End of print crawl

I've been experimenting a lot with SF41 recently and today I noticed that when the print is over instead of x and y going home the nozzle creeps away in a very slow shuddering motion. It must be the gcode, I've removed it from SF41's preface and it just stops (like you would expect.) But it seems any gcode I use causes the creep.

Here is the current end.gcode.

G91
G1 F70
G1 Z7 F70; lifts nozzle 7mm from finished print surface
G1 F2300
G1 X-200 F2300
G90
M104 S0; turns off extruder

And here is what the feed back says after the last line of useful code.

Received: Serial Error: LineNr is not the last line Nr+1
Received: Resend: 3844 with parameter 3844
SendData: N3844 M103 *26
SendData: N3845 G91 *43
Received: Huh? M103
Received: Resend: 3845 with parameter 3845

There a bit more. But I can concentrate on typing it all out right now.

Any help with this?

It doesn't look like those errors are due to your end code. You don't have M103 in your end code but you're getting an error that it doesn't recognize it. I think those errors are before the end code.

If you want to go back to home, why not just send a G28 X0 or G28 X0 Y0 command?
