Not printing walls, only infill


Recommended Posts

Posted · Not printing walls, only infill

I'm use an Ender 3 pro but all my prints are printing the internal lattice work only. Is there a way to fix this? attached is that I want, what I got and the gcode of how I got there. the slicer makes it appear that everything i fine.

    There isn't anything wrong with the gcode.  Your printer is under-extruding by a lot.  I happen to also have an Ender 3 Pro and it's a problem that showed up a couple of times.

    Starting at the beginning:

    • The filament spool needs to move freely.  No loops or snags on the spool.
    • If you have a plastic pressure arm on the extruder they have an amazing failure rate of 100% and when it cracks at the pivot point the arm doesn't put enough pressure on the filament to move it to the hot end.
    • The hot end itself can develop a gap between the bowden tube and the back end of the nozzle.  If it does then molten plastic can get pulled into the gap by retractions.  The plastic hardens and forms an o-ring sort of partial blockage and after printing for a little while under-extrusion starts.  I can almost talk myself into seeing that with the brim of your print.
    • Not very popular but not completely unknown (it happened to me) is a bad stepper driver on the main board.

    If it isn't a broken pressure arm then it time for maintenance on the hot end.  Warm it up to get the nozzle out.  Take it apart and clean it out.  Trim the bowden tube back by about 6mm (with a nice square cut) and put it back together.  Warm it up again to get the nozzle back in.  It should be snug.

     

    My printer came with a 1.1.4 "loud" board.  I had the machine a month or so and it was driving me nuts so I ordered the 1.1.5 "silent" board.  The first one had the E stepper driver fail after 1 week.

    Another time the under-extrusion started the problem was the not end.  After fooling with it a bunch of times I went with an "all-metal" hot end.

    My wall problem appeared after the 5.7 update installation. These are my prints the red before the update, blue after. I’ve added density and walls but still get the blue outcome. 
    Anything will help.

    Thank you.

    If something works fine in an earlier version but doesn't print correctly when sliced in 5.7, then you should submit a bug report. Make sure to include a Cura project file of the same model saved from each version (you can have as many versions of Cura as you want installed side by side, so you don't need to downgrade or anything) as well as the gcode from each version, and preferably photos of it printed from each gcode (it doesn't need to be a big model, just anything that will demonstrate the problem).

    The printer is as Ender 3 S1 Pro so not the same as was stated and it appears to be a direct drive so not a bowden printer.

    I read the gcode into MS Excel to do the analysis of the extrusions.  There is no problem within the gcode.

     

    I altered the temperatures and changed the retraction distance from 0.8 to 6.5 and it printed fine on my machine.

    @muscato57 you are always welcome to post a bug report on GitHub.  I do much of the triage over there and I would perform the same investigation there that I did here.  I just don't see any problem within the gcode you posted.
