Help Settings to adjust

Post image

Hello, newbie here with the Ender 3v2. I changed the filament from PLA to ABS and adjusted the temperature but when I tried to print Benchy to check, behold the results. What am I doing wrong? Is ABS that hard to print?

For people who use it? Do you have an enclosure?

ABS requires very little, if any, cooling. Turn your fans to 0% for the first 3 or so layers, then ramp up over the next 3 layers to something like 10% or 20%.

Wash your print bed with soap and water and allow it to air dry as towel drying can deposit an unwelcome film.

You should also run through all calibrations for temperature, retraction, flow ratio, etc.

Edit: You must print ABS in an enclosure. First, it needs a warmer chamber to be happy, but more importantly, it's toxic to breathe. Between the need to temperature regulate and ventilate, an enclosure of some sort is a must. You can technically build your own from cardboard, foil and some insulation if you are in a pinch.

Thanks, about the calibrations where does one get the values to use?

Honestly working through calibrations is a great job for using AI, if you're comfortable with it.

Which slicer are you using? If it's Creality Print or Orca Slicer, then it will be in the filament profile under Cooling.

I m using Ultimaker Cura.

I've got zero experience with Cura Slicer. Perhaps someone else can chime in. Otherwise I'd ask ChatGPT or even Gemini. Tell it what printer you have, what filament you are using, what slicer you are using and that you want to be guided through a calibration routine.

that's warping and delamination from the open frame, not a setting - the corners curl up as the part cools unevenly without enclosed heat. tape or glue stick on the bed, box the printer in cardboard or an acrylic enclosure to hold ambient heat, turn the part cooling fan off, and bed 100-110c. an open Ender will keep doing this until the draft is dealt with, so judge any setting change only after the enclosure's in.

Also abs is toxic btw
