the deformation is the fan

@sgk what material is it that you are printing?

Looking at your gcode file you have set the bed to 90C. That is waaaaay too hot for PLA and I doubt your extruder temp of 195C would be correct if it was PETG or ABS.

Leads me to think that @oliof was right and the deformation at the bottom of the part is because it is too hot and the part is melting!

TYPE:Custom
M104 S195; set extruder temp
M140 S90 ; set bed temp
M109 S195 ; wait for extruder temp
M190 S90 ; wait for bed temp

but if I have but not 90 it does not adhere to the bed.

@engikeneer
and as we see in the photo it is already peeling off on the corner

@engikeneer I've been fighting for months, I've changed a lot of things but still the same I'm at the end of the line

[oliof]

@sgk what is your print surface?

[A Former User]

@oliof 350x350mm

[oliof]

what material? painter's tape, PEI, Pertinax, Buildtak,....?

[A Former User]

@oliof pei

[oliof]

@sgk make sure there is no protective sleeve still on the PEI. Then clean it with Isopropyl Alcohol. Then give it a scuff with steel wool.

For PEI the right temperature for PLA is 55-65C. If that doesn't stick there is another issue you will need to fix. 90C is definitely wrong.

@oliof I put a new pei plate it may be the same because the aluminum plate is 10mm

[oliof]

depends on where your thermistor sits. But going 90C is still wrong. I would suggest to let the bed soak for 10-15min at 60C then try again.

@oliof ok

[oliof]

Don't forget to reslice with adjusted bed heat settings.

[A Former User]

@oliof yes but that has nothing to do with the quality of the piece if

[oliof]

Let's solve one problem at a time. I you don't have proper adhesion, the rest of the print will always look bad no matter what. So that needs fixing first.

@oliof yes ok thank you

@oliof
I put new pei my ca does not adhere to 60 degrees

[A Former User]

@oliof
as the aluminum plate is 10mm I have to heat for 30 minutes to 60 after it holds
