    Hopefully this is a simply one, but I was unable to find any command outside of using G1 Zxx. I am wanting to have a command sent after the print is finished to lift the Z axis by say 5mm over the current position.

    I had been using a command to park the extruder in a specific spot when finished, but then ended up printing something higher than that spot and my extruder made a hole right in the side of my print - goodbye 6 hours.

    G1 Z+xx I saw mentioned, but it does the same thing as a normal G1 Z.

    Maybe this has to do with issuing a relative or absolute command first? Any help?

    Relative ... so you switch modes first:

    G91 ; relative movements
    G1 F150 ; slow Z rate
    G1 Z5 ; Z up 5mm
    G90 ; back to absolute

    Thanks a bunch. I figured it had to be something simple I was missing. I had just been lifting the Z to 200 after the print, but then found that when I went to do the next G28 that there were horrible grinding noises.

    at a guess your lifting to far so its "straining" to come back down :D. 5mm would be more than adequate.
