Eh, prusa still seems to be behind the curve, and their insistence on sticking to their old proprietary firmware instead of moving to a more modern approach with klipper and work with the huge community there is IMO a bad move.
Unfortunately they've discontinued the xmax 3, and the newer ones are slightly less open. I would have liked to get a second xmax 3, i got mine for €500 on sale it's been an amazing deal, absolutely insane value for money.
It's a little hard to see due to low resolution, but it looks like you have small gaps between infill lines. If that's the case you need to reduce Z-offset to get more squish.
I would go PET/PETG for everything unless you need the slightly higher temperature deflection of ASA. I have PET prints that have been outside for 2.5 years now with no discoloration or apparent issues in strength.
This isn't a case of "gaming the system" though. "Gaming the system" implies working within the boundaries of it, but in unforeseen (but legal, or at worst slightly questionable) ways, to min/max your output. This dude just committed plain fraud.
Filament buildup on the nozzle is my guess. Could be a Z-offset/first layer squish issue, filament moisture content too high, temp too high (or too low), nozzle hitting print during travel, small amount of oozing during travel moves, worn out nozzle with uneven nozzle shape/diameter, partial clog...there's a number of different things that can cause this.
LDWSs are annoying AF if you drive anywhere with frequent road construction/maintenance...It will vibrate and beep loudly for no fucking reason, giving the drivers fucking jump-scares, because it can't differentiate between the old currently unused white lines and the temporary bright orange ones currently to be used. They're are half-assed solution in place because of poorly written regulation.
Edit: and "newer" implementions are also "active" so they will jerk the steering wheel as well...fucking insane. Our 2020 VW Up has this bullshit, luckily it's easily disabled with a button.
Of course, but inertia in peoples routines and daily life is also immense. They have definitely made some extensive cost/benefit and risk analysis on this scenario.
They're fucked even without tariffs...
