I just started installing my Chameleon 3d Mk2. I have an Ender 3 pro I looked and found this video: In it the Extruder control wire from the Ender 3 is used to control the Extruder on the Mk2 instead of the switch being pressed for 3 seconds or 5 seconds. Still uses the switch to choose filament 0-3 Is there and Gcode for tool change that doesn't use the 3 second delay? I need one that just uses extruder commands instead of the long switch presses to load and unload. I tried the gcode generator (Beta) but it always assumes the extruder is separate from the Chameleon box Andy
