File is breaking 2 of my Ultimakers! No materials come out

[sharahamo 0]

I was trying to print something, but unfortunately, the material did not come out at all after a few layers (few mm thick). After that, when I try to print something, no materials come out. I tried to clean the nozzle using the atomic method and opening up the parts to make sure the nozzle is clean. But the material still did not come out.

Giving up, I tried with another Ultimaker (we had 2 UM) and the same thing happened again!! First few layers was fine until a few mm thick where the materials did not come out anymore. I guess my gcode is making the UM broken. But now even I try to print another part, still not working. It was working fine before. Help meee :(now 2 Ultimakers gone.

Which version of Cura were you using? If it was cura 2.5 beta, please download the latest beta.

Please share your gcode and project file.

best guess is too many retractions have eaten thru your filament, when the knurled wheel pushes and pulls to many times on one area it starts to fall apart.. re slice it with less retractions after you change the filament out! good luck!!
