Layer shift when using Breakaway support

[maurice9009 0]

Hi,

I am having issues with my printing.  I am getting layer shifting only when I use breakaway support.  This is currently happing with PLA and PC filament.  If I print without breakaway support I get no layer shifting.  Is their a fix or has anyone else experience this?

thanks

Heyyy @maurice9009,

 

Welcome to the Ultimaker Community 🎉

Do you have a project file for us?
To save a project file go to File -> Save project.

I can take a look at your settings, or try to print it here to see if I'm having the same layer shifting. 
Also, do you have a picture of the shifting? That will help more people who want to help troubleshooting.

Thank you 😄

Hi MariMakes,

Here are the images an 3mf file you ask for.

 

Door Mount with Fillet images the layer shift at the bottom and something towards the top of the print.  Polycarbonate with Breakaway support.

 

Door bracket-fillet images is a different file but printed with the same filament, Polycarbonate no support.

 

Bracket images are printed with PLA and breakaway support has layer shifting.

 

This leads me to believe that its something with breakaway and my settings but i don't know what.

 

Thank You,

Hey @maurice9009

 

Thanks for the files. 
 

I took a look and I already see a potential problem. 
Your profile seems to be based on an not-supported quality type. 
That means that there is a large chance that your slice might be based on the most basic PLA profile that we have instead of the Ultimaker Settings that are a result from days and days of testing from our Profile Experts. 
It might be helpful to redo the profile but use the Fast 0.2 Profile as a basis. 

In the profile I also see that there are a number of settings changed that I personally wouldn't be confident in changing unless I've tested that they will indeed improve my printjob. 


I started the printjob on my S5, I can show you tomorrow if I'm having any layer shifting. 
If that's the case than it's related to the settings. If I don't see any shifting it might be related to something that is wrong in your hardware like the clips not gripping your buildplate correctly.

Fingers crossed 🤞

Thanks for looking into this.  I made the changes because I was printing Ultimaker PC filament.  I was told to print somewhat slow and have a huge brim and glue.  As for the layer shifting, I determined it was the supports.  I added a support blocker for the holes and that took care of it.
