Print quality elegoo Neptune 3 max

I’ve been trying to fix this issue for a while now. (See attached image) I have tried leveling the bed multiple times, changing z offset, and adjusting flow rate non seem to help! Any suggestions are helpful!!!!!

Your print has under-extrusion issues. To fix it, try these steps:
Clean the nozzle, check the extruder for slipping, use fresh filament, and raise the nozzle temperature by 5–10°C. This should improve the print quality. My suggestion

[cinder spruce]

After carefully inspecting the nozzle and increasing temp still no head way on fixing the under extrusion

[cinder spruce]

This is temp at 240 and flow rate at 150%

Since you're still getting under-extrusion at 240°C and 150% flow, it's likely a hardware issue. Check for a partial nozzle clog, worn or loose PTFE tube, extruder gear slipping, or bad filament—try a new roll to rule that out.

Printer has no ptfe tube filament is fairly new. How does one check for gear slipping

[worldly trail]

Mark the filament, run extrusion—if the mark barely moves, the gear might be slipping. Check if the gear is tight and clean.

[cinder spruce]

Definitely not slipping the mark moved normally. Hmmmm

[worldly trail]

If the gear isn’t slipping, it might be a partial nozzle clog or heat creep. Try a cold pull, clean or replace the nozzle, and test with a fresh filament roll.

[cinder spruce]

Cold pull and fresh filament still didn’t fix the issue!!!!

[worldly trail]

Since cold pull and new filament didn’t work, check the extruder motor for skipping, try a new nozzle, and confirm the hotend is reaching the right temp, could be a misreading.

@cinder spruce what do you mean with 150% flow? i cannot find that flow variable in Cura, Orca or bambu studio.

[cinder spruce]

For simplicity of testing I increased flow rate on the printer it has the option
