@ultiarjan @Smithy @foehnsturm or @RudydG Maybe one of you still has the stl file?

So the (a bit postponed) reaction to this, is that materials are only removed from the printer if all materials are unloaded from the material station. Then after a factory reset all materials are removed. To debate further on this: I did manage to find a conflicting GUID in Cura vs. printer material. My guess is (I didn't deliberately test this) that when you change some settings to the material properties in Cura (my guess is: the name or the material type) it will keep the same GUID, but the 'old' unchanged material with the same GUID is still in the printer. So when you try synchronizing the materials it conflicts and apparently this conflict is not resolved in the synching process, so it spins forever actually doing nothing.... So conclusion: It's a synching issue (duh) meaning it's both parties involved (Cura and Printer). @MariMakes for this one to pick up by the team? Hinting at a solution would be to always change GUID in Cura if user changes material name, material type or some other fundamental. Then when synching comparing the materials from Cura with the ones in the printer and if 95% of the properties of a material are the same (but having different GUID's) it could ask if user wants to replace this material with the (a) new one... In the meantime for users either try the workflow mentioned above. Or factory reset the machine and resync materials (annoying yes, hell yes)

Thanks again @Masterdark for taking the effort to reply and help out! I have reset the printer to factory settings but unfortunately (in most cases this is wanted off course 😉 ) the materials aren't removed. So now I will try to guess what material it could be and will try to delete those. I'm also going to make a support request for this at Ultimaker. I will post here what comes out.....

I'm really interested if someone can raise some light on the previous post. I switched to build tak with PEI sheet on my S5, wich work really well, but the hot nozzle digs into the PEI sheet in the first probe of the auto leveling procedure. So my questions are in the preferenced order: 1) Is it possible to set the maximum temp of the nozzle for the auto leveling procedure? OR 2) Is is possible to add a wipe somewhere before it starts the auto leveling procedure? OR 3) Is it possible to move the location of the first probe? AND 4) Is the first probe part of the height data gathering or is it to roughly determine the height for the rest of the procedure?

@Masterdark thanks again for sharing your workflow. Considering you do it that way tells me that this is typically a bug that can be fixed rather simple in the firmware. Something to report to Ultimaker I guess? Question remains; for anyone out there who can answer this: How to delete all materials , including hidden ones, from the firmware? Or: How can I renew all GUID's of all materials, considering this will fix it to....

Would like to try this, but the posted STL file link is dead. Can @foehnsturm post it in Thingyverse? thanks in advance!

@Masterdark: Thank you! I've read the work around and understand it. I'm pretty sure that will work, but the thing is that I don't know what GUID/material is causing it (I just started in 3D printing with my recently bought S5 so i've been fiddeling around with setting and materials). And as I understand from the post even the API is not listing the 'phantom' material. Will it work if I reset the printer firmware to factory settings? Are all materials (even phantom) deleted then? I that works, then I can sychronise the materials between Cura and the printer again. But what can I do to prevent introducing the problem again? What can I look for and correct in the list of materials in Cura?

Also having the exact same issues and tried both workflows: USB and Cura sync. Both don't work. S5 Cura 5.5.0 Firmware 8.3.0 -------------- Update: Updated to Cura 5.6.0 stable Followed the exact workflow here: https://support.ultimaker.com/s/article/1667410781024 But now, when I try to import one of the suggested custom profiles, it shuts down Cura....
