ABS glass fiber orientation type warpage

GF-ABS orientation-type warpage is broken by 'gate design', not by hard pressing with cooling: once the warpage direction is fixed, you should go back and review the gate and orientation, rather than repeatedly trying mold temperatures.

ABS nozzle drool and cold slug marks

ABS drool and cold slug marks often have the 'same source': for drool, first lower the nozzle temperature and add suck-back; cold slug marks rely on the cold slug well to catch the front cold material; both point to nozzle temperature and cold material management.
