Shiny spots on top surface ASA on Flashforge Creator 5 Pro (OrcaSlicer)

[u/Ozmet56]

I'm getting uneven glossy spots on the top flat surface of my print .

This are my printer & print settings:

• Printer: Flashforge Creator 5 Pro
• Slicer: OrcaSlicer 2.5.0-dev
• Filament:JAMHE ASA
• Nozzle Temperature: 265 °C
• Bed Temperature: 105 °C
• Chamber Temperature: 50 °C
• First Layer Height: 0.25 mm
• Top Surface Line Width: 0.42 mm
• Exhaust / Filter Fan: 60%
• Retraction: 0.8 mm at 30 mm/s (1800 mm/min)
• Pressure Advance: 0.03

I tried reducing temp to 250 and 245.

Increasing the min fan speed.

tried ironing and i got a worse experience

In Orca's Preview, show only the affected top layer and switch the view to Speed. Check whether any color changes line up with the shiny patches; that checks the planned speeds without changing your print settings.

This is actual speed, its not exactly the same spots

Orca calculates that 'Actual Speed' preview from the G-code, so it isn't a live measurement of the printer. Since it doesn't line up with the patches, these images don't establish the cause, and I wouldn't change temperature or flow on that basis.

Those look like low spots, if we're talking about the bottom left corner going up to top left.
