I can really only recommend trying the Meta PLA. I used to have problems with lifted corners as well, but since I started using Meta PLA, I don't see this anymore.
My only "problem" left is the overall precision of the printer in terms of X/Y/Z orthogonality and calibration, I guess. With the bigger prints I'm typically still off by a few 1/10s of millimeter here and there, but don't have the determination to try to fix this.

What are slower speeds you would recommend? Perimeter are currently printed at 80mm/s, infill at 139mm/s. I can use a percentage value for overhang printing speeds. I would definitely slow down for the last 3-4cm in z-height, if it helps.
No proplem. I have posted some on my thread to the speaker project..
Main issue is the warped print starts hitting the nozzle and at some point it just clogs up....
I had problems with tearing up the print when removing support structures, but have introduced a support interface layer of 0,2mm. No problems since.

Check your amount of extrusion. I had once slight over-extrusion and the problem was similar. After some time nozzle hits more and more until it cracks.
I have calibrated extrusion multiplier using superslicers calibration parts and surfaces etc. are superclean. Maybe its more about speed. What are your settings, just for comparison?
I use PetG recently. But for PLA I used much faster without issues. Maybe follow Mabats recommendation and try another Pla brand
Did you try to heat up the chamber? (Or the other way 🙂 )
Some PLA just warps like crazy no matter what. In this regard I always had a better experience with the cheap stuff.

I'll produce test filament from Smile teeth aligners - TPU 64 Shore D. This material is dead when you knock it. Anyone interested to try? TPU is the only material known to me that prints easily in cold garage, no bed heating. It can maka banana after removal but prints safe and hard to destruct with hammer.
How do you finish the TPU prints?
64 Shore D is already pretty hard I guess - is it comparable to e.g. PLA in this regard?

I put a cardboard box around my printer. My printer is next to a window and direct sunlight made my waveguide petal move by more than a millimeter.

PLA is over 70D. I have impact PET-G from Plastspaw that is much softer. TPU is max 85D. Acoustical properties much different, I printed once Iwata 300 (see below) out of Ravathane 3015 D65 (similar TPU) and my friend cried when do sanding and lacquering. It clogs paper. Just do fuzzy skin and forget post processing.

My workshop has 6m ceilings and is pretty frisky in winter. 16°C is the norm currently. What do you think about decreasing fan speed, similar to printing ABS? Should increase part temperature when the bed temp influence is gone..
I think you said that you have this printer: https://zaxe.com/en/3dprinters/zaxe-x3
By heating up the chamber I meant the interior of the printer. I have only a "semi-open" printer but I can imagine that the chamber temperature can have quite an effect. As for the fan speed, I've never experimeted with that a lot.
- Now I see it's "passive heated chamber", which I don't quite understand. Does it mean that it basically doesn't control the temperature inside the chamber?

No its heating up during the printing process. For ABS and 110°C bed temperature it works out, but PLA with low bed temperatures and a cold workshop seems to be problematic. I will just experiment a little more...
If the chamber heated up just from the bed, without a regulation, that would be strange.
- I keep bed temperature at 55°C for PLA.

If you hit printed parts while travelling: increase z retraction might also help. But it is not the root cause
Got a photo?
First things I would try:
1) Leave the printer door open, if it has a removable lid, take that off as well.
Could be that it's getting warm enough inside to push the PLA over it's glass transition temperature.
2) Second I would try plain PLA (generally had good luck filaments from eSun). Could be that your PLA+ mix a lot of ABS or other plastic that tends to warp in it.
Good luck!
I have another 3 fails of PLA+ and will try open enclosure (lid and door) first, decreasing fan speed ABS style second. If this doesn´t deliver results i will try PLA meta as @mabat suggested. I really want to have a reliable process to be able to build 12" and 15" MEH waveguides for a no compromise speaker project..
I will report back.
