I am using a Flashforge Dreamer with FlashPrint.
As you can see in the image below, there is a vertical ridge on one side of the print, along the locations where the printing of each layer starts and/or ends. Is there a way of fixing this by tweaking the internal parameters?
Many thanks in advance.

Best regards,
Jhinhwan
