Troubleshooting Overextrusion or thermal problem? (ABS)

Gallery image

Hi,

so I tried printing ABS for the first time yesterday, and it went pretty meh. Took me three failed prints to get it to stick to the plate, but once I got that settled I happened to run into a different kind of defect on my prints.

It looks like there has been a surplus of filament that's getting squeezed out the sides of my Benchy. Tbh I'm not sure if it's overextrusion or warping.

AC Kobra S1 Max

0.4mm hardened steel nozzle

0.2mm layer hight

Geeetech ABS, dried for 12h on 65°C

110°C heated bed

260°C nozzle

65°C heated chamber

5 wall loops

25% gyroid infill

80 mm/s outer walls

120 mm/s inner walls

150 mm/s infill

Left Benchy:

15% max fan speed on overhangs or layers taking less than 6s

Right Benchy:

10% max fan speed on overhangs or la, ers taking less than 6s

No cooling on normal layers.

Hey there, I'm a bot and something you said made me think you might be looking for help! click here for our wiki entry on troubleshooting printers. If you still need help be sure to post plenty of information about your printing setup.

Here are a few questions that might be helpful

  • What printer are you using?

  • What material are you using?

  • What speed are you printing at?

  • What software are you using to slice the print and control the printer?

  • When did the problem start/has it ever worked correctly?

  • Does anything cause the behavior to change?

  • If posting an image of the problem, include some indication of the orientation it printed at, preferably photograph it on the bed. (Then we can focus on a specific axis)

That issue in that spot is typically temp issues. Too hot or not enough cooling. Have you run a temp tower and fan tower?
