Hardened steel nozzle with Wood PLA studdering

I am working on some prints with wood PLA. I replaced the nozzle with a .6 mm hardened steel nozzle. The print goes well until it starts a wall that has vertical infill. Once it starts printing the sides, it starts to "stutter", moving back and forth really quick. It did not do this with the brass nozzle - it only started happening once I switched to the hardened steel nozzle. The outline of the edges is fine (see attached picture on right) - its when it starts to fill in the middle of the sides that it starts to stutter. I have tried increasing the heat as I read that the hardened steel does not conduct heat as well. I also reduced the infill to 0%.  You can also see little "divots" where it is filling in (see attached picture, on left). I am not sure what settings I need to alter to correct this? Any ideas or help would be appreciated!

What do you mean by stuttering ?  DO you mean the nozzle/extruder is moving back and forth quickly or do you mean the filament flow is uneven ?

Also can you please save your project (File > Save As) and then zip up the saved .3mf file and attach it here.  It needs to be in a zip or the forum wont accept it.  That way we can see the model, see what settings you are using and also slice it and study the preview for any obvious issues.

Hello! The nozzle is moving back and forth very quickly. I am using Simplify3D and do not see an option for .3mf.  Would the .factory file work?

Sorry can’t help you with s3d as I don’t own copy. You might have more help if you changed the title to reflect that you need help with s3d slicing settings. I assume you changed the settings in s3d to define using a 0.6mm nozzle ?  Once you do that then the slicing parameters will change as the extrusion width should be set wider to go with the nozzle, that will of course change the slicing as it is likely that there will be less perimeters or less passes for perimeters etc so will effect infill too. Basically everything changes depending on the hardware.
