I'm using Cura 3.4.1 with my Printrbot Simple Metal Extended. The X-axis is not centering correctly. You can see in the pictures below that the print is in the center of the print bed in Cura, but actually prints substantially to the side. I have not changed the default settings for this printer in Cura. This greatly decreases the size of the prints that I can make using this printer and Cura.
I must be missing something because I can't imagine that Cura would remove this feature. I can no longer find the manual extrude and retract command in Cura 3.4.1. I'm using a Printrbot Simple Metal Extended. I've read that the these controls should be under the Printer Controls menu in the Monitor page, but they do not appear for me. I only see X, Y, and Z axis and Jog Distance controls. Without these controls I cannot use Cura to load and unload filament or clear jams.
