Hi, keep making this a issue so Snapmaker evolves Snorca to support technical filaments.
First the default Generic ASA setting were very poor and so I ran a temperature tuning profile using orca slicer for Elegoo ASA filament and found 270C and zero fan works best.
Back to your comment.
Inside the ASA profile I put this gcode to make the bed temperature to 100C and wait 30min.
M140 S100 ; Set bed temperature to 100C and continue immediately
M190 S100 ; Wait for bed to reach 100C before moving to next line
G4 S1800 ; Dwell (wait/hold) for 1800 seconds (30 minutes).
I am printing right now so will keep you updated.
