Cura 3.5 getting brittle 3d prints

[zephar 1]

I upgraded to 3.5 and at first I thought it was my printer. the prints come out like their missing filament and you can crush em in your hand like an eggshell. I dont get it exact same settings on 3.4 and the prints come out normal. (I did move my settings from 3.4 to the 3.5 would this have caused the issue?

Anyone else had this issue and know what I need to change on 3.5?

 

Thanks in advance and sorry not sure what details may be realevent to the issue I am having.

Hello @zephar, could you please save a project that is showing this problem and attach the .3mf to this thread so we can look at the settings. Thanks.

OH I appologize, I was not sure what to attach or not. Here is one of them that it goofed up on that I did print on the older version.

Did you get this issue resolved?

 

I am getting the exact same thing. I have a Prusa clone running Marlin. I have tried slicing on different workstations with different versions of Cura but get the same results. This started after re-calibrating my Extruder steps. It is 100% accurately calibrated. Other slicers work perfectly. I have tried adjusting the filament diameter on my printer profile in Cura but this does not resolve the issue.

 

Surely this must be firmware related, but why does other slicers work then?

Hi @Zephar, sorry, I have only just seen your reply. That file is just the model, I need the whole project which you can save using the file menu. Thanks.

@smartavionics my appologies I must of hit export instead of save before. hopefully that has everything you need.

 

@SkilletZA Yeah its doing very similar to that, but they look a bit more put together. Works fine on 3.41 but 3.5 and its a mess. =(

Hi @zephar, thanks for the project file. I have loaded that and the layer view looks OK. I will print it on my printer (a different printer but I will use similar settings). Your machine settings are showing a filament diameter of 2.85. That is correct for your printer? If not, that's would explain what you are seeing.

Thats really strange that it changed. As I copied the files over from my 3.4.1. I wounder how a setting would change like that. I will have to later today see what happens now.

I do not want to hi-jack your thread, but maybe my issue can help resolve yours....

Just really strange. It does the same thing.

 

Should I maybe delete and then manually make the settings maybe the settings in the old version are not compatible with the newer version. it the break in the picture was me accidentally breakin git getting it off. its just really wierd.

CFFFP_Frame_L_V2.3mf

I got it figured out, not sure why but it had a printer2 profile instead of the one I made. So I deleted it and used the one I had before. No clue where other one came from really strange. Thanks for all your help.

Hi @SkilletZA, could you please save the project file (.3mf) and attach to this thread as that contains everything in one neat package. Thanks.

I get the same issues, I made a custom fdm printer with .4 nozzle  and 1.75 filament, I changed my filament to a custom 1.75 filament and when i do it tells me its not compatible. No matter where I change the filament size it still prints this way with 3.5. in 3.4.1 i change it and the side bar and all it good. I uninstalled all versions of cura and just reinstalled 3.5 (twice) using a custom printer with the correct settings and still get massive under extrusion. It won't even connect the lines on the first layer they are so thin.
