How to resolve this blobs external walls problem?
Filament is ASA at 260°C, I’m sure that is not seams. Filament is dry.

  • reduce external walls speed to around 100mm/S or even 70
  • ASA does not like speed above 140 mm/S - all speeds bellow that
  • The above assumes that - Filament is dry and filament is calibrated ( PA, and flow)
