Change tool path direction (printing direction) via Gcode?

I’m pretty sure that is the case. It seems the print head shifts slightly immediately after printing the overhang area. The one on the left the of image, print head prints the smooth area before printing the overhang.

Print speed is also a factor. Print head moves slower at the beginning of a new path and gradually reaches the wall speed limit as it travels until the end of the path. I was able to improved but not removed the artifacts completely by moving the seam further away from the trouble area, give print head time to build up the speed before it reaches the troubled area.

I’ve tried reverse engineer the Gcode file from Orca’s reverse on even feature without success.

Reversing direction should be a fairly simple task. I’ll put in the feature request.
