It seems like the issue with the violet-colored filament not adhering well to the bed could be specific to that filament. Here are a few suggestions to troubleshoot the problem:
Check Bed Leveling: Ensure that your bed is leveled correctly. Sometimes, poor adhesion can be due to an uneven bed.
Adjust Printing Temperature: PLA filaments can vary, and each color might have slightly different optimal printing temperatures. Try adjusting the printing temperature for the violet filament to see if that helps with adhesion.
Clean the Print Surface: Make sure your print bed is clean. Residue from previous prints can affect adhesion. Consider using a bit of glue stick or a specialized printing surface like BuildTak for better adhesion.
Enclosure or Draft Shield: PLA can be sensitive to drafts or temperature fluctuations. Consider printing in an enclosure or using a draft shield to maintain a consistent temperature around the print.
