How to Add Automatic Color Changes & Beeps to a 3D Print with Simplify3D for a Creality CR10 V3

It is possible to print multiple colors with a basic FDM 3D printer by using color changes added as G codes in the slicer. This is how I added six color changes to add detail and interesting design to the Titan submersible model I recently made.
I added color change commands into the G-code to print the sub's in multiple colors. The legs are grey, the body white, the face is silver, copper for the bolts and then either a blue or clear for the glass. The Launch in printed three colors with grey for the main body, silver for the on deck support structures and white for the four floatation devices. For S3D slicer I use the following code added on the Scripts tab under Post Processing.
{REPLACE "
M117 Layer XXX, Z=" "
M300 S2000 P100
G91
G1 X10 Y5 Z20
M600 S500 P100
G1 E-6.0 F1200
G90
M117 Layer XXX, Z="}; pause at layer, move head, play sound, change filament
M300 beeps to alert you of the color change. The G91 command makes the G1 move the extruder head using relative position moving the print head aside. M600 changes the color. Then I added a G1 retract to reduce any oozing. G90 goes back to regular position movements. Make sure you switch the TWO (2) XXXs for the correct layer where the new color begins.
~Just change the Layer XXX to the layer you want the new color start printing on in BOTH places~ i.e. Layer 526 AND Layer 526
First decide on the parameters for the print: layer height, use of adaptive layers etc. Any change in these setting may change the layer number at the point you want the color to change. In this case the color goes from the grey of the upper leg back to white at layer 526. By adding to the Scripts Tab under Post Processing in Simplify 3D slicer the following command the printer will automatically stop printing and eject the current filament and feed in the new one with a push of the controller button.
{REPLACE "
M117 Layer 526, Z=" "
M300 S2000 P100
G91
G1 X10 Y5 Z20
M600 S500 P100
G1 E-6.0 F1200
G90
M117 Layer 526, Z="};

PRusa, Orca, Superslicer, you can click on each layer change alongg the timeline and it will insert pauses, so you can change the fil.

That sounds quite handy! Much easier than adding them by hand for sure! Mullticolor is very cool. I've been doing Z Hop multicolor prints as well. Squeezing all I can from a single nozzle simple printer.
