I'm using an Anycubic Kobra 2 printer, it has a nice rubber pad at the back of the plate, which i assume is for wiping the nozze? However the printer profile Anycubic provides for prusa slicer doesn't use it at all, and actually has a fair amount of oozing because it heats the extruder first (which it then doesn't wipe away). So i decided i would add it myself. I'm completely new 3D printing, having only had the printer for a little over a week, so my solution may be a bit rough around the edges.

################ Start G-code with nozzle wipe and purge in back-left corner ################

G1 E-3 F3000                               ; quickly retract filament 3mm
G1 X90 F4000                               ; quickly move away from purge

The printer also end with the bed pulled all the way to the back, which I disliked since i would prefer it presented at the front for easy removal.

################ End G-code which presents the print for easy removal by pushing the bed fully forward ################
