Doing Filament Change Command (M600) using limit switches

[DarkAlchemist]

Here is a thread you might want to read:

After I posted I did a Google search for M600 gcode and up popped that thread from April I believe. I have to admit I got lost because I looked at the Marlin_Main.cpp and I see nothing locking me into the LCD panel but it sure seems like it would rock if it works.

As I said I use Pronterface to print with but a lot of people seem to use Repetier and it has some nice things for dealing with this. Move the head up and out of the way and remove the filament, load in the new filament, and purge the head then continue printing.

I am still wondering how people do multi interlocking pieces because the bed must cool down for the print to pop off and your G29 matrix is surely (I say surely because I have not tested this) off at that point. 50c vs 85-110c.

edit: Oh, I almost forgot but I use a Ramps 1.4 board and I am not even sure what that board was/is in your write up/post.
