    I’ve generated a rather complex tool path in which 3 tool changes are necessary. I didn’t see any T codes listed as available/ready to use here:
    https://github.com/synthetos/TinyG/wiki/Gcode-Support
    which leads me to my question; is there an accepted method for a manual tool change in the middle of a large G-Code program? For instance, if a T## is called will tinyG automatically home (G53) and wait until a continue command is given (~)? Or is my only recourse to break up the Gcode program into individual segments around the tool change to manually bring the spindle home and start the next program after the tool change?

    tinyG does not directly support Tool Change.

    The Chillipeppr GUI implements tool change capability, you could look at the sequence implemented there and manually implement

    Can the Gcode be altered to:

    …
    G53 Z0
    ! (Tool change)
    …

    Or will the ‘!’ be read and continue without the ‘~’ input from the user?
