Description of the bug

Custom gcode for tool change errors because wipe_tower_x and wipe_tower_y were removed from placeholders.

Project file & How to reproduce

under custom gcode add:
G0 X{wipe_tower_x} Y{wipe_tower_y} F{travel_speed*60}

Slicing will error because the place holders no longer exist.

If the place holders will not be returning, how can one move the tool head to the wipe tower before calling the tool change gcode?
