Hello, Im struggling with this issue also. what would be nice is, a preSwitchExtruder1to2.gcode and preSwitchExtruder2to1.gcode and corresponding post switch files. I have a handful of things I would do differently when switching from 1 to 2 versus when switching from 2 to 1. anyone had any experience with this or know of a plugin that would allow you to easily perform different code when switching between either extruder? thanks

Hey Im trying to do this exact same thing. Im using a ramps 1.4 board right now with marlin. Ramps has D8 D9 and D10 outputs. D8 is extruder 1 D10 is heatbed and D9 should be extruder 2 but will switch a relay going to a heat gun inside the box housing my printer. Is there any way to add additional temp controllers in Marlin? Seems like there must be since Rambo boards have 4 thermister inputs built in. How can these thermister inputs be used?? thanks for any advice!
