We are printing a very large print with support. The walls are not very thick. It is a mask that covers the persons whole head. The first time we printed this, it had the same separation, but was a lot worse and didn’t make it as far. This time we changed the print head temperature to extrude hotter (from 250 to 260), but had a similar result.
What is the issue? This mask needs to be printed in one piece (as customer requested). We are printing in ABS and upped the temperature to 260 and print bed at 110.
