Filament Does Not Stick when Printing Specific Model

[TechAndrew 0]

I'm having an issue with the filament sliding along with the nozzle while printing a specific stl file (attached).

This doesn't happen with any other 3D model I've printed.

 

I suspect there is something wrong with the slicing process.

Hello @TechAndrew. To be able to understand the problem, I need to see the settings. Please save the project file (File->Save) and attach the resulting .3mf file to this thread. Thanks.

Thanks for the file. Looking at the layer view, the first thing that strikes me is that the model isn't flat on the build plate because you can see there is a wedge of support under part of the model. That can't be helping the adhesion.

 

Secondly, it's still printing the first layer at 25 mm/S which doesn't sound very fast but given that the model has some fairly sharp bends in the walls is probably too fast. I would try 15 mm/S or even 10 for the first layer speed.

 

Thirdly, it's worth enabling the optimize wall printing order setting.

 

Fourthly, you may want to use a thicker layer for the first layer as that can also help adhesion.

 

Hope this helps!
