Good day!
Q: I have Ender 3 at the beginning of printing draws a line on the left side of the platform, it is in the slicer settings (not found. I Use Cura 3.5.1)?
Because in the generated G-code it is present:
a piece of code from the head of the file:

G1 Z5.0 F3000 ; Move Z Axis up little to prevent scratching of Heat Bed
G1 X0.1 Y20 Z0.3 F5000.0 ; Move to start position
G1 X0.1 Y200.0 Z0.3 F1500.0 E15 ; Draw the first line
G1 X0.4 Y200.0 Z0.3 F5000.0 ; Move to side a little
G1 X0.4 Y20 Z0.3 F1500.0 E30 ; Draw the second line
G92 E0 ; Reset Extruder
G1 Z5.0 F3000 ; Move Z Axis up little to prevent scratching of Heat Bed

I have the same problem with my Ender 3, but mine only started when I went from CURA 3.4.1 to CURA 6.0 sadly I am not smart enough to know how to fix it.

That looks like it is "wiping", below is the start Gcode I am using (though I changed it so it starts a few mm in rather than 0,0)

You have to remove this code here, it is prepended by Cura after slicing.

This peg-top was made with the Replicator 2 using the clear filament that shipped with the unit.
