S5: Unnecessary drive to Print-Head change

Recommended Posts

Posted · S5: Unnecessary drive to Print-Head change


I work with latest Cura 5.2.0 and latest firmware of S5.

In my job are 4 different parts (attached). Until about 15% of the highness there is the second printer head necessary for the support of Breakaway.

Above of 15% there would be only head 1 necessare because there is no breakaway needed.

But the head is each layer driving to the right side and switch to head 2, switches immediately back to head one and prints the next layer.

This needs a lot of time. Have I made a mistake in the configuration?

Please check this situation.

Thank you and regards,

    This sounds like a new bug.  Please post it on github to be sure you get the attention of the cura developers.  Post the 3mf file but don't post the ufp file. 


    After you create the issue, post a link to the github issue here and I'll add a comment over on github to help it get attention.


    Unfortunately you have to create a github account if you don't already have one but it's free.

    @Manfred_Schwarz - I think you misunderstood.  Me also.


    The support is doing something - it is supporting that super tiny ledge near the top of the tallest part.


    I changed the support overhang angle from 45 to 60 and now it doesn't support that tiny ledge.  That's all you need to do.  I thought you found some new bug.  You should close that issue over on github.  You could also use a support blocker.  Really only one of the 4 parts need support and I see you put support blocker in that tiny hole which is smart.  You could have used a support blocker on the tall piece as well.  It doesn't need any support.
