Warping
I've been getting some significant warping on my MK3S+. I've been using PrusaSlicer and either Prusament or Hatchbox Filaments. I've tried:
Bed temp at 60 the entire print
60 first layer than 50 entire print
Print with brim
Any more suggestions?
RE: Warping
I assume this is PLA from the bed temperatures..?
Sometimes reorienting the print on the bed helps, rotate by 45 degrees as a first try.
And try increasing the bed temperature.
If the workspace is cold you might try a temporary enclosure: remove the top and bottom of a large cardboard box and drop it over the printer when working to contain the warm air.
Some photos might help us diagnose problems.
Cheerio,
RE: Warping
What bed you are using? Pei or powder coated bed?
What filament you are using.
Search youtube for tips on warping.
1. Bed not clean, clean bed with dish soap, this the best way to clean, do not use other ways, use a lot of hot water, clean a few times.
2. First layer calibration needs to be 100%.
Both settings are needed for sticking to the bed.
Extra is a big brim attach to model, disable elephant foot, use glue stick if needed.
Warping, 1 en 2 tips needs to be 100%.
Print with a draft shield, is a slicer setting.
Try bed temperature lower, first layer slower so filament can cool down.
Pre heat printer.
Keep wind, or cold air away from printer.
Build a box around the printer to keep wind away from printer, you could try with open top, or a closed top, in the summer it could be to hot with a closed top.
Try different filament.
RE: Warping
Thank you everyone for the replies 🙂
Here is an example of some of the warping I am getting. I am running another print with some changes to see what happens.
To address some of your questions:
Prusament or Hatch box PLA 215 nozzle, 60 bed temp. Have also tried 50.
PEI sheet
Ambient room temp is 66F
My main warping occurs on the edges so I'm assuming it's.more about temperature instability as opposed to bed adhesion right?
RE: Warping
Hmmm. Try a very thorough cleaning of the print bed. Soap and HOT water.
Cheerio,
RE: Warping
These are my recommendations,
I always print Hatchbox PLA at 205c nozzle and 60C bed, I print prusament PLA & Prusa PLA at 220C nozzle and 60C bed. generally on smooth PEI sheet, nice and clean.
My main warping occurs on the edges so I'm assuming it's.more about temperature instability as opposed to bed adhesion right?
It will be both, and your first layer will be very important in that equation as well,
Good luck

RE: Warping
Although I would follow all of the other excellent suggestions here first, I would also suggest you turn on 7x7 bed leveling as well. It is hard to tell from that picture, but it looks like a rather large part that is probably using quite a bit of the bed. I would put this well below 1) Clean bed 2) Z height but maybe slightly above 3) Ambient temperature for PLA. Good luck!

RE: Warping
Apologies in advance to those who don't like me recommending this stuff.
For PLA which does not stick or warp, I suggest an adhesion enhancer. It's not a substitute for keeping the plate spotlessly clean, but in cases where PLA just will not appear to stick properly, this really helps. If I have a large flat PLA print I'll dab a bit of this where the corners and/or edges will hit the plate. It can save a lot of time, filament and frustration.
The product I use is the Layerneer Bed Weld. Glue stick works as well, but the Layerneer goes on with a much thinner coat and it does not show on the lower surface of the print. MagiGoo is another.
RE: Warping
For large prints, adding mouse ears to corners can help. It gives a bit more surface to grip than a simple brim, and they clean off easily.
