Speed Settings for Small Infill


Recommended Posts

Posted · Speed Settings for Small Infill

Attached is a screenshot of the layer with the problem. The very small diagonal infill is causing severe vibration of the X and Y axes on my printer so it looses steps in both directions.

I have printing speed set to 50mm/s and none of the other speed settings enabled. What speed setting can I change to slow down this part of the printing without affecting the speed of the rest of the print? Or perhaps there is a kinder acceleration setting?

    While waiting for my post to be approved it looks like I might have found the solution. It seems the default travel jerk setting in Cura is too high for an Ender 3 Pro. I've reduced it to 10mm/s and everything so far is much smoother.

    Or I think you can just uncheck "jerk control" and "acceleration control".



    I had to check "jerk control" - it was hidden and unchecked. So maybe this default configuration in Cura uses some poor default in the firmware.

    If you disable jerk and/or acceleration control it should use the defaults on the printer itself.  Which might be set too high.  Most printer's these days use some version of Marlin and some versions of Marlin let you set motion parameters in the menu system.  Things like max speed, acceleration, jerk.  For each axis.
