I have a Monoprice Mini V2 that is printing acceptably - until today. I was printing a cover that was supposed to have a uniform radius. However, on the left it printed correctly, while on the right is wrong. STL from SolidWorks, Sliced in Cura, and converted to gcode by Cura. I used the SD car (which has never given me trouble). Material is PLA at 195C, bed temperature of 50C.
What is the likely cause of this?
