It works ok, but I did a calibrate, again. It does seem to help. Thanks!

Hi UM folks, I get a "Nozzle offset test failed"message with every, really every print I do. And nearly all of my prints are using only one extruder. I uncheck the other extruder in Cura when slicing, so what the other extruder does is totally irrelevant. I installed the latest firmware on my UM3, and it still happens. Does anybody have an idea why this is happening? thanks.

Hi all, I fixed it. Re-installed firmware and did the lift switch calibration. The latter was the culprit. Only problem left is that the front door of the print head will not close anymore. Steel wire to the rescue. No back to the "normal"printing problems.

The first 20 or so layers were still attached when I found the mess. I use a salt solution and it attaches extremely well as long as the build plate is hot. But I did find the small bits of silicone that the nozzles poge through were out of place because oif a blob of resin. After I placed them back properly, cleaned the print cores and bent the print head door back to it closes again, I can print.

First layer was OK so I went out to lunch. Coming back, the buildplate was moved 10mm to the side and the print head door was open. After removing the print cores and with some bending, I manages to close the door again, but with the cores in it it will not close. No idea why this was happening, but from the remains of the print I can see some huge layer shifting. No idea why this happens, but my printer has broken itself and I have work to do 😰

@Cuq Thanks, that did it. I had no idea there was any right click options with the support block. Have a nice day!

Hi, folks. I find that when I use the support blocker while having extruder 1 disabled/ extruder2 enabled, I cannot slice. It says: unable to slice because there are objects associated with disabled Extruder 1. believe me. nothing is associated with extruder 1. As soon as I remove the support blocker, I can slice again for extruder2. Stuff I am using: Cura 4.11.0 / UM 3/ rPETG. greetings to all, Maarten

Hi Torgeir I keep all my filaments in a closed box, in wchich I also throw all by bags of silica gel. But I solved it. 1. installed laters firmware, 2 found the filament had been grinding because I set the 1st layer height too low, so removed that langth of filament 3 cleanied out the printcore. 4. I am printing again! have a nice day and thanks Torgeir, just when you want to bang your head on the wall, a helpfull community really gives peace of mind. cheers, Maarten

Hi gdog, thanks fot your input, but no figurine here. It's quite a large object, no figurine. I only added the brim because I had adhesion problems in earlier attempts with this print. I am ordering some fresh material as the filament could be the problem. Been printing abjects like this fore years, but I just changed to another roll of filament whach had been out of its package for a while. thanks anyway, Maarten

Hi Torgeir, I realise I was wrong about s3. hadnt realised as such they were different printers. But I do have an Ultimaker 3, and Cura is set to UM3, so that's in order. I have attached the project. so you can have a look. regards, Maarten SN project.3mf

Thanks Torgeir, I am away from printer now , will do asap. cheers, Maarten

Hi, I am printing with tPLA on my S3. Used to go fine until I tried to print this. Been pulling out my hairs all day. I set temp to 225, and initial layer height at 0.15. (tried other heights too, nothing works), Supports everywhere, brim. With hand leveling the first layer does not attach, with active leveling is mostly does. But after that I get only a few poor little sprigs instead of harmonica support structure. Could anyone tell me what's going on? Filament is original UM. Thanks, Maarten

I have the same problem. Cura does not "see "sd card or flash drive, and also sdaves to a random location (like "thinking" my cloud storage is a sd card) . Cura is great, but ist time the programmers adress this issue. cheers, Maarten

Enigma_M4 I had not managed to find that thread with the forum search. But the CarloK solution simply sorted it out. so: many thanks! Maarten

Hi everybody, I had this nag message that I should not print tPLA on a BB printcore. Cool, but I am not doing that so stop reminding me. Then I "changed printcores" . I took out the AA, waited, and put it back in. UM3 says a BB printcore was inserted. So UM3 thinks I have an AA printcore at extruder1, while really there is an AA present. Someone knows whats going on? BTW, prints fine. best rtegards, Maarten
