  1. Well spotted, I didnt realise that infill steps and infil line multiplier should normally be mutually exclusive. For anyone reading; it appears this bug was allowing me to edit gradual infill steps AND infill line multiplier at the same time, when normally editing 1 of those settings would hide the other setting.
  2. I've attached my cura profile if that helps ratt bug profile.curaprofile
  3. Hi Thanks for replying. I've attached the 3mf file. Also this happens on every infill pattern I've tried so far, lines, grid, triangles. Also attached my infill settings Model was created using fusion360 with medium refinement (Dont think thats relevant as I've never had any issues before) CE3E3V2_belt sander dolly v3.3mf
  4. I'm running into an issue with my Ender 3 having extruder skipping. I've had extruder skipping before but only on the first layer due to leveling the bed to close to the nozzle. However I'm getting this issue later on in the print. A good few layers later, in the same place each time. So its not bed level related. In this example I'm printing something like a thread bobbin, like a cylinder. So nothing crazy. And its only happening during certain parts of a certain print. I was printing with this exact same setup just a few days, and have been printing this way for years with no issue. Petg 225'c 50mms (I turned down the speed mid print to 20% but it still skips, so not speed related) It's not during the first layer, so bed spacing is fine. Nozzle isn't clogged Bowden is secure Extruder gear is fine. Filament is fine and not chewed up. Spool rotates freely it's on a ball bearing mount I tried turning down flow rate to 80% mid print on the parts its skipping on and it continues to skip but less frequently. It does it on both cura 5.2 and 5.3.1 THE PROBLEM: As you can see from the G-code in cura / the video below. It prints the first 4 layers no issue. The skipping issue starts on layer 5, the outer walls and inner walls print fine, then there are these thin bits of infil which are spaced slightly inwards from the wall. And as you can see the nozzle goes over and over the same spot multiple times, and this is where the extruder starts skipping. Which is why I think its blocking the nozzle and causing extruder skipping. The issue then stops and prints the green/red lines fine, and then restarts again on layer 6 when it goes to the infill part again. Heres the video, look at the orange lines (infil) The gcode is attached if you want to look at it yourself. I've tried other infil patterns and a similar thing is happening, the inner infil goes over themselves multiple times. Thoughts? notfixedbobbin.gcode
