I am printing on an ultimaker with CURA. I’ve just started with it and have learned something new with each new print…I need help with this issue.

When I load multiple pieces to be printed, is there a way to make it print one at a time. It did this at first, but then the next time I tried to print several pieces, it worked on layers of each piece simultaneously.

The smaller pieces pulled away from the platform (I think because of the way they were then cooling in between new layers) This never happened when it finished one piece before moving to another. I just don’t know what I did to make it work on multiple pieces at once or how to make it stop doing that.

Thanks for your help.

I think that’s standard procedure to print everything on the build plate all at once. If you don’t then the hotend and or cooling fan probability will hit the completed models while printing the new one. I know it would on mine. Unless you are only printing something that is only 5 or so layers high.

@Wayne_Friedt other slicers can build 1 object at a time. In Slic3r you just input the radius to avoid, and the plater will position things for you appropriately. Not sure if Cura ever did this though. I don’t remember seeing it as an option.

I learned if one piece is higher than the distance between nozzle and y- or x-axis rod then ultimaker print all pieces simultaneous. Maybe thats the case…

in Skeinforge the settings for this are called ‘Tower’, I think. I haven’t played with anything but Slic3r in a while, though.

That’s really cool i will check this out, This is what i love about this site. Always learning something new, Thanks

Cura has the option to do it as well. If I was at home I would have a look and tell you where to find it.

They need to be a certain distance apart to do that. You can switch the view to layer mode and move up and down the layers and see if it will print them one at a time or all together.

Look in your menus up top. There is something there for printing all at once or one at a time. It may be under project build or something like that.

This video has some tips for using Cura, about 5 minutes in explains printing individual items. http://vimeo.com/68961154

Back to real problem - the small part got ripped off the bed. Sometime nozzle lift and retraction can help by making sure the head isn’t still attached the the part when it takes of in high speed move to next part. Also slowing the non-extruding move speed may help.

Sadly, Cura doesn’t have a lift-during-retraction option.

Thanks for the responses.
I could not find a menu option for printing one at a time, but I will watch the video in case I am just overlooking it.

I did find that if I deleted the taller pieces, it went back to printing one at a time on its own.

@Lisa_Devillez there is a height limit of the objects that you can print one at a time - or else the object will collide with the gantry rods when the build plate raises for the next print.

Maybe you load one stl file with seperate pieces in there. Mouse right click the pieces an seperate them in the menu. Than it will be print one by one if it can…
