Nozzle drags across model at end of print

Hi, this is probably an easy fix in Slic3r, I just can't find it.

At the end of any print (the gcode of which I generate in slic3r), the nozzle seems to actually lower a bit and drags across whatever the final part was, leaving a nasty scar. Any ideas why this is happening?

All a Z lift in the end GCode section before the move away from the model

G1 Z<Z+1> F300 ; lift Z
G1 X0 Y200 F1200 ; move away

You need to replace the Z part with the command relevant to your slicer.

That sure sounds unusual. It definitely shouldn't lower. I assume you checked your end g-code in Slic3r and possibly OctoPi?

Re: Nozzle drags across model at end of print

I use this ending gcode move-away commands:

G91 ;set relative mode
G1 X-255 Y200 Z30 F1200 ;move 30mm up and to the back corner
G90 ;back to absolute mode

It works regardless of current position of extruder.
