Two prints from the last two days! From my new favorite thing. Can’t wait until my second one gets here.

Sure thing Bill, here it is. I'll post it here for anyone else to use (this is 3dc as extruder code with 3dclippy and crtouch for anyone reading). Still fine tuning the filament loading mm by mm so I'm not too concerned about that, but also some of the stringing appears to be caused by prusa and the wipe tower, if I can get rid of with gcode edits that's even better though. excuse my comments and edits, but I'd love your input on any changes I've made as well since you designed the thing:

; 3D CLIPPY TOOL CHANGE CODE ; Auto generated 3D Chameleon Tool Change GCode for PrusaSlicer - Chameleon As Extruder ; retract now to the cutting point to avoid ooze G0 E-55 F10000 ; go to holding position to unload the stock extruder G0 X220 Y210.8 F4000 G91 ; set motions to relative for the button presses ; - 3D Chameleon Tool T{next_extruder} - ; unload extruder {previous_extruder} ; begin switch from extruder {previous_extruder} to extruder #{next_extruder} ; M117 Unloading Tool T[previous_extruder] M92 X8; set x steps per mm to a small value (very high torque) G92 X0 ; set to 0 so we have a lot of room to travel M117 Cutting ; cut off the filament tip G0 X315 F10000 ; quickly cut the filament strings off G0 X-315 F10000 ; ok... go back to normal position M117 Restoring M92 X80; restore x steps per mm to normal value G92 X220 ; restore original position M117 pulling and homing G0 E-2 F4000 ; pull filament off blade (this will pull off the tip if it didn't cut all the way through) G0 Y-10 F4000; move away from clips ;G28 X R0; home the x axis to reset the position; *** HOMING DISABLES MESH LEVELING!!! *** replacing with next 3 lines G90 ; switch to absolute mode G0 X0 F4000 ; move X gantry all the way to the left G91 ; switch back to relative mode G0 Y10 F4000 ; push off tip into ptfe tube G0 E5 F10000 G0 E-7 F10000 M117 retracting ; retract it back out of the extruder G0 E-100 F6000 G0 E-58 F6000 ; ok - out of extruder - press button to remove it all the way ; load extruder #{next_extruder} M117 Loading Tool T{next_extruder} ; always reset to extruder 0; why? Lets just use an if statement again {if next_extruder==0} G0 Y3 F4000 G4 P500 G0 Y-3 G4 S2 {endif} ; press the button for each extruder (1,2,3) {if next_extruder==1} G0 Y3 F4000 G4 P900 G0 Y-3 G4 S2 {endif} {if next_extruder==2} G0 Y3 F4000 G4 P1400 G0 Y-3 G4 S2 {endif} {if next_extruder==3} G0 Y3 F4000 G4 P1900 G0 Y-3 G4 S2 {endif} ; - 3DC Process Tool {next_extruder} - G90 M83 ; return to position top middle G0 X105 Y210.5 F6000 G0 E100 F6000 G0 E100 F6000 G0 E23 F6000 ; one at a time G92 E0 M117 3D Chameleon Tool T{next_extruder}

Here's what all my retraction settings look like in prusa too. I have about 3-4 inches more ptfe tubing than you did in your ender 3 v2 YT videos
