Since I've had this printer I have not been able to print good ABS prints. My PLA prints are pretty decent. I have no issues with bed adhesion, but each layer is wavy and the head is knocking of little pieces of the print. Currently my nozzle temp is 235c and my bed temp is 80c. I have tried cooling fan both on and off and it seems to make no difference. Please help.
