Skipping on layer 74 using cura, doesnt skip using other slicers

Recommended Posts

on layer 74 it stops printing and skips to the next layer, i know this because i imported my gcode into a model viewer and i can see where it just skips the layer. if i use slic3r for example it doesnt do that. ive tried uninstalling cura a few times and nothing has changed. how do i fix this? 

cura dragon.gcode

slic3r dragon.gcode

The first thing to check is to look at the model in "xray" mode to see if there is any red color near "layer 74".  If so then your model isn't manifold.


Even if you see no red I would try sending the model through the netfabb free repair service (you have to create an account but it's quick and free).


netfabb free repair service is here:


Did you create this model?  If so what cad software did you use?  There's lots of ways to make sure your model is manifold in the future.  In particular sketchup is really bad at making manifold models but there are lots of great tools and tricks to overcome it's limitations.
