Hi 

 

We are using Cura and STL files for printing. if you look at the pictures below, I have a phantom design and support which is making it take longer to print. This is happening on all my past designs, how do I get rid or what to do. Please help. I am using another computer to print not the main computer.

    I'm not sure I understand the question. Do you want to get rid of the support (the blue semi transparent stuff in your 2nd screenshot), because it adds to the printing time?

    Do you understand what the support is for?

    They (likely) want to get rid of the cylindrical prime tower, and the supports that extend beyond the model on the left and right side (caused by the Horizontal Support Expansion, which has a default positive value for PVA supports).

     

    When using default settings, it may not be obvious for a user why a certain value is set that way. Why is there a prime tower, and why do PVA supports print "a bit wider" than what looks like is needed. Setting values intended to improve (certain) prints may not be obvious to a user and may look unnecessary.

    Hi

    thank you for your replies but I have checked the Enable prime tower" and "Support horizontal expansion and these are not on. I have put the extrud 2 nozzle back to PVA and the tower disappears from the design, but in nozzle 2 we are running PLA as we really struggle with the PVA blocking up and not working properly. The Computer I use has support material set to nozzle 2 but in our work shop they are set to only print with one nozzle even though there is two. I will keep an eye out for it again. when running PLA through the BB08 nozzle I have to over ride it when it starts printing. could this be the problem.
