Thank you Ryan,
it would be very nice to have this feature.
My new printer has a lever to switch nozzle height during tool change procedure.
With this functionality I can write a script to switch the nozzle.
Example:
Before Toolchange G-Code
G1 X150 Y20 F15000
G0 Y0
{IF NEWTOOL=0} G1 X0 F5000 ; switch to nozzle 1
{IF NEWTOOL=1} G1 X300 F5000 ; switch to nozzle 1
..Thank you
