
  14. I have some updates on this issue on my 2 UM3E. I still have the nozzle in slot 2 squeezed by nearly 2 layers. For some reasons, I have reverted to Cura 4.2.1 (too many bugs on 4.3 and 4.4) I have done a factory reset, rechecked the bed height and adjusted it to 14 mm (recommended height by Ultimaker to perform Autobed leveling), increased the spring length by 5 mm on the Hardcore, done a manual leveling, disabled the Autobed leveling. Then doing a dual extrusion print sliced with Cura 4.2.1. Z offset plugin is present, set to 0. and Extensive Z
  15. I was having the same configuration + 2 UM3E connected via Ethernet on Cura 4.4. Since I have reverted to 4.2.1 no more disconnects. I have 2 bugs opened on 4.3 and 4.4. They were said by Ultimaker team to contribute to the problem (shadow printers created in background, material issue on projects) @nallath told that the fix will be on 4.5. But it was before the 4.4.1 release.
  16. I've done a fresh install of Cura 4.2.1, removing the user/Application Support/Cura folder from my Mac before making the install. So I should have been able to retrieve the plugin from the Marketplace, as I've done for your plugins without any problem. Is there any other location on macOS for Cura to store the settings and plugins ?
  17. Hi Everything is in the title. I cannot find the RepRapFirmware plugin in the Marketplace, though I have installed it previously on another Cura instance (4.3 and 4.4). I had to downgrade to 4.2.1 with a fresh install due to numerous bugs, but I'm unable to reinstall the plugin. Thanks for your feedback
  18. Due to multiple issues with Cura 4.3 and 4.4 on projects / materials and constant disconnections of the networked printer (though all my printers / devices are on ethernet), I have reverted to Cura 4.2.1 beginning of this week. Since, no more disconnections.
  19. No still the same for a year now. Thanks ! If I have some more informations or a solution, I will post it. BTW my other UM3E doesn't have that issue though I don't care much of the glass plates.
  20. Good to know. Thanks For the moment, I've reverted back to 4.2.1 which doesn't have the issue.
  21. Hi @Crystalvalen I am aware of the connectors issue. I had to repair them on my two UM3E. In fact the sensor is working. A bit too well because it get somehow saturated before the nozzle touches the build plate and detects that the capacitive charge has reached a plateau -> for the printer it has triggered the right height. But it's in the air ..... I have a doubt about the glass plate accumulating too much charge with the 3D Lac coating. I don't clean my glass plates that often and when printing PETG or Nylon I can have a thicker coat.
  22. Here's my 4.3 folder https://www.dropbox.com/sh/5oacccf87icomoy/AACS80n5rcVkErecJEK3KORca?dl=0
