Weird curling problem when printing a thin item in 100% infil
The print job is a 4.5mm thick plate (lid actually) that is 155x160mm (See attached stl). It will curl on the front right side of the print when printing infills of 50% or greater. Al though due to time constraints I only tested in 20% (my normal go to infill), 50% and 100% (What my goal infill for this job was)
- The printer is a maker select 2 that I've had for many years.
- The bed surface material was replaced a few months ago also but not because of this, just because it was years old.
- I am using the same filament I've been using for 2 rolls from amazon (SUNLU).
- I've had no other issues w/ this filament and reviews have been good
- I print at 210/40C and always have w/o any issues
printer config:
- I have a duct w/ a cage fan that cools prints. Print cooling fan is running after layer 2
- all other layers 50mm/sec
print info and tests I've run on same job
- If I print the job at 50% infill it's better
- If I print the job at 20% infill it does not curl
- Tried to reduce printhead temp to 200, no change
- Bed is level to .001" as confirmed w/ a feeler gauge
- Bed is clear of any debris
I don't think it's pertinent here but I have included a copy of the item I was printing.My
