Cura gcode problems

Recommended Posts

Posted · Cura gcode problems

Ive been having problems with Cura ever since I upgraded to 5.3.1 from the 4.8 that came with my Elegoo Neptune 3 plus

I have made little or no changes to the out of the box package. I have chosen PLA, 0.2mm layer, 100% fill (the component is essentially flat and 2mm thick)

I went for raft the phot on the left shows the raft printed perfectly and then the filament just touches down semi randomly althogh it repeats the pattern several times.

In desperation I downloaded Prusa Slicer 2.5.2 and sliced the same .stl file with the same options which printed perfectly (although removing the raft was a nightmare)

Any suggestions as to how I might diagnose the problem? Clearly going through the gcode line by line is not something I can do without knowing what to look for. The slice by slice view in Cura shows no hint of a problem in the layer after the raft.

    It's likely in your settings (there are a lot of settings).  Load the model, set Cura up to slice, use the "File | Save Project" command and post that 3mf file here.

    Look at "Wall Order" in 5.3.1.  There was no such thing in 4.8 and many printers struggle when the wall order is "Outside to Inside".

    Those travel lines look like extrusions rather than strings.  Make sure "Spiralize" is turned off.

    The version of Cura which comes on memory card with Elegoo Neptune 3 plus is definately designated 4.8.0 but that is reall of no interest since I followed the upgrade to 5.3.1. 

    .3mf file attached thanks regards Dave

    The nozzle for the printer is listed as a 0.4 and here are the line widths from your setup.



    In addition, you have the Minimum Line Width at 0.34 which is a contradiction since you are asking for .2 (and a .1) line width.

    I don't know what you are using for a build plate, but this piece should absolutely not need a raft.  It has good surface contact and should stick.  

    At any rate, I made some changes and here it is back at you.

    I'm going to guess it's the front wall of a steam locomotive cab?
