G-code question

I keep having simple problems with prints and I know its G-code related or at least G-code fixable. The nozzle keeps hitting the print after it finishes. I would like to raise nozzle say 10mm after its done, Im sure I could figure out the code but maybe someone else has done this already and knows what worked best.

 

I had that problem. Try updating your firmware to the marlin one posted in documentation. That fixed the problem for me.

 

Where would i find that? Do i need newest version?
