Warping in first layer of printing
I'm new to 3D ptinting, I build the I3 MK3S kit and tested some models like Buddy the Triceratops skull and some Prusa logo's. all with no problems
Now I'm printing some coasters the first few had no issues, but now I see a slight warp in te first layer only when I print the same coaster.
I clean the sheet after every print.
Can anyone help me figure out what to do or what to check? Should I use the textured Steel sheet?
I'm printing with the silver PLA that came with the printer.
