S5 Heavy Vibration When Using Gyroid Infill

[JVorders 0]

Hi All

 

I've tried using the gyroid infill setting a few times now and each time have experienced an alarming level of vibration at the print head that comes when the infill is being printed. I can't tell if this is due to the slice settings or some kind of mechanical issue e.g the nozzle tip catching against the material, but either way it doesn't seem like it'll be good for the printer over time.

 

The problem doesn't exist on the first layer, when I've printed an infill-only model, but it always occurs on each infill layer after that. I have attached a video with sound of a part exhibiting this problem, and the Cura project file. Could anyone shed some light on whether this is normal, or what the problem could be?

 

Many thanks.

The first layer is almost always printed slower than the rest of the model by default.  Try slowing down the speed of the infill and especially the jerk and travel settings.  I find that many of the default travel and jerk setting in Cura result in rather violent head motions with my UM3 machines.
