Dear Sir,
It is first time to print ABS on my UM2 EXT. I have installed Front Door and Top Cover to keep the ambient/enclosure temperature.
Overall print out is acceptable , but the upper part of the print out is deformed . I have to enable the part-cooling / lower the nozzle temperature / speed down the print speed to fix the problem?
Nozzle : 215°C
Bed : 100°C
Layer : 0.2mm
Enclosure temperature : ~40°C
Slicer Cura : Latest Version
Print Speed : 60mm/s
Cooling : OFF
Regards,
Jacky
