I think that the ender 3 max has problems with heating the bed evenly.
I see that you are using cubic infill, I read somewhere that rectilinear (zigzag infill) infill is recommended for the lowrider v3. Not sure what settings are the best.
I am also using blue pantiners tape and a bed adhesive. I also have an ender 5 plus at another location with a 0.6 nozzle.
Have you tried other filaments types? I have read that esun pla+ is able to resist higher temp. I have two filament of this brand but I haven´t printed anything with it yet.
I think that a higher ambient temp then 13 degrees C is preferred.
No i have only used pla + . I did order some petg though just incase. The problem was with current setting of the motors (Ryan put me on the right path for setting them) I did however buy heatsinks and fans but i don`t think ill need them at all.
So, I believe pics would be in order? IT all Depends on where the warpage is. There are alot of spots warpage will not hurt at all. But then if it is a critical area, any warpage can cause bearing misalignment, etc.
Those should not matter. Others will be along shortly. As long as they line up and are not significantly out of place. (Now me being me, if they were out of place, I would probably try a heat gun, but my hair brain ideas never work, so I cannot recommend it, LOL)
I just finished a piece with low bed temperature, 45 degrees C at the initial layer (to make the bed ashesive stick) and then lowering the bed temp to ambient room temp.
What filament are you using? If you posted prior, I apologize.
Oops you did. Pla and those conditions should not be doing that. Are there large drafts??? Or are you printing fast? I recently learned if you slowwww your print down it has more time to cool. I think it is in that post above. With speed you need adequate cooling.
