Need Help. Poor ABS 3D Print Quality After Core Change

Recommended Posts

Posted · Need Help. Poor ABS 3D Print Quality After Core Change

Need help on what settings do I need to change to make this print with crisp edges again.  I had to replace the print core due to the brass heads being worn out and before the replace heads I had no problems printing this design.  All sides had clean edges before but now the bottom edge is very rough and this is the same profile that I was using before.  Here is my set up: 


Ultimaker S5

Matterhacker ABS Black (I have tried several different brand new rolls)

Printing Profile: Engineering-Normal 0.15mm

Printing Temperature 235 (Used a temp tower to determine best temp)

Infill Density is 20%

Building Plate is 95C

Print Speed is 30mm/s

Everything else is the stock settings.
