#ABS Warping

After doing Ellis' tunning guide, I managed to get near-perfect small parts. However when printing a large part (250x230x110) I got this result.
I printed it using eSun ABS+ at 100 degrees bed temp and 240 nozzle temp. As you can see, there's a fair bit of warping and cracks. Any ideas?

I also have my Nevermore running at 50% speed

Chamber is too cold. Print temp is too low. Too much cooling.

#

Solutions:

  1. Get chamber temp above 60C. Insulate the printer, install bed fans, throw a blanket over the printer. Go here and learn: https://discord.com/channels/460117602945990666/1021908552702505051
  2. Increase print temp to at least 250C, higher is better, don’t know how high can eSUN ABS+ go, you should go as high as possible while still being able to print overhangs with minimal cooling.
  3. Reduce cooling to 15% for everything. Once chamber temp goes above 50C, increase to 25%. Once chamber temp goes above 60C, increase to 35%. And so on.
