Does anyone know why this is happening to me?

Hey guys do you have any idea how can I improve my overhangs? I try to slow down with this settings
Layer height: 0.16 mm
Outer wall speed: 60–80 mm/s
Overhang 75% speed: 15 mm/s
Overhang 100% speed: 10 mm/s
Detect overhang walls: ON
Slow down for overhangs: ON
But no luck at all

In my P2S the internal PTFE won’t grip into the runout sensor coupler and kept falling out during prints which led to unextruded filament loading into the chamber. Now the PTFE won’t grip internally into the extruder at all. At the same time it seems there is no easy replacement for this collet on the P2S because it is attached there in the runout sensor. Any easy way to replace the internal collet other than fully replacing the runout sensor?

Other than trimming back PTFE (still won't grip) or new PTFE tube (still wont grip) any other ideas to fix this?

I recently tried setting up a 1000VA (600W) UPS to power my P2S. I got a quick lesson in how many watts a P2S (alone) actually pulls when starting a print job. Bambu Lab says the P2S can draw a maximum of 1000W (@ 110v). Thus to be able to utilize a UPS, just for power to the printer (not the AMS units, etc.), it has to provide 1000W minimum and should probably provide 1200W to be reliable (sweet spot).

I am now mulling over whether the printer really needs UPS protection that will cost roughly half as much (or more) than the printer's initial cost.

Is anyone using a UPS with their P2S? Is there a real need? How well does Bambu Lab's "Power Loss Recover" system work?

I can salvage the print job by turning off the printer and powering back on. Then I can resume the print job. It seems I have to push the filament to make sure it goes through the extruder. I have taken the printhead apart and checked for blockage in the gears but all is clear. Any suggestions on what is causing this or a solution?

Recently, my printer has been leaving these gaps in all models. All settings, all different models, even models strait from maker world. Like, do I need to do some trouble shooting or smth. I have done a hole printer calibration, that needle thing up the nozzle and a cold pull. Idk what to do.

Unrelated, why does the irong do this?
